Proj1 - Image Resolution Assignment

Post by glegrady » Tue Jan 08, 2013 3:48 pm

Take an image post 2 or more versions. For the first version try to improve the image with the following steps:
- Image Size
- Histogram
- Saturation
- Color Balance
- Sharpening

For the 2nd image, using the above functions transform the image in an interesting aesthetic way. You could also try saving in compressed versions.

For this assignment I chose to manipulate a photo I took of my twin neighbors.
twins_before.png
Original unedited image
twins_after.png
Enhanced/corrected image

The second image has been enhanced with the following adjustments:

Image resized to 1200 x 806, resolution 300
Levels: 25, 1.2, 230
Curves: input 138, output 156
Saturation: +10
Color Balance:
Midtones: +3 red, +5 blue
Shadows: -5 cyan, +5 blue
Highlights: -25 yellow
Unsharp mask: amount 55%, radius 1.0

In order to "destroy" my third image I went back and forth between the different tools, so the steps are a bit confusing. I tried to make the image have a different aesthetic feel than a typical portrait. I'm not used to using just these features to make photos look like a deconstructed image, but making random adjustments led me to a color palette and overall look unlike what I originally intended/started with.

I used Hue/Saturation a lot and sharpened the image in order to bring out the greens and make the colors more vibrant. I'm not happy with the amount of noise that is in the "corrected" image, but I like the fact that the color of the leaves and butterflies really are enhanced. I had fun distorting my picture by resizing and saving the image in order to achieve the pixelated effect that is seen in the third image.

Original Image:
IMG_0496.JPG
Fixed Image:

Although the fixed image does not look that different from the original, I went through many modifications to adjust it.
-Resized the image
-Adjusted Curves
-Adjusted the Hue/Saturation of:
Red, Yellow and Cyan
-Adjusted the Colorbalance (Shadows and Midtones)

Destroyed Image:
DrewDestroy2.jpg
I struggled a little with this part of the assignment because my first attempts at destroying the image were not obscure enough. I found it difficult to make this photo extreme because I found these changes not very aesthetically pleasing. In order to make these adjustments I basically just played around with the different tools.
-Resize the image
-Resize it back
-Adjusted Curves
-Saturation to +12
-Adjusted Levels
-Added Gaussian Blur

This is a scanned image of a past drawing, done in pencil then ink, with visible brush strokes
Wolvo.jpg
WolvoPS1.jpg
The main goal for this image was to sharpen the blacks to look unified and bring out a traditional comic book print feel. The corrections made were:
Brightness/Contrast: 2/55
Curves: Output/36 & Input/94
Exposure: sampled a white in the image to balance color
Sharpen
For the last image I made more modifications starting out with CUTOUT in artist styles. The following modifications were:
Brightness/contrast: -82/-39
Gamma: 1.00
Saturation: +73
Lightness: 1
Midtones: -41 Magenta
