Turns out... It was not just me! It was indeed the camera!
My wonderful husband gave me a new camera over the weekend for our anniversary (which isn't until Saturday -- seventeen terrific years, but who's counting?)
I have been using two point and shoot cameras: a Canon PowerShot A630 and a Nikon Coolpix S220. The Canon does a pretty good job for what it is, and I suppose the same can be said for the Nikon, which was my birthday present last year. The Nikon is not much bigger than a wallet, so fits in my pocket and purse and is easily toted around to pull out to capture various moments. Unfortunately the colors are not usually true, action shots are nigh on impossible, and the right quarter of the photo is always out of focus.
I managed. I did not complain, at least not on a regular basis. (I was more than a little disappointed when the pictures from our New Orleans get-away were of such poor resolution that I could not make a photo album out of them, however.)
This new camera is a Canon digital SLR, and holy crow! does it make a difference. I had taken some pictures of the garden with the Nikon, and I scooted out and took the same pictures with the Canon later the same day.
