I am still a self-taught beginner at Photoshop, but thought I'd share what I taught myself today. I have been working on removing product names from photographs. On this one, I wanted to leave the "4" but delete the manufacturer's name and logo. Original photo:
I removed the logo successfully with a combination of Photoshop's patch tool and healing brush (working in patches), but now the 4 was much too low on the end of the weight with too much empty space above. It looked odd.
I used the lasso tool to circle the 4, created a new Layer Via Copy. I moved it into the center of the end of the weight. I then went back to my background layer (after hiding the selected 4 layer) and used the patch tool again to remove all traces of the old 4.
I did the same thing on the other weight, although that was trickier because of the extreme angle of the type. I just raised the 4 up a little bit since it wouldn't be as noticeable. After some cropping and cleanup, I ended up with this:
I don't care for the background well enough to use this as a product, but it was a fun experiment.
