I'm saving JPEG or TIFF images (in Adobe RGB or ProPhoto RGB) with the "save for web" and with the "convert to sRGB" option checked ... then after opening them in Photoshop again, their color spaces turn to "untagged RGB". What should I do for getting sRGB images from the "save for web" dialog?
You can create JPEG with 'Save For Web' and 'Save As'.
You can create TIFF with 'Save As' only
In all cases, if you want the colour profile embedded then ensure the 'Embed Color Profile' checkbox is ticked in the save dialog.
Thanks a lot ... I've just noticed that there is an another checkbox "embed color profile".
