Replacing Sky issues

[jbrent]

I am using the Afinity Photo desktop version to replace a sky in a photo that has evergreen trees.  Everything goes fine, EXCEPT, the border between the masked sky and the picture has white ghosting, looks like frost.  I have used the refining tool, but to no avail.  I am stumped.  I have attached the file for a look.  Does anyone have an idea what is causing this issue and how to fix it?  I would appreciate any help.

Hi @jbrent,

 

Welcome to the forums. 

 

You would expect this kind of result if your image is only 640x480. Refine tool mostly works on detecting edges/contrast between your selection. The more pixels you have, the better the mask will come out. On the other hand, on a 640x480, I'm really surprised it's worked this good. You can get away with it by changing the sky to a lighter tone so that it matches the "frost" around the edges. 

 

Thanks,

Gabe

Thanks for the input.  The photo you saw was reduced for upload.  The actual photo that I worked on was 4864 X 3648.  I have never seen the frosting on any of the tutorials I've watched.

Have you still got the .afphoto file? If you attach it I can have a look for you.

That looks woeful. AP is capable of much better selections. What selection tool did you use to select the sky? Can you post a screen shot of your selection settings? 

[jbrent]

I have attached the apphoto file you asked for and I have attached a screen shot of the desktop using the flood select tool.  Any suggestions????

I cannot Open this On My IPad. I notice you are using the desktop version so maybe this post needs moving.

Hopefully Gabriel can assist further.

the same on the desktop version

It's the same issue for us here.  Can you try to re-upload it or upload it to our dropbox account?

There is a very good Affinity tutorial with a alternative way to replace a sky using Blend ranges and is worth a watch, move to about 50 seconds and watch from there:

I see a lot of "replaced skies" and the biggest mistake made is the sky used to supplant the original sky isn't from the same perspective. People can view such images and know something is wrong but can't quite put their finger on why, so use a sky that is seen from the same viewpoint, elevation etc. It makes a "world" of difference.

One thing I noticed is that the Tolerance setting is only at 10%. That seems very low to me.

The blend mode tool is amazing.  Thank you firstdefence!!!

Toltec,  I am not comfortable with the tolerance setting yet.  I understand the concept but do not yet have a feel for where it needs to be set.  More practice I think.
