I used to use picnik online, until Google bought it and absorbed it. Of course, this was a very basic and low-grade program; however, it did have lots of filters and effects, that I found fun to mess around with. Since then, I've used nothing. No post processing; just raw images.
I've always used point and shoot digital cameras, and held the concept that mastering a rudimentary tool is far more admirable than skimming the surface with an advanced tool. The fact that I could never afford a professional camera may have biased me in that direction, alongside seeing friends get into photography as a hobby, buy thousands of dollars worth of state-of-the-art equipment, only to use it twice a month. So I have a great respect for getting a beautiful, crisp capture with a less-likely device, and I think I've done just that, on occasion!
I actually don't even have a proper camera anymore; the advent of cell phone cameras, and my acquisition of an iPhone as well as an app called Camera+, totally took over. But I DO still have over 9,000 images from years passed to go through- including some that I've posted- to play with.
This is my goal: take good images and make them great; bring out the potential in my pictures and make them awe-inspiring. Begin the transition from amateur to professional.
So I'm dipping my toes into photo editing, starting with Pixlr online (beginner friendly, but slow), Adobe Photoshop's Lightroom, and eventually Photoshop. I've used photoshop a little, but only for very basic and very specific functions. So I'm pretty much starting from ground zero. I've watched a few tutorials on YouTube (thanks so far to LightroomZen!) and remember as I write this that deviants here create wonderful tutorials as well.
Please share any great tutorials you come across, on here and from around the web. All your input is loved and appreciated.
