CSM 5: FILE NUMBER SEQUENCE
This is actually important. You want sequencing of your photos and folders because you could accidentally replace a previous folder of photos on your desktop. As a side note, the Minolta S404 did not have this feature, and I actually did replace about 10 photos unintentionally. So, the moment you get your D100 or if you haven't done this yet, do it now. I assumed this feature was defaulted to "ON". Well, it's not.
CSM 6: MONITOR OFF DELAY
You can adjust how long you want to view a photo when you press the Monitor Button, from 10sec - 10min. Of course, the more time you spend
using the monitor to display your photos, the more battery juice you are sacrficing. I have mine set to 20sec, which is the default setting, and it is quite sufficient. If you feel you need more time to view your photos, the next setting is 1min. I was hoping there would be a 30sec setting, because
20s - 1min is a big variance. Minor peeve.
CSM 7: AUTO CAMERA METERING
When your D100 is in "standby" mode (i.e., when it temporarily shuts down due to lact of use), you have the option
of telling the D100, just how long should the camera meter after it shuts down. You can set the auto exposure metering anywhere from 4 seconds to 30 minutes.
CSM 8: SELF-TIMER
Pretty simple. Anywhere from 2-seconds to 20-seconds can be selected so you can put yourself in a portrait with friends, etc.
CSM 9: EV STEP (1/2 or 1/3?)
The finer the increments in EV, the better--it gives you more precise control over how your photos will turn out. This was one of the reasons I chose the D100. I would leave this at the default, unless you need to do otherwise.
Important Note: In order to take advantage of the D100's highest flash sync rating, which is 1/180th of a second, you have to switch
the EV to 1/2 step. The default of 1/3 EV, will not be appropriate.
CSM 10: EXPOSURE COMP
Basically, just a preference of what buttons will do what (Page 152).
CSM 11: BKT SET
Ok, this is where things get a little complicated. Braketing is certainly a nice little tool that enables
you to get the best exposure, flash level, and White Balance of your photo, when in situations where you just can't seem to find the right combination. I wish I would have used this feature earlier for some hockey pics, but, like most who are reading this, I am learning. I would certainly take some time to learn this CSM setting. It works with your bracketing (Page 153).And I can't state this enough: Use Bracketing in cases where you just can't get the desired light balance of your photos. Have a yellowish or greenish color on your photos? Bracket (or find someone who is witty with Photoshop!).
