Default HDR (Photomatix) from the one photograph.

I have been going over some of my old
photographs, especially the contrasty ones,
to try and redeem them.

If I use the PShop CS2 curves and generate
two photos from one, one with the shadows
fixed, and one with the highlights darkened,
and then combine them with Photomatix, then
I get a presentable whole.

Has anyone used this method too, because it
saves the tedious layering process in PS.

Is there some sort of downside?

I've dropped a few of my efforts onto the web for you to have a look at:

http://www.freenetpages.co.uk/hp/nei...tos/index.html

Most are from a single RAW, letting Photomatix sort it out. One is from
a three JPGs (one as taken, one lightened and one darkened as you
outlined above).

Some photos work better than others for Photomatix. It's awfully easy to
get some very odd colours and fringes (as you will see from a couple of
the examples I've given!). I'm still playing with HDR, and as you will
see from the examples, I'm certainly no expert.

I'm not sure what you find about Photoshop's HDR that drives you to
Photomatix. You can use HDR in Photoshop with one image. Just develop
high and low, save as TIFF files and use them. I frequently do it when I
need to recover blown highlights.

I used photomatix to recover old photos (both digital or scanned
photos) and convert into HDR. Check them at
http://picasaweb.google.com/aniramca/Photomatix_HDR
All photos come from a single JPEG file, or scanned from a print into
JPEG file. I usually create duplicates using Gamma correction in my
old Paint shop Pro version 6 (or 7?). I made 2 under exposures
(usually with gamma = 25% and 50-60%, and 2 over exposures (usually
gamma = 190-200% and 360-400%).

Thanks, this is what I had in mind. I
photograph buildings and this produced high
contrast when the sun is shining.
Normally I wait for an overcast day to get in
all the detail, but this method might save
some trouble.

DxO Optics Pro v4 has some form of
optimization, but I do not know if they use
this one.

I have not yet tried the one in PS, but I
will.

Even that is not necessary. Just use Photoshop to convert the RAW image
to a low contrast (say -30) 16 bit Photoshop file, making sure you get the
whole image into the more or less linear part of the curve. Make sure you have the
whole high and low parts unclipped. 16 bits is plenty to get any image
from current cameras, even the newest "claimed 14 bit" Canons, if done right.

Save the original. Then go to work in Photoshop. Use Noise Ninja on the dark parts.
