Painting with developer

painting with developer is when you expose your photo, and instead of putting the full thing into the developer you can get things like paint brushes and dip it into the developer and draw on you picture or you could get something like a squirt bottle and put plenty of developer in it and spray it over your picture. These techniques would give you something that look like the two pictures.Scratching negs

Scratches on the emulsion side of a black-and-white film negative will show up in the photographic prints produced from such a negative as black lines. This is because such scratches remove the emulsion from the negative.
