    Hi Guys and gals

    Does anyone know if it is possible to adjust the exposure for photo's shot in jpeg format, in PS?

    Got a few old photo's that I would like to experiment with in photomatix. Would appreciate any advice or suggestions.

    :thumbsup:

    It is possible to change the exposure of a jpg in CS2. If you go to Image > Adjustments > Exposure.... you will have a slider that you can adjust the exposure via. It doesn't work brilliantly and certainly not as well as you would be able be able to do with a RAW. No idea how well it would work with Photomatix - I guess you should just give it a go and see if it works.

    I made this HDR from 1 Jpeg:

    1.5EV either way and then tone mapping. Not as good as 3 images and I got a bit excited during the processing but I think it works well.:)

    It certainly looks good to me :thumbsup:, I adjusted the exposure 2.00EV either way on each jpeg used in the two above shots.

    @ Braiden - Those have worked well mate. I remember seeing the originals in another thread and thought they were a little dark. The HDR versions are much better and I can now make out much more detail. I really like the perspective of the path on the Big Ben shot.

    Thanks electrolyte, I think they look better than the originals too. As you say there is a lot more detail in them now and the colours also look much better.
