Sorry about all the GIMPesse

LOL

I'm sure; in fact I know there are CS2 actions that can do this too on Action Central. Believe it was Chip that created an action that does this (CSpringer). Always a lot easier to use scripts and plugins, especially if you are lazy like me.

Re: HDR exercise (Candle)

This Is a great idea and enjoyed "having a go " problem is camera limitations and i think i have exceeded them on my camera, when using the aeb in low light i am getting banding more noticeably down the left side (or top) .
I probably would not knowingly post a image with this problem but as i made the effort i will.

I got out the little tripod attached it then decided i wanted a portrait shot so stood the camera on end on top of some books to get the height wanted (tripod sticking out ) took 3 shots -2,0,+2 and then used the trial version of hdri

Answer: I looked again at the HDR thingy in CS2 and finally figured out how to merge to HDR.. I did not have enough tonal range before when I tried it.. It worked well on these images though..

As for the rest of your post... HUH? Way over my head...
HINT.. there is a tutorial section here at RetouchPro.. I would love to learn what the heck you just said.. BTW, I use PS7 mostly and CS2 just recently... my camera is a point and shoot... no RAW, but it has satisfied my needs thus far.
I would like to see a sample from you of what you are talking about in this thread using this "simple exercise" in HDR..

I think your HDR looks very good.. lots of detail in both the near and far objects

Your composition, like your art work, is superb I think it came out pretty well except for the banding.. How does your longest exposure compare to the Tonemap?


I Re-Shot my previous scene using manual, ISO 50, F8 using a bracket of 7 shots from 1/25 thru 3Sec... (maybe longer exposures, maybe up to a minuet or more, may have helped some)It's a pretty big area (4ft X 5ft) to capture with one little candle..

These have not had anything done to them except being saved for web to be posted here.. The last photo on the right is a HDR tonemap from just the one 3 second exposure(I used an older version of Photomatix for this, The newer versions need 2 or more photos to make a HDR)

3 sec exposure, ToneMap, EnhansedToneMap, 1PhotoToneMap

Re: HDR exercise (Candle)

Thank you for your kind comments OlBaldy unfortunately i cant look anything up on the images taken, because i had a "Hissy fit" when i saw the banding on the final image and deleted everything

Re: HDR exercise (Candle)

palms1..Bad Girl!

Like I said in my previous post I finally figured out the merge to HDR in CS2 thanks to Markzebra having me re-visit it.. and here is that unmodified HDR from CS2

I think a few strategically placed reflectors would have enhanced the scene greatly; but, if you are going to the trouble to get a good table top shot why the need for HDR?

An Interesting "simple exercise" Doug.. I enjoyed playing with a camera again.. It's been maybe 15 years

OK, I will Shut The Heck Up now and give others a chance

Re: HDR exercise (Candle)

Hi there,

first of all very nice images what U did

here it is my try and some of detail:

I used a Canon EOS D350 on a tripod, ISO100 at f5,6 aperture, the optimal shutter speed by the compact photometer was 2", bracketing +-2EV, the blue light created by a key chain torch, HDR created by photomatix and converted in cs2 at local adaptation corrected S curve, high pass layer sharpened.
