Hi Chris
Hope you are well. Anyways, to answer the questions:
1) Could you send me a screen shot of the issue? The only thing I can think of is that the gain / offset values may be set too low and so the histogram ends up 'below 200'. I should probably change the histogram for 0 -> 65K on the horizon camera anyways.
1b) When moving the black and white bars, the Gamma bar will keep the same ratio as it had before, therefore it'll move with the sliders.
2) For binning on the horizon, I simply add the pixel values together, which will create a mono image. We've actually discussed the idea of adding a special option for 2x2 binning, where it actually creates a single colour pixel from the 4 pixel square. This would be really handy in the Infinity software as it'll significantly reduce the memory usage, whilst keeping a colour image. I'll keep this idea high on the list and let you know what happens.
3) The 'Quick Display' mode is something I would encourage you to use with the Horizon camera. If it's switched off, then the infinity software will draw every single pixel of the final image. This is fairly wasteful as realistically, you aren't going to see every single pixel. So instead, when the option is switched on, the software makes a smaller image which gets drawn instead. If you toggle the option on/off you'll be able to see the difference (it's subtle, but you'll notice a slight change in pixels). However, with the option switched on, it takes a much shorter time to draw the image, so the performance is much better. At the moment, it only bases it on zoom level, so if you zoom in far enough, it'll still draw the whole image. However, the next step here is to just draw the area the screen is looking at. This has been high on the list for a while, so I'm hopeful I'll add this in before too long.
I hope that helps.
Chris.
