Hi Phil.
I thought I'd have a go with raw files with my Fuji HS30.
I'm getting some numbers I don't understand from the raw RAF file. The converted jpeg size is as expected but I am seeing four sizes for the RAF file.
First, the Silkypix raw file converter. Looking at their exif display for a raw file I see:
width 3248 height 2436
I go into "development" and it tells me that the original is
4608 x 3456
and that it will produce a jpeg of that size and notes it is 100%.
Then exiftool gives me, for the RAF and the jpeg
exiftool DSCF0165* -a -G1 -s -imagesize -RawImageFull*
======== DSCF0165.RAF
[Composite] ImageSize : 2048x1536
[RAF] RawImageFullSize : 3328x2464
[FujiIFD] RawImageFullWidth : 3328
[FujiIFD] RawImageFullHeight : 2464
[RAF2] RawImageFullSize : 3328x2464
[FujiIFD2] RawImageFullWidth : 3328
[FujiIFD2] RawImageFullHeight : 2464
======== DSCF0165.jpg
[Composite] ImageSize : 4608x3456

Hi Alan,
First, let me say that extracting the dimensions of a FujiFilm RAF image is not simple.
Second, I should note for anyone else reading this thread that the X-E1 image dimensions are not reported correctly by ExifTool 9.13. This will be fixed in 9.14.
And now on to your question...
When I develop a HS30 RAF image in Adobe LightRoom, it gives me a 4608x3456 pixel image (same your Silkypix-developed image).
However, when I use "dcraw -i -v", I get this:
Thumb size: 2048 x 1536
Full size: 3328 x 2464
Image size: 3262 x 2464
Output size: 3262 x 2464
And dcraw generates a 3262x2464 developed image, as it stated in the "-i -v" output.
ExifTool uses dcraw's technique to determine the size of RAF images. For historical reasons, the "ImageSize" ExifTool reports is that of the embedded JPEG (same as dcraw's "Thumb size").
So I agree with you that there is something funny going on, but I don't understand what.
I have sent an email to David Coffin (dcraw author) to see if he knows what is happening.

Phil, I don't know how you maintain your sanity dealing with this stuff!

You're making some assumptions here that may not be true... ;)
