In a project I often use a colour board plus a photo as a means of displaying text detail associated with the image.
With 1 exception, that's worked fine. But I've come across a combination where the colour board - yellow in this case but I tried several including white - washes out the photo image over-laid on it. Screenshot - gong 1.
I've tried colur fixes and different colurs as the board backgriound to overcome this wash out effect, but eventually I resorted to just a blank background and white text: wash out fixed: screenshot - gong 2.
In the gong 2 shot note that radically different - but normal, the way the photo was shot - appearance of the overlaid image: not washed out, and no special effects applied in PD18.

Which seems to me to be a kluge solution - not one generally reliable upon.

Is there any way to avoid this wash-out effect of the colur board background on an overlaid photo??
