In the Appstore you can show screenshots of what the app looks like to the user so they know what to expect. I am looking into creating an image from scratch of a screenshot of an app.
Here's my question: From what I understand, apps measure width and height in "points" instead of "pixels". In GIMP I have the option of using "points" instead of "pixels" too. Should I use "points" as the unit of measurement for my canvas or should I stick to using "pixels"?
Also, are the colors on my computer screen the same as the colors on the iPhone screen? How do I make sure the colors I use in GIMP look the same when viewed on an iPhone?
GIMP mentions using different color profiles which I understand help display colors on my screen exactly the same way they would be handled and shown on the iPhone. Where I could find a color profile for the iPhone?
