Really good scanner and paper feed
2008-06-21The immediate "send to printer" function doesn't seem to work, but this really scans well, and has easy to use software. Good paper feeder
One headache after another
2008-02-26My employer here in San Francisco (I'm not in Kentucky like is says above) purchased one of these scanners to help us go paperless in the office. We have tons of paper documents that need to be scanned and archived. However, using this scanner has been one headache after another. Yes, it is fast, but it also jams often, and often grabs more than one page at at time(if this doesn't cause it to jam then it simply means pages end up missing in the scan). The worst part is that after a jamming episode it simply won't interface with Adobe Acrobat again unless it is shut down and rebooted. This happens A LOT. Sometimes it stops interfacing even without jamming. It's not unusual to have to reboot the scanner several times an hour. I'm not sure if it's a hardware or software issue, all I know is that it has been a pain in the neck for months. And of course, HP customer service is notoriously bad so that only makes a bad situation worse. We've barely had this scanner 6 months and have already decided to replace it. We recently ordered a Fujitsu FI-5120C and I have high hopes, based on its reviews, that my scanning headaches are over. As for this HP, what an expensive mistake it was. Also, btw, it makes a very annoying high pitched sound while scanning that made scanning very unpleasant.

The types of camcorders
If you are planning on purchasing a camcorder, you should be familiar with
the types of camcorders and how they can benefit your specific needs. The
formats of video cameras include, VHS, VHS-C,
8mm, Hi8, Mini Digital Video (Mini DV), DVD and Digital 8. Each format has
its pros and cons
VHS
The VHS format is the oldest type of camcorder. This type of video camcorder
is fast becoming outdated, because you can only play back
the video on a VHS VCR system. VHS
camcorders are not nearly as clear as digital
video camcorders that offer clear video with 540 lines of resolution,
VHS video cameras only offer 240 lines of resolution. They also weigh more
and are much more bulky, that dv camcorders. You can only find these video
camera used because their technology is now outdated.
VHS-C
The VHS-C format offer 240 lines of resolution, just like VHS. These analog
camcorders come in a smaller size that the VHS camcorder models, but use
the same technology. The video tapes u ...
Camera basics: shutter-speed, aperture and ISO
In this article, I’ll introduce you to the basic elements that you can use to control exposure in your shooting. If you have a digital SLR, there will be a way to set all of these controls on your camera, but since they differ between manufacturers and models, you’ll need to refer to your camera’s manual to find out exactly how to change them.
All cameras, whether an ancient film camera, or a more modern digital, work in pretty much the same way. Photographs are taken by letting light fall onto a light-sensitive medium, which records the image. Traditionally, this has been film, but more recently, it tends to be a digital sensor. The more light that falls onto the film or sensor, the lighter the image.
Put simply, a camera consists of a light-tight box that stores a light-sensitive device (either a film or a digital sensor), a lens that magnifies and focuses the image onto that light-sensitive device through a hole in the box (called the aperture) , and a shutter that opens ...
