# Usage

First of all you will have to configure your camera to use the USB mass storage interface (not the PTP one) in the case your camera has this option. Consult your user's manual to do that. Also, it would be convenient to uninstall Nikon View.

## Connection settings

Turn on the camera, turn the dial to A or M mode, select the preferred exposure mode (P, S, A or M) and set the aperture/speed if required. If you are using a serial or dual cable and want krinnicam to control the shutter speed (reliable only for speeds slower than 1/30), then you should set Bulb exposures on the camera.

Plug the camera to the computer; if you are using the USB cable, wait for some seconds until the camera is recognized. Then start krinnicam, select your camera model (krinnicam will remember this setting for future sessions), and click on the "Connect" button.

## Camera settings

After a while, krinnicam will show the current camera settings. With it, you can turn the LCD monitor on/off, zoom in/out (currently only works with some camera models), change some settings such as focus mode, etc.

If you are using a serial or dual cable, you can also change settings directly on the camera if you enter in the MC-EU1 emulation mode, by clicking in the Turn LCD On button. In this mode, camera buttons are responsive. Otherwise, you should disconnect, unplug the cable, change camera settings, plug again the cable, and connect again.

## Intervalometer function

Of course you can use krinnicam to shoot a series of any number of images ("Repeat" box), defining the time interval between them ("Interval") and the delay for the first picture ("Initial"). Note that you can set any value for these fields, you are not restricted to the values listed in the pulldown lists. If you want, you can instruct krinnicam to download the shots to the computer.

If you're using a serial or dual cable and set your camera to bulb mode, you can also specify the shutter speed setting. Otherwise, krinnicam shutter setting is ignored and camera settings will be used. If you want speeds higher than 1/30 seconds, this is the only way to go.

## Download settings

There are three possible behaviours for this feature:

• Off: don't download anything;
• After each: download each picture inmediately after it is shot;
• After last: download all the pictures shot when all shooting is done.

After each has the advantage of having a virtually unlimited number of shots, because krinnicam will move picture files from the camera to the computer as they are shot, so the memory card will never be full; on the other hand, as downloading files from the camera takes some time, 'interval' setting should be high enough to account for it; otherwise, krinnicam will not meet the value you specify and will try to shoot and download as fast as it can.

If activated, downloaded files will be moved to the directory specified in these settings.

krinnicam will rename the picture files that it downloads. You can specify a (somewhat) basic rule for this task. There are three predefined rules:

• KCAMnnnn.ext: will produce sequential filenames like KCAM0001.JPG, KCAM0002.JPG, etc.;
• yyyy-mm-dd_hh-mm-ss.ext: will produce filenames based on EXIF date and time data, like 2006-08-23_18-46-02.JPG;
• yyyy-mm-ddKCAMnnnn.ext: will create sequential filenames, like the first rule, but organized in folders, one for each day (based on EXIF date, like the second rule).

You can specify your own rule by selecting <Folder><Filename>.ext option, and providing your own patterns for files and folder names, e.g., if pattern is SEQ%s and patern is seq_%d_%t, krinnicam will create a new folder for each session, SEQ0001, SEQ0002, etc. and the files will be named like seq_2006-08-23_19-01-01.jpg (again, based on EXIF date and time data). You should care for name clashes, e.g., if pattern is %t and two pictures have been shot in different dates but equal times, the second (and following) will not be transferred, but be kept at the camera memory card.
