I have a quibble with only one thing you said. You stated that you found the license fee of $300 for Capture One expensive.
Agreed.
Back in 2002 or so, I got a couple of the then-new Canon 1D bodies. I had been shooting with a pair of D30 bodies, and the files were great but the shooting experience left a LOT to be desired. So a 4-megapixel 8-fps camera that could actually autofocus was just what I needed.
But the files were truly difficult, especially using the early Camera Raw plugin to process the raw files. Based on some glowing reviews here, I downloaded a trial version of Capture 1, and the raw conversions were impressive, especially in keeping neutral tones neutral (and not a blobby mess of magenta and green).
Man, I hated the idea of spending $500 for a single raw processing application, and vented about it to my wife. She asked how much I had spent on the 1D bodies. Um, $11,000. Then she pointed out that the C1 was less than 5% of the camera cost, and made the cameras infinitely better. D'oh. I ordered it the next day.
I have since switched to Lightroom for the simplified workflow and the DAM features, but I was very happy with C1 while I used it, and it was well worth the cost.
That said, I had the same issue with Adobe trying to cancel my full CC subscription at work -- once it rolls over, I'm stuck for another year. Grrrr.
