I have never been an enthusiastic photographer, but I had to learn how when I started writing for examiner.com. Getty Images does not have appropriate photos for so many things I write! That's why I bought a Samsung SL605 camera that can load images directly to my laptop. Now, how to get the best possible picture?
If you are operating a Windows system, photos download into the Windows Live Photo Gallery. This includes a number of useful gadgets, but I've only found two of them useful - delete and resize. First delete any fuzzy or substandard images, then resize the ones you want to use on any website. Today's photos are BIG, generally around 3,000 x 4,000 pixels. A simple operation resizes them to a manageable 640 X 480 pixels. Now you can work!
Google Plus has the easiest photo editing I've ever seen. You can learn like I do - by guess and by gosh - whatever gets the picture right. I'll provide some art photos I've worked with so you can see what can be done.
For those who don't work on a shoestring budget, I would suggest getting a neutral density filter for your camera. This can allow you to better record color and objects at distances and all in all makes for a more realistic shot. For an understandable summary of these benefits, see en.wickipedia.org/wiki/Neutral_density-filter.
