I have uploaded a couple of short F55 raw sample for you to play with. The exposure was deliberately pushed to it’s limits on these clips so you can have a go at grading them. Resolve Lite (free) can be used with the footage.

If you find the footage useful please make a small donation to go towards the cost of hosting the files or buy me a coffee. All donations no matter how small gratefully received.
