Adobe 'Preserve Details 2.0'

I thought I would share this as I mentioned it on another thread a few days ago - https://www.dpreview.com/forums/post/63120029

I have mainly tried this with the Merrils, however, the below is with the DP3Q.

The first two are a comparison between SPP 'SHI' enlargement setting and adobe's Preserve Details 2.0.

Sharpening -2

Detail setting - (1/7)

Chroma and Lum Noise - 2/5

Please tell me if the above would present an issue? I merely wanted to get rid of any sharpening that SPP was doing as I dont think it's that good at it. Although the Detail setting might be better / ok to us.

Preserve Details 2.0 to the same res at SHI

SPP SHI Setting

The difference below is far more noticable.

Preserve Details 2.0 - Double Size

SPP Double Size

Someone might know if the settings I have used are just all wrong? I am just trying it again with Double size with -1 sharpening and detail set to 3/7.

Re: Adobe 'Preserve Details 2.0'

One more example.

Detail 3 out of 7

Sharpening to -1

Clarity and fine detail is vastly better with Photoshops 'preserve 2.0' but the one small negative is the noise. It is more noticeable with preserve details 2.0 but I am assuming that it is because the 'Double size' setting on SPP doesn't produce critically sharp image so it disguises the noise. Saying that though, the noise is still only noticeable when viewing the image at 200-300%. At 100% you cannot tell, plus at that point we have already increased the pixel count by 4 times.

One last thing to note  - File size of preserve 2.0 is about 30-50% larger than double size from SPP.

Yeah, PhotoZoom Pro works better than SPP at up-scaling the photos too, so it makes more sense to just create jpegs or TIFFs at normal size, and then scale them up using some other program. Sigma should improve their scaling feature in SPP, right?

I also did some interpolation with photoshop (keep details 2.0) of photos from Quattro, visible on this link:

https://www.dpreview.com/forums/thread/4304645

I set the sharpness to -2. The details, I leave in the middle. And NR luminance at 0, completely left.

But the results obtained with Gigapixel AI, are much better.

Here is your photo interpolated to 78.5 MP (double) with Gigapixel AI.

Even with the GFX 50R a interpolated photos to the same definition, I'm not sure the result is as good.

There is a strange object on the left of the tree behind the house with the 2 large chimneys.
Probably a bird.

Re: Adobe 'Preserve Details 2.0'

Superb detail in the Quattro image and Gigapixel is an amazing programme for sure and gets every bit out of it. I purchased it last week.

Gigapixel always seems a bit better than the preserve details 2.0 on all images that I have tried. Shame its slow.

I did some tests with photos from the GFX 50R https://www.photographyblog.com/reviews/fujifilm_gfx_50r_review , the result at 78.5MP is worse than the Quattro. the rendering of fine details, textures is less good. With the quattro the result gives a better feeling of relief of realism.
The rendering with the GFX looks a bit plastic.

It would be interesting to compare on one or more photos of the same subject.

Re: Adobe 'Preserve Details 2.0'

From my point of view, it is better to use the quattro in UHT definition, to fully exploit the potential of the sensor.

Re: Adobe 'Preserve Details 2.0'

I own both the GFX 50r and 110mm F2 lens so I can post a few comparisons for you. I'll give you the RAW files on here. That lens is stellar so if the DP3 Q hold up its quite a feat.
