I'll try to keep this simple!

I processed a shot by desaturating from colour, adjusting exposure, contrast & brightness then added a filter to give it a slightly desaturated sepia tone, resized, cropped and sharpened.

When I save it however, whether as JPEG file or PSD file, or as Adobe RGB or sRGB colour profiles I am losing the colour from the filter layer and end up with just the desaturated B&W version of the pic!

Is this enough info for someone to be able to help?
