I just watched a webonair by Joel Wolfson on Topaz Denoise AI and it was excellent!
My question is this:
In order to batch process a number of images at once, it looks like jpeg (not raw) files needed to be brought into Topaz Denoise AI. When the processing was complete the resulting images were saved as .dng (or could be jpeg). When these files are saved and brought back into a processor like Photoshop Elements 2020 are all the pixels that were saved in a RAW file lost? ....which makes me wonder yet again if I should take pics in RAW or moved to jpeg?
Confused Pat

I watched and had the same question, Pat. I actually asked about him using jpegs and what format was the ideal for noise removal. Unfortunately my question wasn't addressed. I could see him doing this so as not to take up too much time but ideally I would think it would be better to at least use tif. files. I did try sending dngs from LR but wasn't happy with the color shift. I always shoot in RAW.

I didn't watch the webinar.
I always finish PP (using On1), then export to jpg, and finally run through Topaz DeNoise AI.

Thanks for your response, Pete. I have always heard that you should use your noise reduction software of choice at the beginning of your processing as to not increase the noise in your image. I do think that is the generally recommended advice.

I do think that is the generally recommended advice. I've read the same ... but I don't always follow what I've read and prefer to test myself. I found the complexity of converting raw files to an acceptable Topaz format then saving only to do the remaining PP not within my preferred work flow. I generally take a few minutes to apply settings using On1 to an image group and choose a very few to further process, which eliminates 75% or so of the image group.
I'll test an image or 2 running the converted raw through Topaz 1st and then finish PP.

I batched process a number of raw files thru Topaz Denoise AI 2 the output that you need to setup is not to convert the file format and will save them as a DNG and about 5 times the original file size. So yes it does batch process raw files and saves them as a DNG. However the DNG's are not true raw files. White Balance looks like a JPG, so the DNG is processed. My workflow is to process the raw file with no sharpening and then take it into Denoise with AIClear. I did test this in the BETA version.  |

Missing the white balance and the profiles on the DNG files   |

My workflow is the same as Frank's and it is the one suggested by Topaz Labs. Source: Getting Started with Topaz DeNoise AI |

The way I read Frank's process ... process raw file without any sharpening and then take it to Topaz ... which is similar to my work flow |

Interesting. I always do my basic raw setup with Elements 2020, process with DeNoise AI if needed and then edits with OnOne. In the Webinair with Joel Wolfson, he always processes his files first with AIClear before editing his images. (Helen, correct me if I am wrong).
I'll have to give this other process a try.
...at the end of the day, I still am not sure if I should stick to taking RAW files, or switch over to JPEG files. RAW files are so large.

I compared Topaz suggested work flow [raw file to DeNoise, save a dng, and then PP] to my work flow [raw to on1, export to jpg, Denoise on the jpg]
My raw file = 14.3 MB, the resulting dng = 69.6
DeNoise did read my raw file directly and certainly did remove noise (DeNoise screen capture)
Using On1 on the original raw file I did a quick PP and then copied the settings to the dng produced by DeNoise. I exported both On1 and DeNoise edited files to jpg and compared them at 100%
I fail to notice any significant noise reduction difference between the 2, but using onOn1 first then DeNoise last produced a much sharper image.
If anyone is interested I'll gladly provide the original raw file for verification.

Thanks for taking the time to share your results. Looking at your side by side results I agree with your assessment. The only thing I wonder about is if perhaps after using Topaz you might need to adjust the output image differently than you did in your original processing of the file rather than
applying the same settings?
In my own comparisons so far I am finding better results if I export an image to PS and use DNAI from there rather than going directly to DNAI from LR.

I hadn't considered changing the settings since I was attempting to keep everything the same, but you have a good point. I went back and adjusted the sliders in the On1 three filters used trying to duplicate the look ... haha
The sharpness and noise were about the same, but DNAI 1st had so color differences : bell, people, headlamp
Interesting exercise
ps - the color difference in the head lamp was imparted by DNAI in the first step.

Last check ... I promise I used On1 to convert the raw file to .tif and then used DNAI first followed by copying the settings from the edited On1 raw file.
Color differences disappeared and the DNAI first image is sharper. I think there's an issue with the raw converter in DNAI when dealing with Panasonic rw2 files.

I did a little test of my own this afternoon. I wanted to show the extreme difference I am finding when I use an arw (Sony raw) directly from LR: This is what comes back....no processing  Compared to what comes back from DNAI if I export to PSCC first: No processing  I think when I use the Topaz program for noise reduction I will go by way of PS. |
