actually if you want to make a photo look sweet ass bitchin' hawt, then there is a trick i was taught. if an image looks grainy you can blur. but then it looks blurry right? "duh" after you blur the image, duplicate the layer. then, do a 'filter/other/high pass' and set the radius to about 10. then just set that later to soft light. that will find the highlights in the image and make them more crisp. it works well for photo correction. (that is what i do, well, try to do)
sharpen then blur,
use once and destroy,
make it all feel worthless
while it isn't.
just another means of coding and decoding art.
...dunno, it's late . please excuse possible meaningless ramblings. but you asked .
Voted sharpen because there was no "solarise" category.
Also because there was no "sharpen and blur" category -- to sharpen then blur implies a sequence, once must first sharpen before blurring. What if you sharpened and decided you only wanted to blur some things, not everything? This is often how people live -- seeing some things, deluding themselves into not seeing others.
sharpen then blur. i find sharpening an image once its been blurred makes little noisy dots if u do it a few times. sharpening first keeps the sharpness and blurring takes the edge off it and gives a better atmosphere
