Gear & processing: Both micro4/3 and full-frame gear were used during the trip; but most images were shot with the Olympus OM1 MarkII + Olympus 150-400/F4 with an internal 1.25x. On occasion, a 1.4x was also used. Additionally, the OMD 50-200/F2.8 lens was also used for wider views. For early morning (before ~7AM) and later early evening when light became an issue for micro4/3 gear, I switched to a full-frame Sony A1 MarkII + Sony 100-400/F4.5 1.4x. Nearly all images are 100% crops after exporting from Capture One (where adjustments are made using multiple layers). All images were converted to DNG files by DxO PureRaw 6 prior to Capture One processing. Final crops were performed with AffinityPhoto2. For some files, Topaz Denoise was applied to clean up residual background noise.
