I took this shot hand held with a 40D, with EF-S 10-22 lens wide open (f4.5) at 19mm at ISO3200. I have processed it to reduce noise.

The scene is extremely dark (London Dungeon), and lit by coloured bulbs.

I was extremely impressed with the performance of the camera in such challenging conditions.

Yup, its really nice. What software did u use for NR?
 
yes, 3200 ISO with some NR in PP could produce acceptable results , most of all if you watch reduced pictures on a monitor or for small prints
 
I guess its an ok shot considering the conditions. But since you reduced the resolution so much, its hard to really judge how good or bad the original was. it would have been more helpful if you had also included a 100% crop.
 
Is there anyway to use the 40D to take images at ISO 12,800 equivalent? I seems that setting the ISO to 1600, underexposing by three stops, and processing in the latest DPP using DPP noise reduction, should produce an image equivalent to that the 50D produces in camera?

Nik Dfine2. btw, the shot was hand held at 0.3 sec shutter, so that was also a limiting factor. No IS on the 10-22 lens either :( There was just so little light there :(

Good question, and I am probably being dumb here, but would you not overexpose the shot by 3 stops? (I've never tried or considered this.)
 
No you would have to underexpose and push it up in post. If you could overexpose, you wouldn't need to!

I tried to take some pics at ISO "12.800 equivalent", setting ISO to 1600, then underexposing by three stops and processing in DPP/LR/NN (LR is best in this case), with +3EV and noise reduction. You can obtain usable result (for monitor and/or small prints) till 6400 equivalent (-2EV, then +2EV in PP), but also 12.600 ISO could be quite acceptable in some condition.
I did it with a 40D, but i haven't compared with highest ISO of 50D.

Thank you, that is what I wanted to know. I have been trying just with DPP and the results aren't so good. I thought that DPP 3.5 would be better since it incorporates the software used in the 50D to convert RAW to JPEGs.

I won't ask anyone to do the comparisons and post the results. I will just try it myself.

In my opinion the 40D is very usable at ISO 1600 and 3200, especially when downsized for the web (or printed at moderate sizes) and desaturated/b&w.

I took the following photo in a very dark wine cellar at ISO 3200, -1 ev, F5.0, 1/10s using a 40D and 70-300 lens and used a little bit of Noise Ninja is PS. I've later tried to post process the photo in LR using only the built in tools for NR and got similar results using 25/75 NR settings.

Obviously I could've had gear more suited for the job but I was called in on a short notice and grabbed what I had available... Anyway, my client was pleased and so was I.

It is a good picture. So, the new higher ISOs are achievable with the 40D! That is good to know. I am going to try more of this over the holidays and will post my best efforts. Please hope that I can do a lot of postings :)

Thanks, although a tricky assignment (due to the environment) it was very fun and I always enjoy when it gets a little bit challenging.

Just try and don't be scared for the high ISO's, as long as the shot is taken there's a lot that can be done in post to polish the results. One more tip is to use the high-speed burst mode, that way you can pick the sharpest where there's (hopefully) no camera shake or subject motion. The Sharon pic was one in a burst of five or so where the others were a bit blurry. The subject has to be quite still for a 1/10s shutter...

Good luck and share your work!

very nice pic in that low light condition and Sharon charme is still
active, thanks
