hmm, actually it’s really simple. first, create a brightness/contrast adjustment layer. set brightness to 150, contrast to 46. then create a hue/saturation adjustment layer on top of it. set the saturation to 51. but sometimes, tumblr is being an uploading bitch that errors ‘cause the colors seem to bright, you might need to decrease it into 45. and that’s it! if you’re not satisfied with the results.. you might want to adjust them a bit and add a color balance adjustment layer. that’s pretty much it. i can’t promise it works on everything. but, i really do hope this helps. :)
