Jordan Wardle created photographs for an exhibition that included macro and abstract images. Their favorite photos were an eye with stars edited in and an image of Matt with his eye and mouth covered. Most feedback indicated these photos were well edited. The fence photo was seen as the least interesting since it was not edited. Suggestions were made to edit the fence photo in black and white or change its colors. The baseball and eye/mouth photos were said to have benefited most from editing. Overall Jordan was pleased with the exhibition but would focus more on abstract photos if they did the project again.

Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.
3. » This unit was photography and I really enjoyed this. We had to research different areas that make up
photography like macro abstract and others. I really took a liking to Macro photos as I like how it takes
unimportant objects and shows them in more detail and makes them fascinating. Taking an image closer to the
object makes the object more interesting. From all the research we did I chose to do Macro images in my
exhibition along with Abstract. I really liked Abstract photos as it gives a different view to normal objects. So I
also decided to use Abstract in my Exhibition.
4. » I got the inspiration for most of my images from Just walking around and finding areas that will look nice
however some I got from the internet. For example, the Image where Matt has his mouth and eyes covered up, I
got the inspiration from google images where I saw a character from Pans Labyrinth. Inspiration is really
important as it gives ideas for images to take with your own twist. I believe that inspiration is really important as
it helps decide ideas if you are stuck.
5. » The cameras I used were the Canon EOS 600D and 1100D. These cameras where good at taking abstract photos
however they struggled with macro as I did not use and extra lenses.
» I then used Photoshop to edit these photos on a PC and make them look nicer for the exhibition.
6. » I edited most of my photos in different way to make them look nicer than the raw image.
» One of my images were a baseball that I made black and white on certain parts to add emphasis on some of the
different sections.
» I used different tools to edit my photos like colour changes and mode changes however I learnt new ways of
doing things, for instance I learnt how to select things by colouring in the section I want then clicking the
keyboard shortcut “Q” to quick mask.
» The only photos I didn’t edit were the chain link fence as there was not much I could have done to make that
look better.
7. With the eye image I wanted to achieve an edit were the
coloured section of the eye was replaced with the stars in
the sky. To achieve this I had to:
1. Get the image you want to edit on screen! 2. Then go to
the brush tool and press Q, then colour in the eye (part you
want to edit). 3. Then after press Q again. (it should create a
selection).
4. Put the image you want to replace on top of the first layer.
5. Then delete the selected area on your new image!
6. The finally change the mode of the sky image to “overlay”

9. ˃ What are the strengths and weaknesses of your photographs?
I reckon my strengths lie in abstract images. I believe that some of the images I came up with are very creative
and I can capture this creativity relatively easily. However my macro mages might look nice now however it
took a long time to focus the images correctly and make them look nice originally.
˃ Are you pleased with them?
Yes, I am pleased with all my final photos except for the edited image of matt (eyes and mouth) which I
believe could have been edited a bit more realistic. However the other images I am quite happy with
especially “Stan’s eye” which looks really nice with the image in his pupil.
˃ Has it turned out the way you planned?
Overall the images have turned out the way I wanted however it took a lot of time trying to get the image
perfect. I planned for certain images to be taken (in my drawings, like a spiders web) however in the current
weather it was extremely difficult to find any.
˃ How you improved as a photographer?
I have improved in taking macro shot by far. At the beginning of this topic I didn’t know how to focus correctly
close up or how to navigate through the camera settings properly but now I am more confident in doing so.
˃ What would you change or do differently if you did this project
again?
The type of images I took. I would have focused more on abstract images as I have a larger
interest in this field compared to macro which after a while got quite repetitive.

12. Edited Original
- Macro/abstract
In this photo I made the blue area around the pupil like space by merging it together.
I really like this idea as it works really affectively . It really does look like there are stars
in the eye.
This is one of my favourite photos as I really like how it turned out.
13. Edited Original
- macro
This baseball has been edited a lot, I have changed the colour of the shadows and light
areas (mono chrome) and also I have cropped it to emphasise the ball and not the
fence.
I like this photo as it is different to others and will stand out.
14. Edited Original
- Abstract
This photo has been changed very slightly, I made the lighting in the top left a bit more
brighter as I liked how the sun would look on the branch.
15. Edited Original
- Abstract
This photo has been edited by changing the leaf to black and white and leaving
everything else as it was. This makes it look nice as it shows the background easier.
16. - Abstract
I have edited matts eye on top of his hand and his mouth on top too. I had to merge the
two images on top of each other. The mouth looks really nice on the hand but the eye
could look better.
17. - Abstract
This photo has not been edited because I thought it looked good on its own. I tried to
add filters and other effects but none seemed to work well. So I decided to leave it how
it was which still looked nice.
18. What was your favourite photo? And why?
- The eye photo because I like how you can see the brightness of colour in it
What photo looked the best after editing? And why?
- I think that the photo of Matt covering eye and mouth looks insane, it’s so nicely edited and
unique
What photo is the least good? And why?
- -The leaf photo as it looks a little too simple (for Abstract)
What affects do you think I could add to the least good photo and why?
- colour saturation as it would give it a more unique look
19. What was your favourite photo? And why?
- The eye and mouth one because it is very abstract and edited well
What photo looked the best after editing? And why?
- The rounder's ball as it looks great in black and white with the contrast up
What photo is the least good? And why?
- The gate as isn't edited in the same style as the others
What affects do you think I could add to the least good photo and why?
- Perhaps black and white and contrast the same as the rounder's ball
20. What was your favourite photo? And why?
- The one with Matt covering eyes and mouth
What photo looked the best after editing? And why?
- The eye as you can tell you took time with it and is fantastic
What photo is the least good? And why?
- The gate as it’s a little bland
What affects do you think I could add to the least good photo and why?
- Different colour to enhance interest
21. What was your favourite photo? And why?
the eye as I like the editing and it is good quality
What photo looked the best after editing? And why?
The rounder’s ball as it because it makes a common object look
strange
What photo is the least good? And why?
The tree because its colours are quite simple
What affects do you think I could add to the least good photo
and why?
Make it so the colours are different which means it is more
interesting
22. What was your favourite photo? And why?
- The eye photo because it’s a really good idea
What photo looked the best after editing? And why?
- The leaf on the fence because it stands out
What photo is the least good? And why?
- The one with the fence on its own because its quite boring
What affects do you think I could add to the least good photo and why?
- Maybe edit a bit more, experiment with the editing more
23. What was your favourite photo? And why?
Barbed wire because it only has one main focus and it was directed in the
centre of the image. Also the background is blurred out well, but also gives a
little more colour to the image, giving it a cagey tone.
What photo looked the best after editing? And why?
The eye and mouth one, because it is creative and clever, a strong abstract
photo. It also looks natural, because of how well it is edited.
What photo is the least good? And why?
The eye could have been edited further because it is quite a plain image.
What affects do you think I could add to the least good photo and why?
You could maybe change the colour of the rest of the face or maybe add an
image within the eye to give it a more mysterious setting or almost tell a story
within the image.
24. I have gotten 6 people to answer my question on all my photos and they have all had
similar results. The majority said they liked the eye photo and the eye and mouth
photo as they were both “edited well” and different. I liked these 2 photos the best
also as I think they were the most interesting.
The majority of people disliked the fence as it was quite simple, I too thought this
was the lest interesting. I did not edit that picture because I could not think of
anything to do with it. The feedback suggested that I change the colour of the image
either contrast or monochrome. If I were to do this again I would do this.
The rounder's ball and the mouth and eye picture looked the best after editing
according to the feedback. I thought these looked nice after editing however the eye
photo edited is my favourite.
The exhibition was a general success as I caught nice photos and got to experiment
with editing them which worked well. The layout of the final exhibition was slightly
different to my planned one as I did not believe the other photos I got were as good
quality as they should be.
