![]() ![]() ![]() I have some examples (proms/surface from one exposure), but need to find them back (too many files, spread over different computers because lack of disc space). One thing that might happen is that stacking software might detect detail easier, but I doubt. That is exactly the same as applying a gamm correction to your image. On that image the ZWO driver applied the gamm correction (altering the signal). That is the final image that will be saved to disc. A ZWO cam passes the data to the computer (either 8 bit or 16 bit). What was the problem with delayed sequence and gamma? Sound strange to me. Yes, I was using Genika Astro for the last years (handy SSM trigger) but as you said ZWO gamma is not supported and without that I have an error message when attempting to make a delayed sequence for a time laps. (Some cameras have a hardware gamma adjustment, and these may be usefull to get more dynamic range, but in this case we are talking about ZWO cams) You adjust the signal level and risc loosing data that can't be recovered in the final image. For cameras with software adjusted gamma it is not a good idea anyway. So no need to fiddle around with gamma recording settings. If you only need it for focusing: every capture program I know has some functions to alter contrast, brightness or gamma on the display without touching the recorded image. It might slow down capturing (while more processing is done, so on older not so fast computers. You can download Gamma Control free here.First of all that Gamma function was done in software, so everything changed there, can be done afterwards in post in the same way. If the image on your monitor is too bright or too dark, Gamma Control makes it possible to adjust this setting immediately from your keyboard. It would have been useful if the application had made it possible to control other aspects such as colors or contrast. Gamma Control is free, and it can be installed in a matter of seconds. While running in the background, the application will not have any impact on your computer's performance, even if your hardware is out of date. If another program deactivates the hot keys, they can be enabled again by clicking an option in the tray icon's context menu. ![]() It is also possible to apply the last used gamma level and put the monitor in sleep mode, also with shortcut keys. Using simple combinations on your keyboard, you can increase or decrease the gamma level or set it back the way it was. If you click the Help button, beneath the options, a new window will appear, where you will find a list of shortcut keys for all the adjustments. These options can be enabled by clicking the check boxes next to them. The application's small interface consists of three options for setting it to run at Windows startup, minimizing the interface automatically at startup and saving the gamma adjustments. The setup file is less than one Mb large and you can install it on most Windows versions. Gamma Control can be installed like any other application, by going through a wizard's simple and straightforward stages. This simple application, called Gamma Control, will let you adjust the gamma level on your screen with simple hot keys. Windows does not offer any help in this regard, so you can only turn to third party software. Sometimes, the image from some movies may be too dark to understand anything from it and you will end up playing with the monitor's buttons, navigating through a clumsy menu and trying to adjust the gamma settings. ![]()
