Faststone is a remarkably useful photo organizing and editing program for Windows users, often referenced here, and it is FREE. (Free is good!)
It really is a wonderful program for photography; the organization it gives your files of photos alone would make it invaluable, but it is so much more. Its worst problem is the poor documentation. But once you get started it is not hard to figure out.
To Quote from CNET, taken from the Faststone site:
FastStone Image Viewer is a fast, stable, user-friendly image browser, converter and editor. It has a nice array of features that include image viewing, management, comparison, red-eye removal, emailing, resizing, cropping, retouching and color adjustments. Its innovative but intuitive full-screen mode provides quick access to EXIF information, thumbnail browser and major functionalities via hidden toolbars that pop up when your mouse touches one of the four edges of the screen. Other features include a high quality magnifier and a musical slideshow with 150+ transitional effects, as well as lossless JPEG transitions, drop shadow effects, image annotation, scanner support, histogram and much more. It supports all major graphic formats (BMP, JPEG, JPEG 2000, animated GIF, PNG, PCX, PSD, EPS, TIFF, WMF, ICO and TGA) and popular digital camera RAW formats (CRW, CR2, NEF, PEF, RAF, MRW, ORF, SRF, ARW, SR2, RW2 and DNG).
As far as I know all of this is absolutely true. Here is a very short tutorial to get you going:
First, download Faststone Image viewer at:
http://www.faststone.org/FSViewerDetail.htmLoad the program.
Press F12. This gets you to the settings menu. One the second line down, click on "Thumbnail". Now go to "Thumbnail size". Change the drop down setting to 260 X 195, then ""OK", and escape out. You may have to restart the program to get the change. At this point the program will appear to be a "Windows Explorer" optimized for photos, and in one small part of it that is exactly what it is.
Now, pick a thumbnail image and double click on it to bring it up. It should pretty well fill your screen. With your cursor anywhere in the picture, right click. And the magic begins! Explore the revealed menus. You will see that click on a lot of them will bring up sub-menus. Horizon straightening, cropping, blemish removal. Click on Editing and follow out the sub-menus. After you have tried one out, a simple <CTRL-Z> undoes it if you don't like it. a <CTRL-S> will save the changes once you confirm your desire to do so.. Check out the "colors" and the "effects" sub-menus too.
Also, to magnify a part of an image, press down the control key and use the scroll function on your mouse. Sliding the mouse around moves across the image.
Notice too the "Edit with External Program" option - which setting will when activated open the referenced program and drop the file right into it for further manipulation.
Anyhow, be sure to check it out - it is not difficult to use - all you need do is explore it so you will understand what it is capable of.
If you love photography and use a Windows computer, try it! I can't imagine you not liking it.
Cheers
