  • JPEG vs raw

    Re: JPEG vs raw

    Thanks John. That is a very convincing demonstration of the benefits of using raw.

    I have found that as a last resort 'Shadows/Highlights' can go some way towards rescuing a JPEG. I hope you don't mind but I tried it quickly on your JPEG image. I had to desaturate the colours slightly afterwards. Obviously it is nowhere as satisfactory as the raw image but is it an improvement over the original? I have no idea what the original colours were like.

      Still not right - you haven't removed the name on the camera strap!

        Olybirder - don't mind at all. That looks like an impressive result, I'll try shadows/highlights on the full sized version and see how much it digs out.

        I noticed the burnout at the time and shot again with -1.3 stops compensation. I haven't done the same forensic analysis on that one (not enough hours in the day) but at a quick glance we still had some burnt-out highlights, and had lost shadows as well.

        Jim - I wondered how long it would be before someone spotted the strap!

          Following Olybirder's suggestion I have just had a little play with the original using shadow/highlight adjustment on the JPEG. I don't normally think of it, I habitually do all adjustments using adjustment layers and Shadow/highlight is not available there. It certainly produces a more natural-looking result than just using global exposure or levels adjustments, but it leaves the burnt-out patches as they are.

          By the way, I updated ACR to 6.7 this morning so was able to compare the recovery between PS CS5/ACR 6.7 and LR4.1/ACR7.1. The extra refinement that you get with the highlights and whites sliders in ACR 7 allows much better recovery than the single recovery slider in ACR 6. The samples above were done with LR4.1/ACR7.1.
