Is there any software available on the net where you can check whether the horizon level of your photograph is alright or not? And also please let me know that how can I change the background of a photograph, I mean which software to be used? Does picasa has that feature? It may sound strange but believe me I am not a big fan of post processing so don't know much about it.

| Bhas, just about any photo editing program will have the option to rotate images by degrees. You can also get a hotshoe bubble level for your camera to make sure your shots are level.

Bhas, the easiest way that I've found (PS Elements) is to eyeball it, do a rotate approximation, bring out crop tool and compare to rotation, then make rotation adjustments as needed.
Go when you can, go where you can, shoot what you can

| Actually if you have PS or PS Elements, you should have a lens correction tool. Simply click on one end of the horizon and click on the other end of the horizon and PS will use those two points to create a perfectly level horizon.

When you rotate an image, any postprocessing application will need to resample the image and interpolate the pixels. Image quality will be lost with rotation!!!!!! If you want to know more, please read Digital Image Interpolation. It's important!
Will said it very well. Invest $50 in a double bubble level indicator, which you can attach to your hot shoe. Get the horizon square from the word "go", so you don't have to rotate the image with resolution destructive software.

I found that putting the grid lines up on the wee screen on my camera really helped me keep the horizon level so that i don't have to fix it when i get them onto my computer. I have a point and shoot....so this is an easy thing to do.
Do digi slrs have grid lines in the viewfinder???
