TIFF is a container format which supports a collection of other standards and like any container what's in it will be entirely down to what you (or whoever wrote the TIFF export you're using) has decided to put in it. At a guess from the file size your converter has gone to 16bpc/RGB uncompressed. If so then that file size looks about right. If it is ...

If you have experience of sending files for print in the past and receiving prints that are "muddy" and don't match your expectations, the culprit here is "colour management", not the file format. The bits and bytes you upload to the internet are going to be the same ones that arrive at the print shop; the problem is whether they are "interpreted" correctly. ...

scotbb answer is good. I like he is using math formulas, but I will complement that. In my opinion that person on the lab is telling you mumble jumble! Lets put this simple: 16x24 inches at 300ppi are 4800x7200px. Thoose are 34.5 Megapixels. Period. Any picture on a jpg format, regardles you are using the maximum quality will most likley under 20Mb. ...

What about final resolution? [80 megapixels max] How to convert from one to the other? Your print dimensions of 16" x 24" means the aspect ratio of your print is 24/16 = 3/2 (i.e., 3:2). So the ratio of vertical pixels to horizontal pixels h/w = 3/2 (assuming portrait orientation). Let's write that as h = w * 3/2 You know that the product of ...

Here is discussed the same issue. And multipage TIFF is standard, not error. So you should check why your MATLAB libraries do not support multipage tiff or use instruments to remove second page or make matlab libraries work only with first page

Answering to myself in view of the not-sufficiently-good answers, I have found that apple's scriptable image processing system (sips) is able to transform RAW to .TIFF images with only one subfile (the actual image). In particular, I have used the methodology described here: Can I convert raw files to TIFFs via the command line using Apple's converting ...

This is completely valid for a TIFF image. There is in fact no limit to the number of subfiles a TIFF may contain You should either update your routines to support this, or use an intermediate program to rewrite them in a way your code expects.

At your step 5., when you export a RAW file from LR to PS (or when you open a RAW file with PS, make some editing and then save it in TIFF format and import it back to LR), a TIFF get created. However, this TIFF has no sidecar file attached, so you won't find any. So back in LR with a TIFF file, you expect the changes you made to be saved in a XMP file... ...

JPEG is lossy, so the image loses some detail, but the file size may be smaller and compression and extraction can be faster. Wikipedia states, "[It] somewhat reduces the image fidelity... JPEG is also not well suited to files that will undergo multiple edits, as some image quality will usually be lost each time the image is decompressed and recompressed." ...

Compression is something you can see yourself, so I'll focus on interoperability and long-term preservation. The EU's Succeed 2014 Recommendations for metadata and data formats for online availability and long-term preservation recommend "Uncompressed or LZW compression" for TIFF masters (p. 68) and note that «If files are actively managed in a digital ...
