Nikon D200 User Manual
Page 44
PTP is used if you want to control your D200 as an external device, e.g. via Nikon Capture
for remote camera control. PTP makes the D200 look like a device instead of like a drive.
Dust Off Ref Photo
if you pay Nikon another $100 for Nikon Capture software you can
use this to erase the dust more easily from your raw images. I don't do this!
I've made 24,000 shots on my D200 and have no problems with dust. Thankfully the D200
sensor has a filter far enough from the imaging surface to throw dust out of focus.
Battery Info
I use all the time.
Bat. Meter reads the battery charge to the nearest one percent. This is the same data
shown on the top LCD display, but the top gauge has 5 bars & reads to the nearest 20%.
Pic. Meter shows how many images have been shot on this charge.
Charg. Life shows the battery's health. A new one reads 0 and a near dead one reads 4.
I've made 24,000 shots by alternating between two batteries, and they both still show
"new." The trick is not to run them all the way down before charging.
Firmware Version
lets you confirm if your camera is up-to-date with Nikons' free
firmware updates. Mine reads A 1.01 and B 1.00.
