When I use Luminar 4 as a plug-in to Lightroom, there is a choice as to copy the file as a TIFF, PSD, or JPG. TIFF is the default. Doing so seems to take up a lot of storage space. What is the advantage, if any, of using TIFF over JPG when copying to L4?
A TIFF file can be 16 bit while a JPEG file can only be 8 bit. A 16 bit file is going to be a lot bigger than an 8 bit file. A JPEG must be lossy compressed such that data in the image is lost to achieve greater redundancy and so increased compression. A TIFF file does not have to be lossy compressed and so all of the data is retained.
