Sharpness enhancement with detail refinement gets lost during Raw development


Recommended Posts

Hi guys,

I came across the subsequent issue: I open a Raw image in affinity photo and edit the image until I am happy. However, if I then develop the Raw image, the image changes significantly. Especially the sharpness improvement I achieved with the "Detail Refinement" seems to get lost completely.

Here is an example to illustrate the problem:

 

Unedited Raw image:

Edited (only sharpened) Raw image:

After developing the Raw image:

Do I have to make any changes in the settings, so that the image looks the same, prior to and after pressing develope?

How did you create those 'raw images'? A raw image is not printable. I would guess that what you have  uploaded is actually a screenshot. This would not mean much to us unless you had it 100% on your screen.

Yes, I uploaded screenshots from what was displayed to me in affinity photo on my laptop screen.

And were they with the image at 100%? You don't need the entire image on the screen, just those parts where you need to see the detail.

Yeah, the screenshots above show the entire image.

When I said 100%, I meant 100% zoom, that is one pixel on your image corresponds to one pixel on the screen. You can zoom in by clicking Ctrl/Cmd-1. You will see that the label on the tab at the top left of the image will say 100% (amongst other things):. This is a screenshot of a raw file freshly loaded into Affinity.01RawOriginal.png.802f7714ff0ed5eec52c3a6bbfa6a0b7.png

When you upload your image, the Forum software may resize your image to ensure that it fits on the screen. This will destroy the 100% zoom and makes it difficult to compare images. I suggest that you take your screenshots with the onscreen image at 100%, then select the same rectangular area from each of you three images which show the detailed area. I would suggest cropping to about 640 by 480. These should upload without distortion. I attach below a cropped area from your first image, just to show areas which I assume you would like sharpened.

I took a closer look at that issue and compared what is displayed on my screen prior and after the raw development for different zooms. While I can identify a change during the raw development for a zoom smaller 100 %, I actually cannot see any change if I zoome to 100%. Is there any explenation for that? Is that why you wanted me to take screenshots with 100% zoom?

Yes, in the upper corner under "Develop" it should show 100% (see attachment).
What settings did you use for the detail refinement ?

Hi Dalgo :)

Viewing the document at 100% zoom will always display the pixels at their true value, when viewing the document from 'further away' (ie at a lower zoom percentage) you may find that certain effects and changes made to your image display differently than they do at 100%. 

This is because Affinity applications use mitmaps mipmaps, meaning any document previewed at less than 100% zoom will have a mitmap mipmap created and this is displayed instead, this is done for both speed/performance purposes, as well as under 100% zoom the image must be resampled to 'fit' on your screen, hence a mitmap mipmap is used. I hope this helps!

How does that differ from MIPMaps? xD
