Hi,

I have Topaz DeNoise and I am trying to get the best results and I am having really hard time. I have lots of images shot in dark room ISO 3200, very noisy and I am trying to use Topaz DeNoise but I am having hard time getting really good results. Does anyone have their "favorite" settings that can share for Topaz DeNoise. I would greatly appreciate it. Thanks!

For really high ISO's I usually use the "JPEG strong" preset. For most other shots, I use JPEG moderate, and tweak the sliders a little. This pic of ' . substr('//www.dpchallenge.com/images/user_icon/user_id/3102.gif', strrpos('//www.dpchallenge.com/images/user_icon/user_id/3102.gif', '/') + 1) . ' Alanfreed was shot in a dimly lit bar at 3200 with my G11 and it cleaned up acceptably, though far from perfect.

If you can post a full size image, I'll take a crack at it and tell you what settings I used.

For very noisy photos you are probably not going to get something too clean. But I find that what is good is to use Topaz Denoise and then convert the photo to black and white or sepia. The little bit of noise left can make for an interesting photo.

' . substr('//images.dpchallenge.com/images_challenge/1000-1999/1342/120/Copyrighted_Image_Reuse_Prohibited_935525.jpg', strrpos('//images.dpchallenge.com/images_challenge/1000-1999/1342/120/Copyrighted_Image_Reuse_Prohibited_935525.jpg', '/') + 1) . '

What kind of result are you trying to achieve? I always use denoise and then detail in tandem for the best results.

I can't convert to BW, has to be color. I don't mind grain, I just want to remove noise

On Denoise? I can't remember, this was quite a while ago.Probably RAW Moderate with extra denoising in the blue channel, that sounds about right for me. But my image wasn't underexposed, that's critical. The more you underexpose, the more you have to live with noise. ISO 3200 underexposed 2 stops = ISO 12,800; basically, there HAS to be noise...

Like colorcarnival, I find DeNoise then Detail to work wonders on images. But that starts with a good helping of DeNoise. My main starting point is:

Main slider around 0.1. Higher for extremely high ISO (as 3200 I would like be looking at 0.25 to 0.3)
Highlights slider moved negative to recover details
Switch to red/blue channels to adjust those sliders up or down to denoise or recover details
Color correction around 0.1 to 0.2
I never touch the correct black level
I normally set the recover detail slider around 0.5 to 0.12
The reduce blur I set around 0.3 to 0.45 (to me, this is the key to making sure you still have good details)
Banding options only used if there is visible banding

Here is a before/after example:

Bear Thanks, I am getting decent results

Thank a lot for this

I shoot exclusively in RAW (Canon 50D).

One of the folks at Topaz commented that you should use DeNoise before editing an exposures/colors, etc. That has me confused because...

a] I need to keep EXIF data for a couple of competition sites (and for learning purposes).

b] If I want to process RAW images, I have to start in DPP (Canon's program), before moving the "converted to TIF with EXIF" files over to PSP or Elements 9 for any further editing/treatment. My Topaz filters are connected with those two editors as Plug-Ins ('file locations'). If RAW are opened in PSP, then saved to TIF, all exif is lost.

c] Topaz filters can't be used through DPP.

This comment feels as convoluted, but it represents my confusion. So... how can I possibly use DeNoise first? I haven't asked the Topaz community, which would have been smart.

Just wondered after reading this thread if any of you had seen that advice before. Thanks, Kathy

I expect the advice Topaz offered you is based on a assumption of using Photoshop. They may also be taking a prior RAW conversion as understood.

I have not seen such advice, but I do use the same workflow as you do: DPP followed by PSP X2. I do my adjustments in DPP, exporting to a TIF or JPG, then opening in PSP. The first thing I do in PSP is levels, and then Denoise. Levels is first, because if the image is flat on either end, then stretching the dynamic first will give me a better idea of exactly how much NR is needed. I do use Denoise before anything further, because most other adjustments (especially other Topaz plugins) will bring out noise grain, especially in skies.

Added: I do still ocassionally use PSP's built in noise reduction in basic editing, because it has the ability to apply NR to a limited color range. It's not selective, however, making it a basic legal way of smoothing skies without killing detail elsewhere in the image (unless there are also large blue/cyan areas in other parts of the scene).

I'd assume that advice applied to those who are working with JPG originals; I don't think it's relevant to RAW originals. And it makes sense for JPGs, a LOT of sense. Translated into RAWspeak, I'd read it as "As soon you get the image out of RAW and into your photo editor of choice, determine how much DeNoising is needed, and apply it first."

Fusion works quite well in Aperture, especially with the latest update. Previously it had to be setup as the external image editor, which caused you to have to go into the preferences to switch to a different external editor when needed. But the latest update made Fusion a plug-in so you can have your main external editor setup and still run Fusion easily.
