cliffy,
I do professional photography, weddings etc...and lots of landscapes, flowers and tons of my grandkids.
If your wife wnats to start messing around with manual settings etc this is fine, but you need to get her to start shooting pix in RAW file mode with the ADOBE RGB color space setting on the camera.
JPEGS do not have the dynamic range and are lossey. When you start playing with images in any editing program, the amount of data that is in the jpeg is not like that of a RAW file. I dont want to scare you or your wife or get real technical about the differences.
Many times in the learning process, taking photos, you will not be able to fix, or make better images in jpeg files that you can with a RAW file.
If a JPEG is properly exposed when you take it, fine, but if not the a RAW file can be a life saver.
That said, I use 2 programs for all my many thousand images:
1. Picasa 3 for general sorting and looking at images....more for just its speed and ease of finding images. Its not a color managed program, and if you print from it your prints may be not what you see on your pc screen etc. Picasa will show RAW files.
2. Photoshop CS3. Once I see an image in Picasa I like , or needs some manipulation...its into Photoshop for the corrections. Once the files are 'touched' up or adjusted I save them in TIFF format.
Not JPEG. TIFF is lossless and if you ever have to go back into the file and do something and open. close etc..there is no loss of any data.
Most cameras DSLR's come with software that will allow you to look at your images, both RAW and JPEGS etc...Your Nikon should have these utilities you might want to take a look at them as well.
If Photoshop is too costly take a look at Adobe Elements. Its very beginner friendly and can handle most of your post processing needs.
Also the manual part...I shoot hardly at all in manual!! Mostly is Aperature Priority mode, because I mostly worry and think about how an image looks and the Depth of Field is important, hence AP mode..
Ok the thing to remember is take lots of pix, have fun exploring its one of my loves for many years!
All the best
Alex
