when putting text on a photo
for a quick and dirty improvement in readability/prettiness, you should put a small shadow around it to make the text edges look crisper. How I do this in Photoshop:
- duplicate the text layer
- make the text in the new layer black (for black text, I make the shadow one of the colors from the background)
- rasterize the new text layer and move it behind the original text layer
- do filter > blur > guassian blur. a 1-3 pixel blur should be plenty to make the letter edges sharper.
- sometimes I reduce the opacity of the shadow layer.
the second image has a black shadow on the white text and a pinkish shadow on the black text.
