"Picky Details" for the Kodak EasyShare C360 digital camera
(Timing, Power, and Storage Info)
Timing
When you press the shutter release on a camera, there's usually a lag time or delay before the shutter actually fires. This corresponds to the time required for the autofocus and autoexposure mechanisms time to do their work, and can amount to a fairly long delay in some situations. Since this number is rarely reported on (and even more rarely reported accurately), and can significantly affect the picture taking experience, I routinely measure both shutter delay and shot to shot cycle times for all cameras I test, using a test system I designed and built for the purpose. (Crystal-controlled, with a resolution of 0.001 second.) Here are the numbers I collected for the Kodak EasyShare C360:
|
||
|
(secs) |
|
Power On -> First shot |
|
LCD turns on and lens extends forward.
|
Shutdown |
|
First time is time to retract lens, second time is
worst-case buffer-clearing time.
|
Play to Record, first shot |
|
Time until first shot is captured.
|
Record to play |
|
First time is that required to display a large/fine
file immediately after capture, second time is that needed to display
a large/fine file that has already been processed and stored on the
memory card.
|
Shutter lag, full autofocus |
|
First time is at full wide-angle, second is full telephoto. |
Shutter lag, continuous autofocus |
|
Continuous autofocus helps a little with stationary subjects (unusual, on most cameras it doesn't), may help more with moving ones, but we have no way to reliably test AF performance with moving subjects.
|
Shutter lag, prefocus |
0.112
|
Time to capture, after half-pressing shutter button. |
Cycle Time, max/min resolution |
2.34 / |
First number is for highest resolution files, second number is time for smallest files. Times are averages. In highest-res mode, shoots 6 frames this fast, then slows to about 6.3 seconds per shot. Times are averages. In lowest-res mode, shoots 5 frames this fast, then slows to about 5.8 seconds per shot. Buffer clears in 33 seconds in high-res mode, 30 seconds in low-res mode. |
Cycle Time, Flash exposures | 4.5 |
Flash at maximum power output. Camera allows picture to be taken before flash recharges! |
Cycle Time, continuous mode, max/min resolution | 0.50 (2.0 fps) |
First number is for highest resolution files, second number is time for smallest files. Times are averages. Shoots a burst of 5 frames this fast regardless of resolution. Buffer clears in 39 seconds in high-res mode, 36 seconds in low-res mode. |
Power
The Kodak EasyShare C360 uses a two AA batteries or one CRV3 for power, and a CRV3 battery is included with the camera. The table below shows the power drain I measured in various operating modes, and the corresponding run times to be expected from a standard set of 1600 mAh NiMH cells.

Storage Capacity
The Kodak EasyShare C360 stores its photos on SD / MMC memory cards or in approximately 29 MB of internal memory, and no card is included with the camera. (I strongly recommend buying at least a 64 MB card, preferably a 128 MB one, to give yourself extra space for extended outings.) The chart below shows how many images can be stored in the internal memory at each size/quality setting.

Download Speed
The Kodak EasyShare C360 connects to a host computer via a USB interface. Downloading files to my Sony desktop running Windows XP (Pentium IV, 2.4 GHz), I clocked it at 769 KBytes/second. (Cameras with slow USB interfaces run as low as 300 KB/s, cameras with fast v1.1 interfaces run as high as 600 KB/s. Cameras with USB v2.0 interfaces run as fast as several megabytes/second.)
