I exported a photo to JPEG without realizing it had embedded Color Profile "ProPhoto RGB". When I opened it in a viewer that, presumably, assumes the sRGB ColorSpace, I really liked the effect.
How can I modify the ColorSpace metadata value so that it is always rendered using sRGB?
And is there a less tricky way to achieve this conversion? E.g., within Photoshop (or any other image editor) can I reproduce and then apply the effect of interpreting the existing image using different ColorSpace values?
