Warning: Newbie ahead…

Given two images: a background image and an image with a logo in a corner.

Having superimposed the logo over the image with 50% opacity, I have then flattened the image and saved it.

Question: How do I get back the original image?

(I do have it, it’s just that this seems a good example to learn the most basic image editing.)

I (think I ) know how to do this in theory (correct me if I’m wrong): – make a mask using the logo image (done that with threshold) – invert mask so changes are only applied to the logo area (done) – save this mask as alpha channel (done)
Now what?
– create a layer with inverted logo image (to cancel out the logo) ??? – apply this logo layer to flattened image through the mask (stumped?)

How do I do this? Baby steps, please!

Thanks!

Don.

You can’t. If it’s not too complicated cloning with the Rubber Stamp is about all you can do.

Hint: Use Image->Apply Image. You will need to do some simple algebra to figure out the correct settings. I could show you how to do it if I were awake, but I’m sleep typing. Write down the formula that adobe uses to flatten layers when one is at 50% opacity. Solve the formula for thr original image in terms of the flattened image and the logo. Then figure how to apply that formula with photod-shops limited prowess in arithmetic.

Probably several other ways to do it, too, like with layers. or channel operations. Use whatever you’re comfortable with.

Reading between the lines…

Now why would you want to take someone’s logo off their art?

Reading the lines themselves, there’s one slight problem in the "logic" of your conspiracy theory:

How did I get the original (clean) logo image, then?

I don’t know that you have a "clean logo image"… all you have told me that you want to do is take the logo out of an image…make the image clean, with no logo in the image.

If you were the real artist of the image you would have a clean image and have no need to take out the logo to begin with.

Never heard of an artist that did not save versions of his work as he was going along.

Ah, yes… The plot thickens! Or should that be "the thick plotten"?

If you bothered to read the original message you would have read:

If you were the real artist of the image you would have a clean image and have no need to take out the logo to begin with.

Again, reading the original message you so conveniently ignored:

(I do have it, it’s just that this seems a good example to learn the most basic image editing.)

Never heard of an artist that did not save versions of his work as he was going along.

And so you jump to irrational "conclusions" and cast insulting aspersions…

But with your demonstrated propensity for not reading before replying, I doubt very much you got this far, so I don’t expect an apology.
