Use "Apply Image" to create a mask for blending multiple images?

Recommended Posts

Hello,

 

I have a question regarding the "Apply Image" function. I saw a tutorial where Apply Image was used in Photoshop to change the mask of an image to become the source image but as a mask (so just the dark and bright information). It was used to blend multiple exposures together. 

 

Is it also possible with the Apply Image feature in AP, or is there any other option?

 

I hope it is clear what I mean, because I find it hard to explain.

 

Thanks in advance :)

I'm not sure.. but if you go Layer>rasterise to mask, is this what you what you want?

Hmm I mean if you have for example 3 different exposures from a bracketing and you just want to use the sky from the darker exposure I want to create a mask, where just the brighter things in the image(in this case the sky) is visible, so just the darker sky will be visible on top of the brighter exposures.
 
Like this guy does it in this video at 05:13 for example:

If I understand your aim correctly, you can accomplish what you're after using Blend Options, Luminosity Masking, or you could do this (which - I think - more closely approximates the flow you're after):

 

1) Open 2 versions of the picture (exposure bracketed). I've done this with two photos which I'll call "darker" and "lighter"

2) Copy the darker picture on top of the lighter picture. Now you have 2 layers.

 

3) Duplicate the darker layer and add a Black and White adjustment.

4) Select the Black and White layer. From the Layer menu, choose "Rasterize to Mask"

 

5) Drag the mask that results from this into the "darker" layer.

I have a question, if i want the more grungy sky from a darker image be my sky in my ligher image, how can i achieve it? In photoshop i used to use apply image and then use it as a multiplied mask so only the shadows from the sky show. but i can't make a mask from an applied image in affinity. I tried using luminosity masking but that didn't work
