Nice Camera
I looked at many brands including Sony and Canon. I liked the idea of having the docking station that I just plug the camera into and can view easily on my TV. It also uploads the pictures very easily and the software that comes with it works great. I can easily have it email the pictures automaticaly or have them displayed on a web page automaticaly. I can’t wait to get my new HP printer to print off some pics.

I had actually bought a Sony camera for the same price and returned it to buy this one. The Sony was only 3.1mp and had only 2x optical and 3 way digital zoom. This has 3X optical and 7X digital zoom. The other big advantage for the same money is that this one captures sound when I take a movie clip and the Sony did not. I also found the memory cheaper with more choices than the Sony.

Overall I am thrilled with my choice.

Enjoy!!…

Beware the cons of this camera
I decided to upgrade from my 1.3 MegaPix Olympus Brio D-150 digital camera. The Olympus was my first digicam and I realized I wanted a camera that took better quality photos. The photo quality of the Olympus left me with a lot to be desired as I compared its photos with other cameras.

After reading some reviews and considering the price, I decided the HP 812 would meet my needs for a near pocket-sized, point and shoot, zoom, 4.1 MegaPix digicam. Although I read both positive and negative reviews, I was comfortable with the possibility I may experience some of the minor cons.

The camera itself is the perfect size. The features are exactly what I want. The picture quality wasn’t exactly perfect, but much better than my Olympus. I also bought the accessory kit and the docking station.

The first issue I experienced is that, using ordinary alkaline batteries, I could only get about one dozen photos using flash when the batteries died. This camera is very demanding on batteries. Fortunately, HP includes one set of disposable lithium batteries that last longer than alkaline. With the accessory kit, I also received two pairs of rechargeable NiMh batteries and a recharger.

My greatest disappointment is that the second day I had this camera, after about twenty pictures taken over two days, the camera stopped working. I turned it on, heard a popping noise, then a grinding noise. The lens would not extract from the camera. Either the lens motor or gear stopped functioning. What a shame. I read some reviews which other people experienced similar problems. I understand that a bad unit can come out of a batch of good units, but with my unit being defective after having read such mixed reviews, I decided to return the camera, not for an exchange for a working unit, but for a refund.

I now realize I should simply stick with buying one of the better-reviewed Canon or Sony cameras. It may cost more or I may have to settle for lower MegaPix in order to stay within budget, but the reviews for the Canon and Sony cameras have me convinced they are better quality than this HP 812. I gave this camera the benefit of the doubt, thinking the cons I read in the reviews would not affect me. It takes good (not great) pictures, is small, has good features, and is easy to use. But it also drains batteries too fast and, in my experience, can be defective right out of the box. I do not recommend this camera. There is a reason this is one of the lowest price 4.1 MegPix cameras on the market, and that reason has to do with quality. I will be buying a Canon or Sony now, maybe even another Olympus or Nikon. But unfortunately, I will not buy another HP anytime soon. Thanks for trying HP. It was a fair effort.

Cool camera – MMC cards are not necessarily supported
This is a cool camera and it is small and light ehough to put in your pocket. I carry mine everywhere just in case I want to take a picture. The fact that it uses only two batteries is also an advantage – you effectively get twice the battery life of many other cmaeras. While the Viking MMC cards prompted by David Payne may work in the 812, in general MMC cards are not supported with this camera. According to the manual you should use SD cards for best results.

Amazon.com Review
The HP PhotoSmart 812 is a well-specified 4-megapixel digital camera with a Pentax 3x optical zoom lens. It’s designed as a simple-to-use point-and-shoot replacement, and comes in a compact case with silver finish. While lacking any dramatic aesthetic impact, it does possess neat lines and has an overall feel of a well-constructed camera.

The controls on the HP 812 are straightforward. A power button is accompanied by a shutter button on the top of the camera, the latter surrounded by a mode-select wheel. This enables you to choose between video mode with audio, a time-lapse mode, or straight camera mode. On the back you find zoom controls, located where your right thumb naturally sits. The 3x optical zoom is complemented by a digital zoom to provide 21x total magnification. However, quality suffers when moving to the digital zoom, as with any digital camera.

The menus found via the LCD are straightforward to navigate. You can amend the quality of pictures taken, from one to four stars, with the latter providing 4-megapixel images suitable for print enlargements.

The image quality produced by the PhotoSmart 812 is impressive by typical digital camera standards. However, when stacked against competing 4-megapixel models it doesn’t compare favorably. The depth of field is quite shallow, with only small areas of the picture in focus. The autofocus also struggles in low light. This said, it is worth remembering that other 4-megapixel cameras are often considerably more expensive than the 812.

The HP 812 is designed purely for ease of use and you can configure your images while on the camera to print or e-mail, thanks to the Instant Share technology. This is best served when used in conjunction with the HP camera dock, which is not supplied. This separately available dock enables you to easily share pictures and charges your camera batteries at the same time.

The batteries supplied with the camera are nonrechargeable lithium-ion, which have a decent lifespan. The camera will also take standard AAs in an emergency, but you’ll only get limited life out of these–around five minutes before the LCD powers down. We recommend getting a set of rechargeables, like those supplied with the camera dock.

The HP 812 uses a Secure Digital (SD) card memory for image storage and is supplied with a 16 MB card. More memory will be needed, as the supplied card will only store five pictures at the highest quality. The camera will also take MultiMediaCard (MMC) memory, which is cheaper than SD.

The HP PhotoSmart 812 delivers what it promises, and provides an affordable compact point-and-shoot that anyone can use and take decent pictures with, which, thanks to the resolution, can be printed at large sizes. It will however, struggle to win over any photography enthusiasts with its dearth of manual controls. –Nick Baxter

Pros:

  • Affordable point-and-shoot 4-megapixel camera
  • Very easy to use and download to your computer
  • Good choice for beginners who desire 11-by-14-inch photo prints

Cons:

  • Dearth of manual controls
  • HP camera dock not included, but recommended for easy photo transfer

gphoto2 howto

Fri, 03 Sep 2010 20:19:18 -0400





There is a file labeled install but it doesnt really make sense..... i (sort of) know how to use terminal (meaning i can access it but am lost from there) i just need to know what to type on it. I have xcode on my computer so i can access header files too :) But this is making no sense..... here is the file copy pasted Follow these steps to build and install libgphoto2 from the source code. You don't have to run most of these steps as root, except when explicitly required. In fact, you really shouldn't. In order to get libgphoto2 running after installation, you will probably want to read The gPhoto2 Manual. It is available from the homepage: http://gphoto.org/ http://gphoto.com/ http://gphoto.sourceforge.net/ At lease one of these should work at any time. =============================== Step 0: Preparing configuration =============================== If you have obtained your copy of gphoto2 packaged from a .tar.gz or .tar.bz2 tarball, SKIP THIS STEP. If you have obtained libgphoto2 from SVN, then you will have to prepare for step 1 (the configuration of the sources) by running the autoreconf program. For autoreconf to succeed, you require the following tools: automake autoconf gettext (possibly from -dev or -devel package) libtool (possibly from -dev or -devel package) in versions compatible with each other and with libgphoto2. Most combinations on current GNU/Linux systems work, whereas BSD systems tend to have some compatibility problems. We recommend you call autoreconf like this: $ autoreconf --install --symlink ============================= Step 1: Configure the sources ============================= Now run either one of ./configure --prefix=/usr/local to prepare a tarball source tree for installation in (e.g.) /usr/local ./configure --prefix=/home/me/root --with-drivers=ptp2,canon to prepare a tarball source tree for installation in /home/me/root and for compilation only of the drivers for PTP and Canon cameras. or run ./configure --help in order to find out about more configuration parameters. See Appendix A at the end of this file for some hints on configuring for certain platforms. The following software components are optional, and will improve the libraries' and/or command-line client's functionality if present: libusb (ver. >= 0.1.6a) -- Universal Serial Bus camera support gettext (ver. >= 0.10.40) -- internationalization using shared library gtk-doc -- documentation built in doc/api/ libexif - EXIF tag support Please check the output of the configure script for whether all desired libraries have been detected correctly. E.g., you might have to add the path where libusb-config resides to your PATH before running configure. =========================== Step 2: Compile the program =========================== You will probably be best off running GNU make. On GNU/Linux linux systems, you can run "make", on other systems (such as *BSD), you will have to run "gmake" or something similar. The classic way to compile the program is just to run make or make -jN (if you have N CPU cores) and wait until the source is built. ============================== Step 3: Installing the program ============================== To install the stuff you just compiled by running "make", you can just run make install now. If installing to a directory which is not writable by your current user, you will have to run it as root. This installs the software and documentation into the proper directories on your system. ==================================================== Step 4: Installation is finished - now what do I do? ==================================================== Note that libgphoto2 is not designed to be run by a setuid/setgid program. Running ANY libgphoto2 frontend as root or setuid root or in a similar fashion will open up a SECURITY HOLE in your system! If you run into problems, please read the FAQ (at the website) first. For more general information about how to configure libgphoto2, read The gPhoto2 Manual (at the website). If you have permission problems when accessing your camera, read the chapter on Permission Setup -- you will probably want to create a new user group for the users that are to have camera access and change the permissions of the serial or USB device to match. =============================================== Appendix A: Platform specific compilation hints =============================================== libgphoto2 has been successfully used on many system. Some systems where it has been reported to successfully compile are listed below. Not all, or even any, camera libraries have been tested on these systems, so there may be endian other other issues that prevent some camera libraries from working. Please report any changes to this list to the gphoto developer mailing list. As of this writing, USB support is only available on Linux and FreeBSD as those are the only systems on which libusb is available. General Hints: - If you have build problems in the intl or po directories, try re-running configure with the --disable-nls flag. - If configure stops due to an error with 'test', try re-running configure with the --without-usb flag. - If 'make' reports an error, try using GNU make (often called gmake or gnumake) instead of the make that comes with your system. - If one camera driver has compilation errors, re-run configure with an appropriate --with-drivers= flag to prevent that driver from being compiled. The list of working systems is a little outdated as of 2002-11-20, but we have still left it here as a reference. i386: Debian GNU/Linux 2.2 Red Hat Linux 7.1 Red Hat Linux 4.2 TurboLinux 6.5 Slackware Linux 8.0 FreeBSD 4.3 Try the following to configure the optional libraries: env CFLAGS="-I/usr/local/include" CPPFLAGS="-I/usr/local/include" \ LDFLAGS="-I/usr/local/lib" ./configure (you may also need to append the flag --disable-nls). Use GNU make to build (gmake). Alpha: Debian GNU/Linux 2.2 OpenBSD 3.0 NetBSD 1.5.1 Configure with this command: ./configure --disable-nls Use GNU make to build (gmake). Tru64 5.1A Configure with this command: env CFLAGS='-D__STDC_VERSION__=0' ./configure --disable-nls Use GNU make to build (gnumake).

StrongARM: Intimate+Debian iPAQ GNU/Linux (native gcc) Linux (cross-compiled gcc) Itanium: Red Hat Linux 7.1 (gcc) The following systems have some problems compiling, but may be made to work with some effort: Itanium: Red Hat Linux 7.1 (Intel ecc) There is a bug in ver. 5.0.1 of this compiler tickled by gphoto2 that prevents full compilation. Need better libtool support (newer than version 1.4.2). Red Hat Linux 7.1 (sgicc) Need better libtool support (newer than version 1.4.2). Sparc: Solaris 8 (cc) Sun's cc doesn't support #warning or # or ## macro features, which occur several times in the code. MIPS: IRIX (cc) MIPSpro C doesn't support #warning. Thanks go to SourceForge for their compile farm, and Compaq for their TestDrive program which allowed gphoto2 to be tested on many of these systems. The following instructions are very "generic", and applicable to all makes/models of digital cameras. Sony DSC-V1 camera was used to show all the examples.

Since the vendor supplied Windows driver cannot be installed on Solaris, it needs some effort to make the digital camera work on Solaris 10. The steps are as follows:


  • Bind the device (digital camera) to the ugen driver. Then the ugen driver can talk to the digital camera (device).

    ugen is a generic USB driver, which is part of the Solaris USB Driver Development Kit, presents USB devices to applications through a standard read/write UNIX interface.

    1. Remove the ugen driver from the system, if it was already installed. If in doubt, run the following command anyway:% rem_drv ugen
      Driver (ugen) not installed.
    2. Plug-in the camera to the system; and then run prtconf -v command, to find the device ID for the attached digital camera.% prtconf -v
      ....
      device (driver not attached)
      Hardware properties:
      name='usb-product-name' type=string items=1
      value='Sony PTP'
      name='usb-vendor-name' type=string items=1
      value='Sony'
      ....
      ....
      name='compatible' type=string items=8
      value='usb54c,4e.150' + 'usb54c,4e' + 'usbif54c,class6.1.1' +
      'usbif54c,class6.1' + 'usbif54c,class6' + 'usbif,class6.1.1' +
      'usbif,class6.1' + 'usbif,class6' name='reg' type=int items=1
      value=00000001
      ....
    3. Add the driver alias (usb54c,4e.150 in this example. 054c is the vendor-id for Sony corporation, and 004e is the product-id for DSC-xxx (PTP)) with add_drv command, if this is the first device to be bound to ugen. Run add_drv command, as root.% add_drv -m '* 0666 root sys' -i '"usb54c,4e.150"' ugenRefer to the man page of add_drv for information about -m, -i flags and use of double quotes in specifying a driver alias that contains numbers.

      Note:
      If add_drv command throws an error saying ("usb54c,4e.150") already in use as a driver or alias, that means another device is already bound to ugen. So, to bind the new device to ugen, run update_drv command, as root.% update_drv -a -m '* 0666 root sys' -i '"usb54c,4e.150"' ugenIf update_drv still complains about the driver or alias in use, try to remove the driver and add it again, as explained above
    4. Bind this device (digital camera) to ugen by default that have no driver% echo "ugen-default-binding=\"usb54c,4e.150\";" >> /kernel/drv/uhci.conf
      % echo "ugen-default-binding=\"usb54c,4e.150\";" >> /kernel/drv/ehci.conf
      % echo "ugen-default-binding=\"usb54c,4e.150\";" >> /kernel/drv/ohci.conf
    5. Check /etc/driver_aliases and make sure that the correct compatible name is in /etc/driver_aliases% grep ugen /etc/driver_aliases
      ugen "usb54c,4e.150"
    6. Reboot the machine (only for the very first time)
    7. Plug-in the camera and use prtconf -D to check if ugen has been bound to the device% prtconf -D | grep ugen
      device, instance #1 (driver name: ugen)

  • Use gphoto2, to auto detect the camera. gphoto2 is an application that allows users to operate/download images from digital cameras on Solaris (*nix, in general). On Solaris 10, gphoto2 is available under /usr/sfw/bin directory, by default.% gphoto2 --auto-detect
    Model Port
    ----------------------------------------------------------
    Sony DSC-F707V (PTP mode) usb:
  • Now either use gphoto2 command line tool or gtkam GUI tool, to download all the photos.

    • gphoto2 --help, shows all options of gphoto2
    • gphoto2 -P, downloads all the pictures from the digital camera to the current directory
    • gtkam is also available under /usr/sfw/bin directory, by default

Note that this is a one time only effort, and these steps need not be repeated everytime the digital camera has been plugged in to the system.
