Although Xcode image compression is better than nothing, the “CgBi” images are larger and slower than well optimized, standard PNGs.

Disabling Xcode conversion and simply using ImageOptim instead was enough to reduce the application size by almost 30% (33.4MB down to 23.8MB) and halve initial display time in the benchmark.

Manually optimizing images with ImageAlpha reduced entire application size by more than a half (33.4MB down to 16.3MB). Images alone were 65% smaller and were displayed 2.5 times quicker than Xcode-optimized ones.

Since Xcode conversion can be disabled and iOS supports standard PNGs, such big size and speed savings are possible in actual AppStore applications.

TinEye is a reverse image search engine. It finds out where an image came from, how it is being used, if modified versions of the image exist, or if there is a higher resolution version.

En fin samling tips kring digital bildbehandling och fotografering. Mycket matnyttigt att läsa.

En mycket bra samling "tutorials" kring digital fotografering och bildbehandling. T.ex. hur man använder nivåer och kurvor i Photoshop, men även grundläggande om färglära, vitbalans och mycket annat.

En mycket intressant teknik för att göra ett webbinterface för att beskära bilder. Något att bygga in i ett bildhanteringsystemet t.ex.
