l got the files from We transfer. l like PS the most. Even though Dfine reduced noise more, it seemed to smear details.
Any time you use noise reduction, there is a softening of your image. It doesn't work with all images as you would like and typically, you have to alter the image a bit in a package like Photoshop to make it as presentable as possible. If you are tiring to save an image, these are your best choices and used as a last resort ... better something than nothing .... but I would not make a habit of relying on them to "get the image", so to speak.
In your example, you have chosen to crop it at 100% and the editing is really obvious. I think, if you were to do a 4x6" postcard print, this would not look too bad if this was a keepsake image you had to have. If it was something you wanted to crop for publication, I don't think it would work.
I have attached a 4x6 image below just as an example to this comment....
In my opinion, if you have night shots like this of an important event, this is a fine image for remembering something of importance. It beats having nothing at all, so the tools are quite helpful in certain situations in saving an image.
If your goal is an artistic capture, then techniques and/or gear have to change in order to capture the moment.
I am NOT a Lightroom user. I can't stand Adobe and have refused to ever learn it. It may have a better Noise Reduction Tool, I don't know. Maybe someone with Lightroom can take a crack at it for you. I own LR 5 and just couldn't wrap my head around it. My philosophy was:
I have Nikon gear
Nikon makes software for their images
What better software to use than the one made by the manufacturer who knows their own code
So, I went with Capture NX-2.... which had to be purchased at the time
--after the NIK fiasco, Nikon rapidly developed Capture NX-D which was a disaster at first
LATER, they added U-Point and have been perfecting and supporting it ever since. It is not a bad package. AND .... it is FREE for download on their site.
OK, sorry for the delay, got busy, had to meet a deadline.
So, the first image is a SIDE BY SIDE of the ORIGINAL on the LEFT and DEFINE cleanup on the RIGHT. The image below it is PHOTOSHOPED.
Although I think the photoshop effort has a little more noise elements, if you look at the eyes and helmet, the image is sharper.
I think, if you know how to use the Noise reduction features in Photoshop, it is slightly better. Dfine is still a good package. I think I stated earlier, it just softens the image, which is something I am not crazy about.
[ so you can compare the two images, I added my editing effort next to your original image so you could see them side by side. I scaled it an tried to match color]
Black Friday is just around the corner. May be a good time to make up your mind.
I suspect a new line of Z may be coming out. Too many deals on these cameras at the moment, it seems like they are clearing the channel and making room for new announcements.
I am on the fence myself.
May spring for a Z6, I was really impressed with it, as I have stated. In Canada, the price should drop to under $1900 and I just got a promotion couple that will reduce the price another $200. Getting harder to resist.
