SharpCap 3.2 (and older versions) work like a video camera – they take pictures all the time. This can cause problems with cameras that take a long time to transfer the image to the computer, like large CCDs and DSLR cameras – SharpCap may not respond during the image download time and when that is complete a new image will be captured and start the download process again.
For these cameras, please use SharpCap 4.0. Before opening the camera, deselect the ‘Live View’ option in the toolbar so that it is no longer highlighted blue:
Once you have turned off ‘Live View’, open the camera. In this mode, SharpCap will only take images on request (if you press ‘Start Capture’ , ‘Quick Capture’, ‘Snapshot’, etc.). You can also take an image without saving it using the ‘Framing Shot’ button.
The simplest way to do this is to hold down the < CTRL > key while the camera is opening – this stops SharpCap from loading any previously saved values for the controls. It’s probably a good idea to close and re-open SharpCap before doing this.
You can also go to the SharpCap Settings and untick the box labelled ‘Automatically restore the last used camera settings when opening a camera’ – this will stop SharpCap from re-using the previous settings permanently.
If you zoom in on the image you might see a grid pattern of brighter and darker pixels at the pixel level. The colour is encoded in this pattern – it’s called a RAW image. SharpCap understands this and converts the image to colour before displaying it.
In order to see your saved images in colour you need to use an image viewing or processing application that understands RAW images and can recover the colour information (this is called ‘debayering’). For more information read this thread in the forums and this document.
