I've seen many rave about Adobe Photoshop, but I'm still on the fence considering a purchase. Anyone care to take a stab at processing my latest M33? I'd like to see how much a difference it makes. The full size .jpg is here
Thanks,
Sean

Ya we need a crack at the Tiff Stack to really do it justice but I have seen people do great things with Photoshop or Iris or Pixinsight along with other programs I think it just depends on the difficulty level and how much you want to spend.

a'right...I'll post the .tiff tonight. It doesn't seem quite "red" enough, but I definitely like the gradient reduction. Looks like it lost a little detail, hard to tell from the small size. Do you guys want a raw stack out of neb? That is, unstretched full spectrum?
FWIW, I've tried IRIS and had a really difficult time with the stretch in IRIS (asinh)...finally just gave up. The registration is nice in IRIS though. Neb seems to have a much finer means of stretching and scaling...but I could be just missing the IRIS boat I suppose.

Here is one with a little work on the JPG. I am sure we could get a ton more with the tiff as you obviously picked up a lot of information in your image! This is an incredible shot!

Make sure the .tif is just a stacked version, not one that has been post processed with an image editor. (that will make a difference too)

ok...here it is M33HIRES . It is stacked in Neb, nothing else. Darks and flats applied prior to color conversion. Thanks in advance. I very curious to see how it turns out. This is 15x5min subs with a 10" f/5 newt in pretty dark skies. Should have a ton of detail.

Ion101 - Your adjustments are wonderful.
Would you share the workflow/tools you applied in PS?

yea, playing with jpg's doesn't help much. Here is the tiff after I spent about 45 mins on it playing around. I have to compliment you on the capture, it is really good with tons of detail. Was a real pleasure working on it. Hope you like the results...

Opened the image, stretched it with curves, did a color balance adj. - used gradient X terminator - another curves adjust - another color adjust - reopened original image - layed it over and made a layer mask to bring back the bright areas - flattened image - increased saturation - pulled out a better exposure balance with the shadows/highlights tool (set final black point) - used Noel Carboni's "Deep space noise reduction" & "color blotch reduction" saved it out

You have some super data here Buhlig its wasnt hard to get it look good and I could have done a few simple tweaks and been happy but I kind of went as far as I could just to see what I could get out of using Photoshop.
I guess I went a little bluer then David did but thats easy enough to fix , its all personal taste.
I kind did my standard routine of a run through Nebulosity for the DDP which was a little darker then my subs come out but I usually stack in DSS.
First ran a couple more curves and then I set black points in levels in each channel.
I ran GradX like they recommend on there web site and croped it down a bit.
Then reset black points again in each channel and then using curves and ctrl click on the darkest points and brightest points and then using arrow keys to adjust I was able to pull some detail up.
I did a high pass filter layer to sharpen then did a inverse mask as shown on the light buckets site with noise ninja and a color boost with match color.

I really like Nils version, makes me consider getting Nebulosity. Although I think most of the work flow was in Photoshop, the high pass filter especially makes a difference. The only thing was maybe he could have pulled out more of the Ha nebulosity to made it redder.

I'll try to convince you that you don't need PS, but need PixInsight instead. Much cheaper and much more powerful and focussed for astrophotography works. I would have liked to process it from the very beginning though.
Steps:
Gradients elimination with Dynamic Background Extraction
Histogram stretch
Dynamyc range compression with HDRWavelets
Tiny noise reduction with GreyCRestoration
Color saturation with curves
