See image before opacity change

So I'm trying to isolate a sprite from a screenshot of a game (I'm trying to make a drawing reference sheet from the sprites), and this sprite has an element that is translucent, so I can see part of the background behind it. Is it possible to use the background elements in some way to see what this element would have looked like without the background behind it? I've already isolated this element from the rest of the sprite onto its own layer.

Correct answer c.pfaffenbichler

i use photoshop for its drawing capabilities, it has been years since I've edited a photo with it, so I can't really remember how to do have this stuff and I can't really tell what you're doing with those pictures

can I please have a more detailed step by step?

i managed to get the mask for the wings (although I don't really understand where to apply it) and I accessed the red channel, but I don't understand what you did there


I recommend you 

• Layer > Layer Mask > From Transparency 

• cmd-G

• cmd-G

• drag the Layer Mask to the top Group 

• apply the Layer Mask of the wing area to the contained Group (and invert it, cmd-I)

• add a Solid Color Layer behind the second Group (so at the very bottom of the top Group) 

• apply the original Red-Channel as a Layer Mask to the Solid Color Layer 

• alt-click the Layer Mask and use Curves (cmd-M) to make the lightest part of the wing completely white

 

Edit: 

• Then use Clone Stamp Tool, Brush Tool or what else you prefer to remove the lines.

Difficult to imagine what are you talking about. Please post requested screenshot with Layers panel expanded and visible.

    The pictures are from a friend who has a mod of Undertale. (the bits and pieces mod)

    I have attached the screenshot from the game I got the sprite from and two screenshots of my photoshop file 

     

    Photoshop screenshot with everything

    the green background is just so I can see the white outline of the sprite, that is unrelated

    the grid is also unrelated to my issue, I have that set up for something else

    layer 3 is the rest of the sprite that isn't translucent so I don't have this issue

    Layer 5 is the wings (the part I was talking about)

    layer 2 (hidden) is my backup in case I cant fix this issue, it is pretty much layer 5 but without the gradient or background artifacts

     

    Photoshop screenshot, layer 5 and background only

    As stated, only showing the problematic layer (the more full screenshot but with layer 3 hidden, so I didn't feel the need to show the layer panel again)

     

    Game screenshot: 

    you can see the background that is showing behind the wings, I am constantly taking this in and out of photoshop to fix and change things, but it is not in this file at the moment (but could easily be brought in again)

    My friend took this screenshot (and like 100 other unrelated ones) for me to do this project

     

     

    so ideally I would like to see what the wings would have looked like if they were full opacity rather than translucent and with the background showing behind

    This is purely for my (and my friend's) personal use to draw these characters with their game sprites as references

    With Layer > Layer Mask > From Transparency I was referring to the file in a previous screenshot of yours where you had already clipped the Layer (»Layer 3«) but I noticed that you had removed the wings on that, so just use the transparency of those two Layers or recreate the Layer Mask for the whole thing anew. 

     

    »when I try to select the red channel and them do that first step, I end up with a mask on the channels tab and not the layers tab, am I doing something wrong?«

    Load the Channel as a Selection (cmd-click it in the Channels Panel), select the Layer in the Layers Panel and apply the Layer Mask via the button or Layer > Layer Mask > From Transparency


    Sorry I took so long to try,  but I've now tried 

    (Once again, green layer is just for more contrast between the background and the sprite, hidden in both screenshots)

    I've named the groups by what the mask on them is so I don't get confused (again)

     

    So, I manually made a mask of the whole sprite just so I didn't have to deal with the background (I copied layer 1 and manually removed the background and made that layer into a mask and applied it on that group, probably not the most efficient way to do it but that's how I've been doing it and it works so I'm not changing)

    the body bit (group "all but wings" and the contained layer) hasn't changed I don't think since last time

    Your instructions helped me to select the stuff for the layer based on the red channel, but the gradient on the wings didn't seem to work? (Second image is hiding the "all but wings" group so you can see the mask. There is different opacities throughout the image but the wings all seem the same)

     

    I don't understand what you meant by "• alt-click the Layer Mask and use Curves (cmd-M) to make the lightest part of the wing completely white"
