Their website does say that you can pay per image at $1 per image. I am in the opposite boat though. I could see this having a very significant effect on photogrammetry but I would need to process a few thousand images at a time which would not be very feasible with their current pricing model
To the developers. A very promising piece of software for a VFX supervisor like me. BUT, please reconsider your pricing tiers and introduce a per-image price. We are a pretty large facility, but I can only imagine needing about 1-10 images a month at the very most. It's like HDRI's - we buy them all the time, one at a time. They need to be individually billed so a producer can charge them against a particular job.
