I've been taking closeups of snowflakes using my SD1100 and a magnetic macro lens. I have gotten some pretty decent results handheld, but obviously the biggest challenge for such tiny closeup work is getting the snowflake in perfect focus. I am trying to implement focus peaking to help.
So, I turned on the chdk, and went into the menu and tried to turn on Edge Overlay. I tried this twice, and both times, as soon as I turned it on, the camera froze completely. I had to take out the battery to get it to start up again, and even after turning it off and back on, the screen was all messed up - its hard to describe, it was strobing and I could see a faint impression of the chdk menus. It did this even as I turned it off and on a couple times. I then let it sit off for awhile and turned it back on again and it seems ok, so I don't think there was any lasting damage.
But, since this happened the same way both times I tried to turn on edge overlay, it seems like I won't be able to use focus peaking. Any advice? Thanks!
