Top 10 Mistakes In HDR Processing

July 24th, 2010

I was watching The Tech Guy podcast this afternoon and was please to find that Leo had Trey Ratcliff from on the show. For those of you that don’t recognize Trey’s name, Trey is one of the top practitioners and spokesmen for HDR these days. His work is very popular and he wrote the book,  A World in HDR. If you’ve not heard an interview with Trey before you can listen to the whole interview by subscribing to the Tech Guy Labs Podcast on iTunes or you can download the audio directly from the Tech Guy Labs site sometime next week.

Trey mentioned that he just recently released a new e-book on the Top 10 Mistakes in HDR Processing. God knows someone needs to write on this subject, who better to do it than Trey!

This E-book covers all the deadly sins of HDR from Halos, to Dirty Whites to radio active colors and shows you how to fix these problems.

I highly recommend this e-book! If you are using HDR for real estate photography I think studying Trey’s techniques are a great way to polish up your sensitivity to the pitfalls of HDR. Trey does great HDR but is very aware of the potential excesses and how to control them.

I think if you are into using HDR, looking at Trey’s work is valuable. While not all Trey’s work is appropriate in the real estate context, I think he has a good sense of where the HDR boundaries are.

  • I am sure this book is pretty good. Well, e-book that is. Have you bought it? I probably will because of wanting to see how it compares with my work.

    I believe that the more you do the work, the better it gets too. Just like the more you take pictures, the better you get. The more you process your HDR images the better you get. Once I realized that you don’t need to limit yourself to that tonemapped image, it started to change everything. But I wouldn’t have realized it without the time and practice. Even if I was to read something like this, I may not have understood it without time and practice still. It’s weird but true.

    It’s constant progress and that’s why I can’t really rip on the stuff I see on flickr sometimes because I don’t know where they are at in their journey. Many people want the quick information like this but then don’t take the time to experiment with how or why it’s needed.

  • Didn’t learn a lot from the e-book I didn’t know about HDR problems. My bigest are:
    1. It does too much with reds.
    2. It dirties whites.
    While masking/layering techniques for sure can help; they are time consuming. My preference to fix both is to use Photoshop color sliders – simple and pretty effective. I also like and use Topaz Adjust.
    For all its problems, HDR gives great results my agents come back for, time and time again.
    The very best complement is when an agent, after many photo shoots, asks me to shot their own personal residence. Then I know I’m doing a good job.
