The detail on the native image is excellent. The Topaz upscale looks fine when seen at website resolution (= downscaled) but is very unnatural when looked at full size.Nuthatch

Thank you, Click!I really like the "vignetting effect" created by the foliage surrounding the subject. Very nice composition.
That's superb. I find Topaz AI works well with soft images but oversharpens ones that are already sharp. I use Topaz Gigapixel for those as I seem to have more control. I posted a Nuthatch just a week ago. It was at iso 10k not as sharp as yours. Here is a crop of its head and the AI upscale. The enhance function gives a more natural response. This is why I wrote elsewhere that Topaz is a great leveller of lenses - the RF 100-400 catches up a bit to the 100-500mm with it!The nativ crop of 1908x1073px:

I use Gigapixel for upscaling low resolution images. It can give good results.Could you please explain when you use gigapixel?
I thought it was mostly for prints.
PS: I'm "afraid" your answer will make me buy Gigapixel after you already convinced me to bus "Sharpen" and "Denoise".![]()
The middle one is oversharpened. I usually turn off lens sharpening in DxO before using Topaz.Thank you!
I will give Gigapixel a try! I bought the black friday bundle including Gigapixel but haven't installed it yet.
Your examples show the power of the software and are good reasons the try it.
Here is another longtailed tit shot with R5 and Rf 100-500 + 1.4TC only denoised by Topaz.

Just WOW!Perfect, absolutely perfect!
(Once again!)
Here's something from this afternoon. I had the R7 and RF 100-400mm, and took a shot of a large flock of Lapwings whirling around. I could take a crop of a group, each of which occupied a few pixels, and Topaz AI enhance upscaled it 3.4x and filled in some detail and sharpened it. Here is the full image dowscaled, the crop at 100% and the Topaz enhanced. The Topaz will print larger and looks sharper on screen.Could you please explain when you use gigapixel?

Thanks for your answer. The result is quite convincing, I'll place an order.Here's something from this afternoon.

Just for you then! The murmuration of Lapwings today, and a crop and Topaz Enhance 4x enlarged crop, which are good enough to identify that they are Lapwings. Each bird is only about 20px x 30px. Says something good about the sharpness of the RF 100-400mm on the R7.Thanks for your answer. The result is quite convincing, I'll place an order.
PS: it's 30 years since I saw so many lapwings where I live in Alsace. Now, if I'm lucky, it's one or two birds in a whole summer... Sad.



Looks like all our French lapwings were abducted by the "la perfide Albion"Just for you then!
