Description
Using a 3 float channels TIFF with COMPRESSION_SGILOG is supported by a wide range of softwares
However, I [thought that it was possible](http://www.anyhere.com/gward/pixformat/tiffluv.html) to use a single (Y) plane as well.
I have generated such an image with the libTIFF (and can reopen it).
However ImageJ won't open it
[singleSGILOG.zip](https://github.com/imagej/ImageJ/files/14696606/singleSGILOG.zip)
Before claiming it's a bug or a lack of support : is there a reason for that ? Is such a TIFF *not* correct ?
