If you have Adobe CS5 you can do it much quicker with the “content aware fill.” Just type that into youtube for a tutorial.
The only tip I would add is the use of the “Healing Brush Tool.” It’s the second little band-aid looking one. Do all the rough fill with the clone tool or content aware fill, and then anything that didn’t blend well, go over with the healing brush. It should make it pretty seamless.
Removing objects is not always possible depending on the complexity of the background and surrounding area. Sky, dense foliage, and water are simple. In the Pisa photo I cloned some of the elements on the horizon. I copied a few trees and extended the slope of the mountain. And I just carried the line of the buildings over a bit. Trial and error is key. And the undo option is your friend. I set my undo states to 1000. Each picture is different and will present new challenges. But with practice you can remove objects pretty seamlessly without a fuss.
The well has dried up. I did a thing with a fish yesterday and that’s all I had going for me. I was going to do a cereal box photoshop. It was going to be “Rebecca Black’s Friday Flakes.” But it would be like a 4 hour job and I feel like people are getting sick of her. I think I need a muse. Something to inspire me. Right now any creative energy I have goes to my job. Then I sulk for a while. Then I check tumblr. Sulk more. Eat various foodstuffs. Sulk. Watch old episodes of The Office. Sulk. Sulk. Tumblr. And of course there is napping throughout the day.
How long are you supposed to feel like crap after a breakup?
