Some manipulation fundus photographs!

Fifth draft animation

The 4th attempt was nearly there, so this 5th version is just an improvement on that:

The sharpness was increased and the contrast curve altered to better bring out the details.

The colours were reworked, trying best to match the colours on a downloaded image of Jupiter .
Jupiter Colour Guide
The Turbulence Displacement type was changed to a twirl effect and increased slightly to better emulate the twists and turns of the clouds of Jupiter, still without destroying the original forms of the images too much.

Another type of warp was added to make the images bulge in the centre as they move across, which further increases the impression of planetary rotation.

The images were layered a little differently over time to provide more interaction and to slow down the transitions without increasing the overall film time too much (it has only increased from 80 to 90 seconds). The sounds were layered slightly differently to accommodate the change in length.

Eye and similarity to moon!

Forth draft animation

I used 7 images for this animation.
Idea: Take all the things that worked from the other drafts while removing all the things that didn't! Also, I wanted to stay 'on message' with the concept, now I understand it a bit better. Most of the techniques used in this video have been used in previous drafts, but in different ways and different configurations.

Form: In the second animation draft where I tried to emulate the forms of the planet, with the spot and the line clouds , didn't work and looked really cheesey. The photographs already have beautiful forms, but they don't have colour or movement, so I decided to add colour and movement to reflect Jupiter, while keeping the forms of the original images.

Colours: After sharpening and applying a contrast curve, the photographs were coloured. The three major colours of Jupiter are beige/brown, white and dark red. The colourless photographs were recoloured to match those: first, the whole thing is 'colourized' to beige/brown; the high-luminance parts were then recoloured using 'Change to Color' to make them white and washed out (I also slightly changed the hue to a purple that seemed to fit well at the edges of the spots). Likewise, the very dark parts were recoloured to red.

Movement: Each photograph moves slowly horizontally in the frame, behind the circular clipping mask, to emulate planetary rotation. A subtle liquid effect is applied to give the surface forms a little bit of movement, like rolling storm clouds--the effect used was 'turbulence displacement', set to warp only vertically. Each image layer is staggered over time and the opacity animated, just like in all the other videos; however, the blending mode was change to 'Exclusive' (instead of 'Screen') so the images interact with each other in more interesting ways during the transitions.

Sound: The animation is about 1min and 20sec long.The original sound from NASA is only 45 sec. I asked one of my friend who is an Electronic music composer to make it one long sound that matches the video length and positioned so the intense parts of the sound match the intense parts of the video (large white sections).
The Jupiter sound wav file from the NASA website was looped and crossfaded (i.e., the end of one loop blends into the beginning of the next loop) .

Third draft animation

I used 14 images of right eye for this animation!
After the feed back I received from my tutor and the other students over the second draft I decided to experiment further and use some of the effect in a slightly more subtle way rather than force the eye to look like Jupiter.

Second draft animation

These are the images I used to make this video,I picked these images from the same series for number of reasons:visually they show the noticeable change in eyes during the angiograms procedure , from the making animation point of view they had a strong dark dot and also these ones seemed crisp.

What I did to make this video:

  • Layered the four images on top using the 'Screen' method of blending (just like you might in Photoshop)
  • Animated the 'opacity' of each so that they fade in and out of each other

[An 'adjustment layer', in case you've never used one in photoshop, lets you apply one or more effects to every layer below it, without having to apply it to every layer or merge the layers to one image first]

  • Added an adjustment layer with a colorize effect to make the light- and mid-tones brown, and another to make the dark tones red. Then I animated it to increase teh colorization over the course of the video.
  • Added an adjustment layer to 'warp' the video, to emulate the movement of clouds on the surface. The bands were done by manual smearing, and the effect around the dot was done using the 'twirl' effect. Both were animated over time, like above.
  • More adjustment layers were added to alter the hue and lightness, using masks to isolate areas and create the bands of white and red. Again, this was animated to fade in.
  • Finally, the image was cropped into a circle using a black solid and an inverted mask.
Here are some the screen shots and diffrent things that i did in the second draft:
Warping: The movements of Jupiter's clouds was drawn manually using a mouse and the distortion amount increases over time. The twirl effect was added at the eye. Both move around a little to best fit the current photograph.
Main Colouring: The grey images are recoloured using the 'change to color' effect to make it brown and red.
Colour Bars: The rings of the clouds were added by adjusting the hue and saturation of selected portions of the video.

Format type:

I rendered the video to the uncompressed format first to keep the highest possible quality although This gives maximum quality, but the file size is huge so I have to change the file to the a compressed video, instead of storing every frame as a fresh image, just stores the differences between frames and does a bit of clever manipulation to reduce the file size at the expense of detail where changes are subtle A MOV file is actually a 'shell' for a video. Most kind of video formats can be put into a MOV shell. The codec I used to compress this one is called H.264.
