Frequently Asked Questions

QuickPHOTO Software Suite

Can we try QuickPHOTO programs and extension modules before purchasing, how is the program licensed?
  • You are free to download and try any of the QuickPHOTO programs for 30 days without other limitations.
  • All extension modules support free demo mode, that is not time-limited, but a watermark will be inserted into the created images or videos. Extension modules require QuickPHOTO program for their installation – even a 30-day trial version can be used.
  • You can install a trial version of QuickPHOTO program to a computer where QuickPHOTO 2.x program is already installed. The programs and their settings are independent.
  • If you purchase the program and eventually extension modules, you will receive a dongle containing the corresponding licenses. Once the dongle with appropriate license is found, the program and extension modules will be automatically activated.
  • Only one computer can use the license at a time. If the computer should be replaced, it is possible to transfer the dongle with the license to a new computer. Should you need additional licenses, contact your QuickPHOTO software supplier for pricing.

How to setup a camera control via TWAIN interface in QuickPHOTO 3.x programs?
What is TWAIN interface?
TWAIN is an applications programming interface (API) and communications protocol that regulates communication between software and digital imaging devices, such as image scanners and digital cameras. This interface enables the QuickPHOTO programs to control also the third-party cameras, which are not directly supported in it.
Procedure of installation:

  1. Connect and install your camera according to the guidelines of its manufacturer.
  2. Download and install a TWAIN interface for your camera from the website of the its manufacturer (if it is available). Always install 32-bit version of a TWAIN interface, even if you use 64-bit version of Windows® operating system. If you would install 64-bit version of a TWAIN interface, it would not be available in QuickPHOTO programs.
    Note: for some cameras, the device drivers and TWAIN interface installation can be performed by a single installer. For more information refer to the information provided by the camera’s manufacturer.
  3. Install the QuickPHOTO program and during the installation select the Imaging Devices Controlled via TWAIN Interface option:
  4. Run the installed QuickPHOTO program and select the TWAIN Device option from the Imaging Devices menu:
  5. Select Source system dialog window will appear listing all the installed 32-bit TWAIN and WIA interfaces. You should be able to see the TWAIN interface for your camera in the dialog window. Select it by mouse and press the Select button to confirm (use only TWAIN interfaces, not the WIA ones).
  6. Click the camera icon in the QuickPHOTO program’s toolbar or activate the Open Imaging Device Control Panel… option from the File menu. A window with camera’s live view and controls should appear. After acquisition, the image should appear in the main window of the QuickPHOTO program. Control window of the camera remains open, until it is manually closed. This behavior can be changed in the program options (Edit>Options… in Hardware Devices>Imaging Devices section in Properties of TWAIN Imaging Devices Control Panels part).

How to find out if QuickPHOTO will work on a new computer or with another operating system?
  1. In general, the QuickPHOTO programs themselves support Microsoft® Windows® XP/Vista/7/8/10 operating systems.
  2. Besides that, check support of your imaging device in the compatibility table of imaging devices with operating systems.
  3. If you have OLYMPUS® consumer or DSLR camera, check support of your device for live view display in compatibility table of devices for live view display with operating systems.
  4. The program is protected by a dongle which needs to be connected all the time you use the software. If you have an LPT dongle (parallel port interface), you can replace it by a USB dongle if required. For pricing, please contact your QuickPHOTO software supplier. The ECP or ECP+EPP mode of the LPT port should be set in the computer BIOS. We do not recommend the use of an additional card with LPT interface.
