Hello,
Today I bought the Canon 50D and I have a question:

What about the setting of High iso speed reduction?
Standard,low,strong or disable
which is the best choice?

Thanks

I shot raw & have it disabled.

Hi Manos- You are a lucky man! I have the 50D on order but it has not arrived yet.

I think you are asking about High ISO noise reduction. I do know that at least on the 40D, if you set this to on it will slow the camera down a lot.

Personally I would set it to Disable and reduce noise outside the camera.

I have it set to Standard and I've not noticed a slow-down. I think it does a very good job if you shoot JPEG. The high-ISO images I posted on the Avian forum were all shot JPEG with high-ISO NR set to Standard. Try it both ways and see how you like it.

Thanks a lot Doug and Renate!

Manos,

I shoot large raw..up to ISO 800 it's pretty good. I tried the NR with DPP & Noise Ninnja & Neat Image which are pretty good..but this does an even better job

I was asked a question about high-ISO NR by another forum member, and I thought I'd post my reply to him in this thread:

"This is a good question. Here are a couple of links to help answer your questions.

http://www.dpreview.com/reviews/canoneos40d/page19.asp

http://www.usa.canon.com/uploadedima...ings_Final.pdf

I suggest that you read both links. The short answers are:
1. Long-Exposure NR works on images with exposures longer than 1 second. It is completely different from High-ISO NR.

2. High-ISO NR is applied to photos shot in the JPEG format but not the RAW format. However, the NR is applied to the JPEG embedded in the RAW file. When reviewing RAW photos on the camera's LCD screen, you'll see NR because the camera displays the embedded JPEG. But when you get home and look at the RAW images on your computer, there won't be any NR applied to the RAW images.

3. High-ISO NR is active across the entire range of ISOs, and can be beneficial even at lower ISOs.

Hope this helps!

Regards,

Doug"
