    Topaz DeNoise practice

    I'm getting a little better now at using the slider adjustments, both gross and fine, in DeNoise. I'm also getting more comfortable determining which of the 4 general categories might be better suited for any pic I import, before I even see the 4-way comparison screen. The more I use it, the more happy I'm becoming with it. Not so much because I'm such a geek about post processing, but because it's gonna be a long while before I can afford a longer lens to do bird photography. With DeNoise, I'm starting to get a bit more adept at cropping a fair amount without introducing too much noise, and at the same time maintain or even enhance sharpness.

    Here's an example. This is a practice shot I took a for this week's "Leading Lines" challenge:

    Topaz DeNoise practice-guy-app-trail-1.jpg

    This is the shot run through DeNoise:

    Topaz DeNoise practice-guy-app-trail-dn-1.jpg

    The difference really becomes apparent though when you crop heavily. Here is the first (non-DeNoised) pic cropped down to just the guy:

    Topaz DeNoise practice-guy-app-trail-detail-1.jpg

    And here is that same crop applied to the DeNoise processed pic:

    Topaz DeNoise practice-guy-app-trail-detail-dn-1.jpg

    The difference in noise levels between the two is dramatic to my eye. Details are enhanced in the hat logo, the backpack straps and bag, the cargo pants particularly, the wire fence in the background, and the walkway. Basically, everything. So while it may not be as apparent in the larger non-cropped pics, I'm really looking forward to seeing if this same effect can be achieved in my BIF photos where I have to crop heavily because my longest lens is 300mm. Wish me luck!

    Sharpness improvement is visible in the un-cropped images. Yet the improvement in cropped images is surprisingly impressive.

    Spent a day yesterday at the Space Farm animal sanctuary and museums yesterday and came home with a ton of shots. First time I really got to try BIF photography for any length of time, in addition to all the other things to shoot. My god, but that D500 is a joy to shoot with. Aside from everything else, I'm really impressed by the dynamic range improvement over my D5500. Inside the museum buildings the lighting was very poor - in some cases, even non-existant with only high window lights, creating insane contrasts between stygian darkness and glaring sunlight above. But that D500 had no problems keeping everything in the happy range of the histogram.

    I'll post more in the coming days, but I just wanted to post this now because I'm trying to decide whether to enter this shot, or the hiker shot in the previous post, as my "Leading Lines" entry:

    Topaz DeNoise practice-line-cars-2.jpg

    This one wasn't bad either, but perhaps not as dramatic:

    Topaz DeNoise practice-line-cars-1.jpg

    Again: decisions, decisions....

    Both the car and hiker images are excellent - I noticed you went with the hiker. That would have been my choice, too.

    @Dangerspouse I noticed your DeNoise images are at ISO 200... In DeNoise, there's a "sharpness" slider... How much are you adding with that slider?? I imagine the "enhancements" you're seeing is more a function of that "Sharpness" slider than any actual noise reduction at an ISO of 200

    Hi Fred. Thanks for the input.

    I rarely use the Sharpness slider. Only occasionally in the 4-way comparison screen, making all 4 the same mode (Low-Light, Clear, etc.) and moving the sharpness and Restore Details sliders around so I can compare how the different levels look. Very often, most times really, I find the program's AI does the best job and I leave it as recommended.

    Such was the case here. I didn't adjust sharpness at all. I think perhaps in retrospect this may have been a poor example to post because this particular picture has so much fine detail that everything was perceived as noise, and so over sharpened as part of the processing. More sharpening than I may have done in Lightroom alone, certainly. I imagine that had all the foliage in this pic been a body of water or some other more-or-less homogeneous expanse, it would have been a better showcase.

    I agree wih Cindy that you have made the correct choice for the 'Lines' entry, however I love the cars, especially the second one with colourful wheels

    Isn't that great? If I recall correctly, that particular vehicle was a very early pickup truck.

    I have no idea if this is relevant to today's Denoise software, but years ago I watched a video that suggested applying any sharpness should be the last thing you ever do to a RAW image. In fact the person advising this went on to say he never sharpens his images in Lightroom but left it until after he exported them to another program (it was DPP, which is a Canon software program). I just got into a habbit of doing the same thing and on the few tests I carried out myself I thought there was a minor benefit in doing so, although probably not that noticeable.

    One problem with sharpening before resizing is that downsizing over-sharpens an image...actually quite a bit. Many times that leaves an image looking extremely crisp (for lack of a better description). I believe BackdoorArts has also mentioned performing sharpening last.

    I haven't used DeNoise, but in Lightroom and Camera RAW, there is an option to mask under the sharpening tab. It is helpful to use it so only the details get sharpened, not everything in the image.
