1. GIF vs. JPEG
Between the two formats, the only visible difference to me was the separation of colors in vivid detail for the GIF. The JPEG photo simply looked blurry with not much of a differentiation of detail, more smooth than anything else.
1. PPI
Upon zooming and comparing the photos side by side, I came to the conclusion that there was no visible difference in terms of quality and/or resolution.
3. Presets
When I saved the files under GIF dithered or undithered and zoomed in, I could notice that there seemed to be more of a separation of colors. With the JPEG photos, the difference between the two was not so significant. With JPEG high, there was a little more texture and detail, with JPEG low, it was more blurry and pixelated and the colors were less distingishable.
4. Resizing
When I saved the dog image with the constraints, There didn’t seem to be any stretching that looked as though it was pixelated or downgraded in quality. Without the constraints, there seemed to be a distinct amount of distortion in which it almost wasn’t the same photo.
5. Cropping
