JPEG colorspace confusion
Posted: 2017-04-01T09:35:14-07:00
Let's say I have two JPEG images
two.jpg has an explicit sRGB profile, so I assume that the data is sRGB encoded.
What about one.jpg? As I understand it, sRGB is the default so its data should also be sRGB encoded, correct?
What has me confused is that colorspace is listed as RGB in both cases.
