No problem! First off,
EXchangeable Image Format or EXIF is a term used with digital photography to describe the settings used when you take a the picture. An example might be something like this:
EXIF: Nikon D300, Nikkor 35mm f/1.8G, handheld, ISO 800, 1/15, f/1.8, -2/3 EV
There are a couple ways to get this information. On a PC or a Mac, you can right click on the image and get some of it
depending on whether you post processed and how you saved it. I downloaded and saved your file on my Mac, right clicked and got this:
Nikon D60, unknown lens at 36mm, unknown ISO, 1/2, f/5.3
I then opened the file with Photoshop and got the rest:
Nikon D60, 18-55mm lens @ 36mm, ISO 640, 1/2, f/5.3, white balance set to Tungsten, Manual exposure
If you don't have Photoshop, you probably have ViewNX which came with your camera. You can also get this info there.
So now you're probably wondering why I asked for this, right? I'm sure other more technical folks will also comment, but a couple things jump out at me. One reason the letters might be a little yellow, is the white balance. Did you have it set at auto?
Also, since aperture controls depth of field and that you used manual exposure mode, it gives me a clue as to how you wanted to capture the image.
Hopefully you won't mind, but since I had the image in Photoshop I took a quick pass at cropping and a curve adjustment. What do you think?
