I have also performed the direct bias injection modification, and some comparisons to amp-on long exposure settings I have done some sample imaging to record the effects of gain/brightness settings, and this can be viewed here Here, you can see the difference between amp-on RAW mode and amp-off RAW mode with direct bias injection, again with identical imaging parameters.

This is a FREE modification that DOES NOT INVOLVE taking your camera apart again after the LX mod has been done!Ĭomparison: AmpON RAW mode vs.

These resulting images were not adjusted or modified in any way! The image that appears when you mouse-over was produced with the camera in RAW mode. This is a stack of 5 images with the following parameters:īoth images were taken under identical conditions, only moments apart. elimination of "black holes" and "ears" artifacts adjacent to starsĬomparison: Normal vs.individual hot pixels instead of bloated hot pixels.This results in a major improvement in the quality of images. (with its processing power) is much more capable of carrying out this function after the fact. RAW mode changes the camera so the debayering (color interpolation) is no longerĬarried out, and RAW, unprocessed pixel values are sent to the PC. This is a firmware change in the camera, and is accomplished with a simple programĬalled WcRmac. One of the EASIEST ways to improve your images with any LX modified camera is by using the camera To achieve LONGER time exposures, you will need to consider direct bias injection (seeĪnd possibly peltier cooling of the CCD sensor. The properties dialog would have you believe it's 1/25 sec). In essence creating a camera with 300x (a 30,000% improvement) the sensitivity that it had before (maximum exposure of the unmodified cam is 1/5 second at 5fps, even though hot pixels in the camera (can be counteracted by dark frame subtraction and active cooling with a peltier module)Īfter performing the long exposure and amp-off modifications, you can realistically expect to have time exposures of up to 60 seconds in length,.
