All what you wanted to know about using flipper probes @spirochrome @matile_group for cell biology and didn’t dare asking is in: https://t.co/MOC98W09ld Thanks to all co-authors and colleagues, thanks to @CRoffay & @vincent81196538 for their great work!

Ok, here starts a little tweetorial on everything you should know on 'Gamma Correction" and why it matters...
Just realized how misunderstood and under-utilized gamma correction is in microscopy. Let me state this here provocatively, get some comments and then I will explain what I mean and why it should be used or at least considered every time we publish microscopy images... 😉
