Unfortunately, the less I use it, the worse I get. So snagging my "nice" camera for a vacation, then spending a lot of time making sure I lug it around and use it, and then having the results be, frankly, bad, is really frustrating. In particular, I have quite a few photos that are.. either blurry, or out of focus, and it's hard to tell which. I am pretty careful to ensure I hold the camera still, and have a sufficient shutter speed, but I'm definitely messing something up.
I need to take more time to practice at home rather than capturing a thousand frames over 3 weeks and hoping they're good (like the bad old days of film!)
