Raw files seem to have noise Hi everyone Well, I have done a search of BP and can't seem to find an answer, so I am hoping you can all give me a heads up. I just shot 3 weddings on the weekend, and it all went well. It was my first attempt at shooting raw, and although I love how easy it is to adjust the photos (especially when brightness range was 5 stops etc), I have noticed that the raw files (converted to Tiff to edit) are quite noisy, compared to when I was shooting in Jpeg, what is the best way to reduce the noise? This is happening on all the photos, regardless of ISO (obviously more noise on the church photos at ISO 800), My workflow is: Download all Raw files Should I be adding a "reducing noise" action in there somewhere? Cause I never needed to do it when I shot Jpeg. Does anyone else notice that raw files are more noisy than Jpeg, or am I doing something wrong? Your help is greatly appreciated. Thanks.

Hi Natalie. JPEG's are processed in camera thus reducing noisy, however, at iso 800 JPEG's are noisy. When shooting RAW at iso 800 you would expect lot of noise. You should use a noise reduction software or the build in noise reduction in CS2 first, before doing any adjustments to the image. I use noiseware. Hope this helps. k.

Hi Natalie - I hesitate to respond to your post, I’m in no way in expert on this; however, since switching to RAW I have noticed pretty much the opposite of what you experienced. I generally shoot at an ISO of 100, but when I do push the ISO up past 400 or even as high as 800 I have not noticed any appreciable noise. I use a Canon 5D if that has any relevance. I do know, according to my reading, that it is often necessary to sharpen digital images especially those taken at higher ISO ratings. I use PS CS2 and use the “Smart sharpen” tool which I like better than the unsharp mask, which, in my experience added noise to the images. I have no experience with batch sharpening and do not know if this would affect the noise issue. I’ve noticed that my RAW images often end up looking a great deal sharper and clearer than my Jpeg images. I suspect this is because I have better control over the final image result. One final idea is to try “noise ninja” http://www.picturecode.com/ which I have heard does a terrific job of reducing/eliminating noise. I hope that someone else, with more experience, will also answer so that you can get better feedback. Irene

Hi everyone, Thanks for your response. I worked out what I was doing wrong, I wasn't adjusting the raw files properly before I converted them to tiffs, I didn't realise in CS2 Raw converter there was the second tab where I could smooth the image and reduce noise, images are far better now, so unfortunately, I have to now re-edit quite a few photos, but that is ok, at lest I learnt earlier on, and not after a few weddings. I am finding the editing side of things a lot quicker in raw than in jpeg mode, so yes, loving raw as well. Just a question, once you have done as much editing in raw converter as you can, do you then convert images to tiff and open them in CS2 to do any final adjustments - cross processing, hand colouring, dodging/burning etc? as that is what I am doing. Just wanted to know if my workflow was right. I also do batch processing in the tiff mode. Ta

Hi Natalie – I am glad that you managed to find the solution to your problem with converting your images without adding noise. If you have not already read it, I highly recommend Rob Shepherd’s book on shooting and processing RAW. I’m sorry, but I am not home at the moment and cannot remember the full name of his book. It has helped me very much with trying to learn RAW. He suggests that all sharpening, color adjustments and such be done once the image is brought into PS and not in the RAW converter. I have found that this works much better for me and results in a sharper image with less noise. Incidentally, I’ve said it before, but I’ll say it once again; you have a remarkable gallery!

Thanks very much Irene, I much appreciate your feedback, I will try and find that book, as I haven't really had much guidance on the best possible way to process raw. Thanks for your comments on my gallery too! much appreciated, although I much prefer my new website now.
