DIY Cheap CFExpress Type B card

January 1st, 2025

One of the good things about cameras that take CFexpress type B cards is that type B cards tend to be much cheaper than equivalent size type A cards.

But if you go the DIY route you can make your own CF Express type B cards even cheaper. For example, my 2TB card only cost me about $110. Compare that to Sony's 2TB CFexpress Type A card, which sells for about $1400. Or even Angelbird's 2TB Type B card, which sells for around $800.

Colour Infrared Filters for Video

November 2nd, 2024

In this post I'll be looking at achieving various colour effects with different infrared filters when shooting video. This is a follow-up to my previous post where I looked at a variety of infrared filters and the effects you can get when shooting stills.

When shooting RAW stills and using Adobe Camera RAW, you often need to use special profiles to white balance infrared images because the white balance adjustment required is so extreme. So I wanted to see if the white balance adjustment needed would be too extreme to allow for usable video or not. And also whether the same hue adjustments and colour channel swaps could be applied to video to get the same colour effects in video that we see with stills.
