I have a copy of Elements8 which came with my printer, but I'm still learning all of it's functions. A copy of Lightroom is on my (sadly ever growing) wish list. I currently edit my photos with GIMP and Picnik.
I absolutely love playing and editing a photographs; adding texture, layer masks, words, playing with curves (oooh la la), sharpening and softening. It all gets me downright giddy.
In order for me to process pictures for clients in a reasonable time frame I tend to do a quick run through and delete all those I am immediately unsatisfied with and then group the remaining images into locations or scenes. From there I'll time through each group and pick my favourites. I am also very picky but for me this means I will work and re-work a photo for hours upon hours. I am still learning when it's time to walk away from a photograph that can't be 'fixed'.
