A web gallery


Having reached this far along the course, I know what I would like from a web gallery. I had a web gallery under an email address which stopped when the service provider changed. This worked OK for my needs at the time and now it is time to look seriously at creating and maintaining one. 

I found a stand at The Photography Show (2014) advertising Web Sites which I had a look at. However, I felt they they were very professional, expensive  and for photographers running a business. At the moment, I need an arena to display my best images which I can add to. I have subsequently looked at various online companies and I think that Clikpic has the best layouts and templates for my needs at this point. I could start with a basic layout and cost price and and add to it as my collection and needs grow. Once I am established I would then look at a custom built site that I could edit as my portfolio and business grows.

I learned from a seminar I attended at The Photography Show (2014) given by Catherine Connor of Aspire Training that the site should be eye catching and say more than just my name. If I want the website to help attract people to it, I have to have the type of photographs that people are interested in on it as well as it being unique to me. I think it will take more planning and forethought than I originally envisaged and in the meantime, I shall record what I like about other photographers sites.

Sharpening for print

I started off by taking a portrait image which had been processed but not sharpened.

Using Photoshop and unsharp mask, I created 3 versions one close to the onscreen version, one fairly aggressive, and more aggressive. On screen, I thought I could tell a difference in the amount of noise visible in the background but this didn't transfer itself to the print. Using a magnifying glass and torch, there were a few areas such as the zip and pupils where I could tell that that sharpness had been applied.  I was not convinced that this had done the job I intended.


base
amount 90%
amount 150%
oversharp















I checked my camera, wondering perhaps if the settings in my camera were oversharp and maybe this was why my image had not sharpened visibly.

I took another image with more contrast and cropped to A4 using about a quarter of the photo. This time the exercise worked. 


base
amount 90%
amount 350% 
amount 250%
Summary of lily sharpening


Using a radius of 0.5 and a threshold of 1, I altered the amount of sharpening from the unsharpened image to 90%. There appeared very little difference on the monitor when viewed at 100%. In print and using a bright light and a magnifying glass, the difference is highlighted in red above. A few odd pixels had been brightened and in the middle there was a brighter edge along two of the stamens.

The effect of this surprised me. I hadn't really understood how unsharp mask worked and had been cautious in sharpening. The suggested starting threshold value is 90-120%. Gulbins and Steinmueller (2011) 

I kept the radius and threshold the same and altered the value to 250% to see the effect, illustrated by the blue line above. I could tell on the monitor that this was oversharp. A dark line was starting to become visible along the bottom stamen and the white petals had a darker patch on them (I wouldn't have called it a halo). 

I had still not seen the effects of noise, so kept the radius and threshold the same and increased the value to 350. On screen there was noise on the petals. This transferred to the print. The difference between 250 and 350 was alot more oversharpening and an increase in noise.

radius = "number of neighbouring pixels that are altered by the sharpening process" threshold = amount "of pixels to consider as an edge" 
amount = "how strongly edge contrast is increased" 
Gulbins and Steinmueller (2011) 

The exercise confirmed to me that at a threshold of 90%, radius 0.5 pixels and I would still have to be careful with areas which were too sharp, so continue to be cautious. There is an argument for only sharpening where it is needed. I felt it was a very beneficial exercise.

Assignment 4 Real or fake?

Introduction
This assignment explores the issue of technique and ethical choices which are made in photography by designing and producing a photographic image illustrating an imaginary magazine. During the exercises and assignment work, I had the opportunity to clarify my thoughts and question my beliefs on whether alteration should take place and if so, what is acceptable and how tolerant are the viewers?

Context
During November, the Dukeries Rally passed though my local forest (Sherwood Pines) and I watched a couple of stages. Whilst there, I experimented with a few photographs. When considering a subject to study for this assignment, I recalled the event and dusted off my son’s radio controlled rally car. I planned to juxtapose it against the forest as a background to make it look like it was in the World Rally Car (WRC) series. We had other models of remote control cars which I could use to insert into the cover of my imaginary RC Car Monthly – a magazine for radio control car enthusiasts for a piece on restoration. I considered my plan a challenge to my manipulative Photoshop skills so decided to make the magazine cover something which would develop and enhance my skills.

Other themes I pondered were monster trucks, mountain biking, and food.  An internet search showed there were about four international radio control car magazines already on the market. By looking at magazines online and on sale in the newsagents, I had several ideas in my head.

Research on existing magazines
The entire collection of car, radio control, bike and food magazines I looked at had a front cover in portrait orientation. There were various designs for car and radio control covers; some used a bird’s eye view, some juxtaposition where a whole car or part of a car was set against a realistic background and a few had a plain background (shiny or dull). Magazines either had a large single picture, more than one car on the cover, or one car and an insert picture. Car(s) were positioned on the whole on the diagonal and one magazine had a couple of covers where the car was more of a triangle shape. Backgrounds either took up the whole of the page or were designed so that the writing was placed in the sky. Different types of cars had different characteristics of placement – for example most Porsche and race cars had four wheels on the ground, dirt buggies and monster trucks were on rocks and when one or more wheel was off the rock, a shadow was present. Most of the cars looked stationary with very little wheel motion and no spraying dirt.

Background Image
First of all I needed a background in which I could juxtapose my car. Considerations were orientation, scale, balance and colour. My original rally images were taken in landscape and I saw from this that I needed to take a background with portrait orientation.

I planned on paper how I thought the final image would look and decided to divide the frame into thirds. My idea was that the car, when positioned, would sit off centre on a diagonal and I would be able to alter the size of the car to fit.

I walked through Sherwood Forest looking for tracks and surroundings where an imaginary WRC rally may have taken place. Colours had to complement a red and white rally car, and trees in the background would add contrast to the final image. I wanted to leave space for positioning the title, subtitles and an insert picture.
I thought this was an acceptable background to place a rally car. No major changes were made at this stage – only checking colour temperature and a slight tweak in curves. I opened the image as a background in Photoshop CS3 and built up layers and vector masks on top of it.

The rally car image
Version 1
I thought (at the start of this assignment) that the car would have to be positioned in roughly the same angle that I wanted it to be in when cut out and pasted onto the background. In this image, the car was propped up on yoghurt pots. I cut and pasted this onto the background and realised that I could use the transform tool. I took the car outside to look at what the effect of natural lighting would be on the car.        

Version 2
The lighting outside reflected the trees onto the bodywork. Although my image contained trees, I felt that the reflection was unrealistic. I liked the yellow colour of the lights rather than silver to give a shining effect. After cutting and pasting this image into my background, I decided to change the direction of the car.



Version 3
With the car direction changed I decided to take the car indoors again as the paintwork showed too much reflection.





Version 4
Car now facing the correct direction, lit from a window rather than tungsten lighting. No reflection visible on bodywork. Black velvet used as a base because there was enough definition between wheels and material to enable polygonal lasso to work effectively.







Amalgamated image
Space left at the top for a title, space below right for insert, complementary colours (red / green), car positioned on track.



















Exploration of areas of adjustment and manipulation to make a successful image
I cut around the car using the polygonal lasso tool and cut and pasted it into Photoshop CS3 as a new layer. Using the eraser, I removed the excess background. I cut and pasted the antennae across separately and attached to the car so that I could work at a different magnification. I cut and pasted the headlights across and fitted them using the transform tool to scale them in place. Using the transform tool again, I moved the car around, changed the scale and the perspective a little to make it look more natural on the page. I added a drop shadow gradient to this layer.

Tools used so far: cut and paste to combine two visual elements in one photograph, erase, transform scale, rotation and perspective, addition of drop shadow gradient.

Justification for using these tools was that they were necessary to make the car blend into the background and still look real. To have taken an image of an RC car in the forest would possibly involve a forced perspective to which one could still question the reality. By cutting and pasting an image and erasing the background to tidy it ensured the image fitted in to the background as I wanted it to.

I questioned the use of the eraser when my image would not quite fit in the white frame I created for the magazine title. I shaved off a little of the bumper and thought that it was acceptable because it was not a distinguishing feature. I could simply have resized the car without altering it.

Transform, rotate and change perspective were tools that I discovered which made manipulation so much easier. This cut down the work which I thought I was going to have to do by hand with re-positioning the car. So from this point of view, I thought it was acceptable because time taken to create an image must also be considered.

I applied a drop shadow layer style to the car which  I considered as acceptable because in reality the car had a shadow. Because I had used black velvet as a base, the shadow did not show up. The background was taken on an overcast day, but even then shadows are still visible.

Considered area of adjustment
I applied a gradient to the whole background image before starting to add titles to see if by toning down the brightness the image was more acceptable. I tried several types of gradients before removing it.

I debated whether to add a rectangle with a gradient behind where I was placing a title or subtitle. I did not think this looked effective either for my image, although some magazines appeared to use a technique similar to this.

At this point I was still considering the position of the title and whether to retake the background shot with more sky so that the title was not distracting. I recalled Kit Car magazine which I used to read had quite an expanse of white / pale page at the top. This was similar to a copy of a Canon EOS magazine I had.










Insert photograph
I used tungsten lighting to light the battered box and old model to illustrate a seasonal project for the winter. I adjusted the white balance in Photoshop and did a small amount of cloning and patching on the mini. I left some burnout and reflection visible as it was a “home project”. I cut around the shape and erased the rough edges after importing onto a rectangle shape layer on my Photoshop image. For the purposes of this document, I imported the cut out shape into a new blank page and changed the colour to one similar to that used on my original image.

Tools used: Cut and paste to combine two visual elements in one photograph, erase, transform scale, rotation and perspective, addition of drop shadow gradient, clone and patch. I felt there was too much burnout from the overexposed area on the roof and bonnet of the purple mini so replaced some of the pixels using clone and patch to enhance the image.  I changed the background to give more of a studio effect which I thought was acceptable as space was at a premium. I had taken an image with tools laid out too, but thought the image was too cluttered.

I opened the image in Photoshop Elements 5 and made some finishing touches such as a band across the bottom and changed the font styles. 

Finished cover

Ethical Justification
I like to produce realistic, acceptable photographs that inspire others and can be used for teaching or storytelling. I think surreal images are acceptable but they have to be believable. For instance, one of the collections that inspired me at Focus on Imaging Derby 2013 were  photographic images of plants by Putput which when viewed from a distance looked realistic but actually contained household objects such as spaghetti servers and body polishers. I was reminded of this work when researching photographs of Sian Bonnell. I felt that in keeping with the type of magazine I had chosen to illustrate I needed to keep my image real to attract the readership, although my final cover had combined images. I reconsidered my cover and whether I should have chosen a different type of genre, and the more I thought, the more ideas I came up with. I think that for where I was at the time with learning how powerful Photoshop is and what it can do, it was good to start with something quite realistic because I knew what I wanted to achieve and reached a point where I was satisfied. I think if I had created a surreal image, because it is not my type of image, I would still be left wondering if it was successful.

The ethical impact of the magazine on the environment is about encouraging recyclingI decided to include a photograph which could carry a restoration story in light of the fact that Christmas had just happened, children receive shiny new toys and old ones are sometimes put to the back of the cupboard. Perhaps their old, broken toys which need recycling or mending could become projects in the long winter evenings, so it seemed appropriate to include this on the cover. I used a natural environment to encourage people to go outside with their RC cars which could be seen as encouraging a healthy lifestyle.

The other consideration for my magazine cover was whether it would sell or just sit on the shelf.  I tried to pitch it in the middle of magazines; not elite and not a weekly edition. I imagined it being made of reasonable quality paper and being kept by the reader for some time as a reference magazine.

Conclusion
This assignment investigated the issue of adjusting and manipulating an image and still making ethical choices when producing a photographic image illustrating an imaginary magazine cover. During the exercises and assignment work, I was able to clarify my thoughts and question my beliefs on whether alteration should take place and how much was acceptable. I think my imaginary readers would find this magazine cover acceptable as it is not too far removed from the truth.

Key learning points from assignment
·   My initial point for using Photoshop for manipulation rather than enhancement at the beginning of the exercises and assignment work was virtually nonexistent. I took a logical approach to researching how to make things work and gradually built up skills which after some practice became second nature. I found some processes relied on trial and error to decide which methods worked for me. I was able to look at an image taken previously and decide which methods of manipulation would work.

  •  I began to understand how layers and vector masks worked which is an area I knew needed development.
  •  I felt a sense of achievement of being able to do more creative work in Photoshop.
  • I was able to explore how I felt about altering images and question the reality of images in magazines and adverts I looked at.

Areas for further development
  •  Use the available tools in Photoshop to become more creative. Now that I have completed this, it feels quite “safe”. However, at the beginning of the assignment, I found the task very challenging.
  •  Improve (faster, more efficient) work flow with Photoshop.

Response to Tutor Feedback Assignment 3

Assignment 3 DPP Retaken photos and response to tutor feedback
When I submitted my assignment, I was not 100% happy with some images and had included my thoughts on why I thought they had not worked in my original assignment. It was encouraging to read that my tutor agreed with me and advised how I could improve my images. I was able to revisit the property and look at it in a new light. My tutor thought I was beginning to understand what made a black and white image, and I must admit that when I first started the Monochrome project, I had little idea of the work required to turn the image from a black and white conversion in Photoshop into a black and white photograph. The other point of note from my tutor was to pay more attention to the framing of the subject. 

Exterior
Retake F8 1/90 ISO400 20x1.6=32mm focal length using a telephoto lens
I originally visited the property on a sunny day. However, it was not so good for the panorama which I wanted to include as an establishing shot. I decided to retake the image in more even light so I revisited the property on a dull day. My tutor commented that in my original, I had corrected the verticals in my image but not the horizon, and the image was unbalanced.  

original
1/45 F16 ISO200 18x1.6 =28.8mm 
By changing my position and looking at the house straight on, I think I have balanced the image. As the tripod was placed on uneven ground, I took great care to ensure the camera was as level as possible by using live view before I took each image. When processing, I applied a grid so I could check that the ground was level and rulers to check that the house was placed with the same amount of space on each side. I think what remains is an optical illusion.

I cloned out the lights which were shining in the church; photo merged the images together in Photoshop and altered the vertical and horizontal perspectives. Using a new adjustment layer, I set the black and white points and increased the highlights and mid tones to increase the contrast on the building. I think the result is more balanced with better lighting and a better position although in my opinion it gives a more oppressive feel to the building. This shows form and tonal contrast.

Columns

1/90 f4.5 ISO400 New focal length = 70x1.6=112mm 
My tutor agreed that the texture of these columns was shown in the black and white image. Her advice was to include only part of the columns and use a longer lens to compress the subject.  Using my 70-200mm lens (x1.6=112-320mm), I experimented with only part of the columns. I originally took this at an angle but straightened it because I did not want the columns to look like they were falling down.      
   
original
1/350 F13 ISO200 32x1.6=51.2mm
When processing the image, I cloned and patched an area where the window was missing. (I did not have these skills when I did the original assignment. I developed them subsequently as part of the exercises in part 4.) I corrected the lens distortion and opened an adjustment layer to increase the contrast. The texture and pattern is still visible. I was pleased with the resulting effect.
I think this works because it shows all three qualities of texture, form and tonal contrast. It actually showed more texture and form than I expected it to.

Low Key
1/45 F5.6 ISI400  40x1.6=64mm
Original assignment has now been altered to say low key instead of high key. 

I agree with the comments on the framing. I looked at the original image – I think it needs deleting as there is not enough space around it. Unfortunately the weather / lighting conditions during my revisit were not conducive to repeating this image.

Original
1/10 F16 ISO100 10x1.6=16mm 
 I looked at the graffiti which had been etched into the darker areas of the concrete. I set the black and white point in levels and altered the slider bar to increase the dark tones. By increasing the yellow and blue tones within the image I was able to bring out the white writing and the area of wall which had been lit naturally. This made the graffiti stand out. When the image is magnified, the weathering marks from the rain running down the concrete are noticeable. I think this is acceptable, although not my favourite image. As the lighting conditions were completely natural and the day was overcast, I had to rely on small changes in the light for this image. It shows texture and tone.

Rear of House
1/90 f8 ISO400 18x1.6=28.8mm

My tutor had commented that the original image is taken at a rather odd angle.  “You have some fall off caused by the very wide lens.  A more straight on approach (if possible) would allow for the fall off happening evenly on either side of the building.  The image may be better suited to a less wide lens. There shadows on the left hand side are dark (although detail can be seen and this further adds to the unbalanced feel of the image).”
The original angle of view was odd because the drive extended around the back of the house and past the church and the church’s flying buttress also protruding into the frame. As I had retaken the panorama to give a more straight on view, and was deleting the high key image, I decided to work on balancing the view with a using a wider angle lens and looking specifically at the balance within the frame. I cloned out the yew tree branches in order to balance the image and allow the eyes to wander into the image along the drive.
                                            
Original
1/10 F16 ISO100 10x1.6=16mm
To process the image, I increased the red and yellow sliders and decreased the blue and green which brightened the house and brought out the detail and colours in the stonework.
I like this image which shows tone and volume.



High Key
1/60 f4.5 ISO400 70x1.6=112mm
This is one of the areas where I felt I had not succeeded, confirmed by my tutor. I revisited black and white images in the text books. Freeman (2009) states that “there usually needs to be some smaller, darker elements that are integral to the image.” This image has some dark elements that the eye is drawn towards up the column, and the darker grey lines also direct towards the top of the column.

 original
1/30 F16 ISO200 10x1.6=16mm
As the histogram was mainly to the right, I set the black and white points and used levels to alter the slider bar to the left to keep the mid tones values fairly high.

I think this image works because it shows form. If anything, the crop is too tight around the top because I rotated the image by 3 degrees to square it up.





The remaining images submitted in my assignment were acceptable.
Relief work through opening
“In this image the tonal values are controlled so that the difference can be seen through the gap in the wall. The angle of view is quite tight so a little more space around the hole may help.” I took different lenses and camera body (full frame) on my revisit to look at this image. It didn't seem to make any difference what kit I used and it was only my position which made a difference to the plaster through the window. The door was locked as the site is open all the time and the larger windows did not give the same view.  
Plaster
“In this image – black and white really does come into its own. The use of tones enables the textures to be captured really well. A good image well done.” This was one of my favorite images.
Down the corridor
“Here you have kept the detail in the interior by sacrificing the window at the end of the corridor. For me the puddle draws the eye down the corridor and provides a useful pause in the frame.” I was pleased with this image and the evaluation given as I had considered removing the puddle.
Through the Window
“This image works by keeping it very straight on and symmetrical in the framing. The image would probably have more power in colour, as a blue sky would really stand out through the pattern in the window. However the landscape does have good tonal range.”

Tutor Feedback
Overall Comments
It is clear that you are researching what makes a black and white image and applying this to your evaluations.  At times your framing feels unbalanced and you may wish to pay attention to this.

Feedback on assignment
Demonstration of technical and Visual Skills, Quality of Outcome, Demonstration of Creativity
The exterior
Here you have completed a panorama – which presents many technical challenges.  The brightness to one side causes some issues – and when you are stitching images together you would try to avoid such lighting conditions.  The verticals are corrected but the horizon could be straightened a little, as the image feels unbalanced.

Columns
For this image the texture of the columns is bought out in the black and white.  I would consider going more abstract and only shooting a partial section of the columns.  If you experiment with using a longer lens you can see how this compresses the distance which such a subject matter.

Single column
This image is more abstract and deserves to be viewed on a larger scale as the eye is taken up the column.

Door scroll
Do amend your evaluation text to say low key rather than high key! An interesting image but I would watch the framing as the top edge is very tight on the scroll – a little more space around it would be more pleasing to the eye (otherwise if you want to crop through something make it definite rather than just clipping the edge).

Rear of House
This image is taken at a rather odd angle.  You have some fall off caused by the very wide lens.  A more straight on approach (if possible) would allow for the fall off happening evenly on either side of the building.  The image may be better suited to a less wide lens. There shadows on the left hand side are dark (although detail can be seen and this further adds to the unbalanced feel of the image).

High Key
I agree with your comments on this image.  If at all possible I would try for another trip to the location and reshoot some of the images.

Relief work through opening
In this image the tonal values are controlled so that the difference can be seen through the gap in the wall.  The angle of view is quite tight so a little more space around the hole may help.

Plaster
In this image – black and white really does come into its own.   The use of tones enables the textures to be captured really well.  A good image well done.

Down the corridor
Here you have kept the detail in the interior by sacrificing the window at the end of the corridor.   For me the puddle draws the eye down the corridor and provides a useful pause in the frame.

Through the Window
This image works by keeping it very straight on and symmetrical in the framing.   The image would probably have more power in colour, as a blue sky would really stand out through the pattern in the window.  However the landscape does have good tonal range.


Learning Logs or Blogs/Critical essays
Context
Your blog is showing good development.  The reading list is really evolving and do keep adding to the list of sources. 

With regard to the labels on the right hand side – can you add a tab for research and then tag any post where you refer to your research. 

I see that several of your posts do have reference to research within them and it would be good to be able to scroll through and see all the research you have done easily.

For the assignment it would be better to have your evaluation with each image as scrolling up and down all the time can get confusing and disorientating.

I always think that the work of British photographer Edwin Smith compares well with Eugene Atget.
