Hewlett Packard PhotoSmart 812 Review
Timings & File Sizes
The 812 did feel slow by modern day standards. Power on was in line with what we'd expect of an 'extending lens' compact. However almost every other function took longer than we would expect. Most noticeable was the camera's autofocus which almost always took longer than 1.5 seconds. On top of that the 812 also had a consistent 0.2 second shutter release lag, which again is slower than most modern cameras.
Timing Notes: All times calculated as an average of three operations. Unless otherwise stated all timings were made on a 2272 x 1712 JPEG image (approx. 1.1 MB per image). The media used for these tests was a 128 MB SanDisk SD card.
Power: Off to On
|Power: On to Off||Lens extended||4.2|
|Mode: Play image||Image displayed||1.2|
|Play: Magnify||4x magnification||5.3|
|Zoom from Wide to Tele||Full zoom from 37 mm to 111 mm (3 x)||1.5|
|Auto Focus LAG||Wide angle (37 mm) *1||1.5 - 2.2|
|Auto Focus LAG||Telephoto (102 mm) *1||1.7 - 2.2|
|Shutter Release LAG||Using viewfinder||0.2|
|Shutter Release LAG||Using LCD monitor||0.2|
|Off to Shot Taken||5.5|
|Shot to Shot||Zoom at wide angle, record review set to 1 second||4.5|
|Shot to Shot||Zoom at wide angle, record review disabled||4.5|
|*1||AF was slightly quicker (about 0.2 secs) with the LCD monitor turned off.|
|*2||Interestingly a full depress of the shutter release and the camera responded quicker than the amount of time it took for a half-press (of the same scene) to come back with a confirmed AF lock. That is, if you just half-press it took approximately 1.7 seconds to come back with the green [ ] brackets. However if you simply fully depress the entire sequence (exposure, AF, shot taken) took around 1.5 seconds|
Auto Focus LAG is (roughly) the amount of time it takes the camera to autofocus (a half-press and hold of the shutter release button), this timing is normally the most variable as its affected by the subject matter, current focus position, still or moving subject etc. This timing is an average.
Shutter Release LAG is the amount of time it takes to take the shot after autofocus, this timing assumes you have already focused (half-pressed the shutter release) and now press the shutter release button all the way down to take the shot. This timing is an average.
Total LAG is the total time it takes (not just the two above added together) if you haven't pre-focused, that is no finger touching the shutter release button, press it all the way down in one movement, this new timing is how long it'd take if you were in one of those spur-of-the-moment situations. This timing is an average.
File Write / Display and Sizes
Timings shown below are the time taken for the camera to process and "flush" the image out to the SD card, the timer was started as soon as the shutter release was pressed (shutter click was heard) and stopped when activity indicator LED beside the SD compartment returned to green colour. This means the timings also include the cameras processing time and as such are more representative of the actual time to "complete the task". The media used for these tests was a 128 MB SanDisk SD card.
|No. on supplied 16 MB CF Card|
|2272 x 1712||26.4||9.5||2,300 KB||7|
|2272 x 1712||19.9||5.2||1,100 KB||15|
|1136 x 856||17.4||2.8||500 KB||30|
|1136 x 856||15.9||2.0||250 KB||60|
|*1||Image playback is almost immediate, the only way to test 'load time' is to magnify the image. Selecting magnify forces the camera to load the full resolution image from the SD card.|
|*2||All file sizes are an average of three files. As is the case with JPEG it's difficult to predict the size of an image because it will vary a fair amount depending on the content of the image (especially the amount of detail captured). For example, take a photograph of a fairly empty wall and you'll get a small JPEG, take a photograph of a bush with a lot of detail and you'll get a larger image. File sizes here are closer to the later, the larger size of file you should expect.|
The above write times are some of the slowest I've seen on any digital camera. It takes a whole twenty six seconds to write a 2.3 MB file, that's an incredibly slow 90 KB/sec. Luckily the 812 does have a fairly large buffer which allows you to shoot up to 5 x quality images in a row without having to wait for the camera. As soon as the buffer fills the camera will display 'PROCESSING...'.
We ran the camera through our new battery life test. This test is designed to be fair and comparative to each camera and battery type:
- Take 4 shots without flash
- Wait 2 minutes (50% of the time powering the camera off)
- Take 1 shot with flash
- Wait 1 minute
Batteries are fully discharged and recharged before the test and all cameras were reset to their factory default settings. Here are the results:

|Other test notes:|
| LCD monitor is left on during
the battery test
The camera is powered off half of the time and left on half of the time (switch every 10 iterations)
There are now higher capacity AA NiMH batteries available, however in the interests of fair
comparison we will continue to use our 1600 mAh test set
Here's somewhere the 812 did really well. On just two AA batteries the camera lasted well over two hours in our test. This is probably down to the fact that the camera turns off the LCD monitor after one minute of inactivity (and there aren't any other power save options).
