HDR - 1st Attempt
Jun 22, 2007

I've been playing around with HDR Photomatix and trying to follow some of the tutorials posted here (Pandora1). I'm thinking that I just don't get it. This is a single RAW image saved at 5 different exposure levels and merged to HDR. Played around the detail sliders and then added a gradient map and brushed back in some lighter areas. Although it does have more dynamic range than the original, it doesn't seem to have that painterly artistic effect that I've seen in other examples. What am I missing or do I just need to continue with my experimentions?

Hi,

Give it another go but this time save your RAW files as uncompressed TIFF files so you don't introduce any artefacts. As it is a single RAW in my opinion there is little point of modifying the exposure more than +1 -1; I normally do 3 exposures from a single RAW being -1 0 +1 .

Try that and see what you can come up with.

Cheers
Jamie.

Thanks Jamie for the tips. I resized the raw conversions before merging to HDR so that could be a source for the noise like you suggested. I'll play around some more.

I'd like to see what you come up with after a second run... I just bought Photomatix and have been experimenting also, with little success compared to some of the creations I see out there.

Your shot looks great, can't wait to see what you come up with

Hi Christy

You've created an interesting image. The image itself is well composed, with the fence at the right.

Would you mind posting the original? I'd like to run it thru my HD program, Dynamic HDR from Media Chane and see how it compares.

Cheers
Steve

I also think Tone mapping of an HDR image works best when the image doesn't have too much detail. Your image has so much d├ętail that the final rendered version looks a bit like a mess. Not every image can be treated the same way.

If you want some painterly effect for this particular image, instead of tonemapping you should try to go with the Illustrated Look, maybe (do a search on the forum for tutorials).

Your image has an interesting "oil painting" like effect. It looks great if that's the look you are trying to achieve.

I've only experimented with HDR a few times. I've found working with RAW gives me better results as opposed to jpeg. I'll have to try working with tiff as mentioned above. Also, I found no difference between using 3 and 5 files. Both gave me the same result using +2 0 -2.

If you don't mind, I'll post my latest HDR workings with Photomatix. (I haven't bought the software yet)

2nd Attempt
In reply to PhotographyBB, Jun 22, 2007

Here's one I did quickly this morning using Jamie's 3 exposure TIFF suggestions. I'm a little happier with this second attempt as there isn't quite as much noise. I think I oversharpened on the first attempt as well. I'm not sure about the appropriate levels on the Tone Compressor either and need to learn some more as to what that is exactly doing. At any rate, here's the second go at Photomatix:

I hadn't considered that an image could have too much detail so thanks for pointing that out. Thanks for the hint about the Illustrated Look tutorial. I'll do some searching.

Thank you very much for mentioning the CSpringer Illustrated look. I used those ideas/steps with this third attempt and its getting closer to the result I'm looking for. This is way too addicting!

Hi Christie

Below is my try; I think replacing the sky with a nice blue would really set this off.

Cheers
Jamie.

Excellent Jamie. Your colors look much more natural and true to life. We just need to do a little work on the blown sky to pull in some blues like you suggest.
