Just a heads up, I've recently written a pure-Julia TIFF parser that should handle 32bit grayscale images such fine: https://github.com/tlnagy/TIFF.jl It's still technically a WIP (you'll need to git clone...

@sjkelly do you mind merging this when you get a chance? The CI failure appears unrelated.

It's been a goal of mine for awhile to add automated CI benchmarking to `TiffImages` (ref https://github.com/tlnagy/TiffImages.jl/issues/53) but I'm super busy for the foreseeable future. Does it make more sense...

So I got a chance to play around with the image and this seemed to work: ```julia using TiffImages a = TiffImages.load("channels_24_1_R1.5.tif"); # convert to Gray to discard useless green...

But this is clearly a bug with TiffImages since it doesn't successfully detect the following: - [ ] It appears that the color info is spread across separate slices (!?)...

ImageMagick reports the image as - [x] A palette color image - [x] MSB endianness - [x] Depth at 8/16-bit (??) - [x] Channel depth at 15, 1, 1 bits...

That is currently not possible, but if you want to write a PR. I'll review it and merge.
