p.1 #1 · High ISO noise reduction, RAW and 5DII

Hi all,

Haven't tried it yet, but does the High ISO noise reduction custom function work on RAW files in the 5DII and does that raw file change show up in Lightroom?

Also, is it worth using that function?

Thanks in advance,

Joseph

I believe it only affects JPEG's, not RAW's. If you want to see the affects with RAW's, you have to open the files up in DPP (canon software).

That's the way I understand it also. Either way I have it turned off because I'd rather process my own noise rather than leave it up to the camera. That's why we shoot RAW... Also, at least on my 1D3, having it on even when shooting RAW can increase in-camera file throughput therefore increasing the LCD display time and reducing the capacity of the buffer.

Thanks,

I also like to process the images myself. I was just wondering if anyone found it useful/better than what they could process. Good to know that its not. And I'd like to have the largest buffer myself. Shot some indoor arena hockey yesterday and it was difficult due to horrific lighting conditions but the files still came out wonderfully.

Love the camera, and the AF isn't anywhere near as bad as people are making it out to be.

It'd probably come in handy for professionals that are more worried about workflow, they will shoot in JPG and upload directly to their newspaper editor or whatever. In that case, a little noise reduction in camera would help.

I did some testing and found that the in-camera NR for JPEGs is better than what I can do to RAWs in Lightroom:

But I imagine you could match or beat the JPEG NR by using Noise Ninja or some sort of fancy filter workflow in Photoshop.

If the 5DII is anything like the 40D, the in-camera NR might take a lot of skill to duplicate using NN or NI.

I shoot youth sports in jpg, and the ISO3200 results I get out of the 40D with in-camera NR enabled are noticeably better than anything I can get on my own without it. I don't shoot Raw, but I have the feeling that if it is possible to get better results that way, it will take me a lot of practice to get there. I just don't have the time, and the jpg results are just fine for my purposes.

That's definitely encouraging. I'll have to try it at the relatives' house on christmas. Very cool.

I might have to try that as well. I'm excited. Perhaps Canon has a few tricks to decipher the noise from its sensors that we don't know about?

My findings concur with those above. The in-camera NR (which is duplicated in DPP) is generally better than what is possible in ACR, though not quite as good as what can be achieved using Neat Image.

I used to pooh-pooh using this, but I have come to realize this can be quite useful when workflow efficiency is important.

In RAW, DPP can be set to respect the in-camera NR setting. This causes chroma and luminance NR sliders to bet set based on the ISO setting of the file.

Note that even if High ISO NR is set to 'disabled' in the camera, both the camera and DPP still apply a minimal amount of luminance NR ('2' on the slider). Most of the time this is okay, as DPP's '0' conversions are both noisier and sharper than ACR. But if you are doing NR using another tool in post, you'll want to set the sliders to '0' in DPP.

I have posted a few shots on my web page. The first thing I wanted to do is try to recreate the black dot problem. So i shot a christmas tree with lots of lights. I can see some black spots but they are very very hard to see. To me it is not much of a problem. The second shot is of a stage performance of singers and a band. This shot was taken only with stage lighting at ISO 1250, handheld at 1/60th. You can view both shots at the original size by clicking on the original button on the right side of the page. Here is the link.
