How many megapixels are compressed xt2 raf files?

In faststone image viewer my xt2 lossless compressed files read only 2.46 MP.

But if I export them from c1 to cs6 they read in 'image size' as 4000 pixels by 6000 pixels which is 24mp.

Me not understand ;P

I guess what FastStone shows you when you open RAF file is its embedded JPEG preview instead, being on the smaller side (as reported, 1920x1280).

When you open RAW file in a RAW editor (as C1), you get to see actual RAW file being "developed" at its full resolution (6000x4000), and that is what you get to export, too.

p.s. Even (some?) RAW editors tend you show you JPEG preview image first, until RAW data is being processed in the background and ready for showing. Depending on how good editor is in replicating in-camera RAW to JPEG engine (but what your default editor settings are, too), you may see (much) more or less difference in what JPEG preview was showing and what actually processed RAW file shows once it appears.

In Faststone, go into the setting menu.  In the "RAW" tab, change setting from "Embedded Preview Image (Fastest)" to "Actual Size (Slow)" and you will see the full raw file instead of the JPEG.

Unfortunately Faststone doesn't convert lossless compressed Fujifilm files.

Yourself and the above poster have provided me with the answer, thanks so much.

I also learned after some research that the lossless compressed really is lossless due to compression algorithms making the files smaller not loss of data.  I won't go into that as it is another topic but very happy to know all of this

Thanks
