Absolutely without a doubt
I have done 3D renderings that were faster than Denoise 4, and I always considered that to be intensive. So yes... I definitely think Denoise 4 is way over the top for what it does.

Also.. you have nothing to feel bad about regarding your PC. My workstation core is almost 6 years old(definitely obsolete!), and so you're definitely in better shape than I'll ever be
my only problem is when Im multi-tasking. on a single photo-editing task, its not a problem. but for simultaneous and batch processing work, its too much processing for the cpu and memory to handle.

Pentax K7 ISO2500

Here's a K7 ISO2500 image I worked on for a fellow Pentaxian(Adam A) from dpreview. He agreed to let me use this image in part for an advanced noise management tutorial I've been working on(very kindly). And so I thought I would share the preliminaries with you all.

META: Pentax K7, ISO2500, 35mm, 1/60, f/5

The initial image suffered from 1 stop of under exposure, artifacts and banding(horizontal). It was processed in ACR6 and TopazDenoise v4 with intent to print full size(resolution). All in all, I'd say the final composite turned out very good. The total PP time for this image was approximately 15 mins. However, final IQ and PP times would have improved with better exposure(so next time perhaps).



PS. I'm always looking for new candidates to challenge my NR methods with, and since I've maxed out the K20D(ISO6400), I'm now looking for K7 candidates to help further develop my workflow and hopefully K7 owners. So if you are interested in helping out, please PM me so we can work something out.

JB

Dude! You chose *that* as an example?

Looks like maggots crawling over a zombie corpse!

Is that Mexican food? Not much of it here in Asia, so maybe it's just not very recognizable to me!

K-7 iso 3200

NR done. But, now with LR3 and others, it's easy to get rid of the noise still keep detail (dust on top, and the letters still tach sharp) and reduce a lot of noise.

LOL! I didn't have quite as strong a reaction, but I wondered when the photo was offered why John accepted it. I don't much like food as a subject, and this dish is less visually appealing than most. Plus the image is only ISO 2500. No offence JohnBee.

First time I've resorted to ISO 12,800 on the k-x (or anything else for that matter!) Aside from the b+w conversion there's a slight crop, resize and sharpen for web but no NR other than the in-camera setting - think mine is 'medium' for images over ISO3200.

DA70, f2.4, 1/100, ISO12800.

The gritty look goes with the pic! Have you tried cleaning up the noise? I just tried using Silkypix on an ISO 12800 pic I took recently and it cleaned up fairly nicely. The pic was in very good light however.

K20D @ ISO3200
Noise ninja used. Actually, even though I lost some detail, I am happy with these.
