Having seen the news: www.bbc.co.uk/news/article... thought I'd share a cilia movie captured at UCL GOS ICH with Eriomina Shahaj & Vanesa Papastavrou using simple DIC on a Nikon Ti2 with DIC at 60x1.4. 500 fps here slowed down 20 times. Processed with Nikon's denoiseAI and an unsharp mask in Fiji.

I've been working on a fast, high-ratio image compressor to try and alleviate the data storage issues myself and some of my colleagues have recently been facing. Before I 'release' version 1, it'd be great to gain some feedback regarding performance and missing features. github.com/jdmanton/rad...
