Thanks Walter.  I'd forgotten I had to run LR Plugin manager to get it to work.  All sorted now.
Cheers
Paul

Sorry to ask what may seem like a dumb question, but I've had to reload Lightroom 5.7 & can't remember which file kicks off the Export to Dual ISO feature.
It's the one that processes a Dual ISO shot, deletes the old one & saves the new shot with a Dual ISO suffix.
8bit 240dpi or 16bit & 300dpi?  Colour space to use?
Many thanks

I'm not impressed with this childish prank either.

I'm pleased to report that setting Highlights to -0.5% EV worked for me.
I still sometimes process the penultimate shot in the Snap series, but much less often.

Thanks again for your advice.
Regards
Paul

Thanks A1ex

I've changed highlights to -0.5 EV to see if that helps.  FYI, Auto Snap often takes 3 or 4 shots rather than 2.  Not sure why.
I usually clip green channel, but for some reason it had reset to zero so I've switched it back on again.

If I still get the problem, I'm happy to post some sample images.  Will a link to Flickr work?  Not sure I can insert images here.
I can post unprocessed shots & label them as Auto ETTR 1 & 2 (etc) if that will do?
I shoot in RAW so can post this type or jpg as you advise.

I've been using ML for a while now & wouldn't be without it.  It's a great add on for my 6D.
I use Dual ISO when I need it but use Auto ETTR all the time.

However, I do have a problem with Auto ETTR that I could use some help with:
Quite often I can take a shot where the histogram is right up to the right and not blowing highlights but Auto Snap will take another shot, usually reducing the exposure time resulting in an image where the histogram is quite a way from the right.  On the final shot, histogram on camera & in Lightroom agree it's not optimally exposed (ETTR).
It happens regularly against a bright sky but often happens in less challenging exposures too.  Very often I ignore the final Auto Snap shot in favour of the one before it when processing in LR.
In brief, I take a perfect ETTR exposure & Auto ETTR decides it's too bright & takes another giving a non ETTR image.

I only take still shots, don't use LV & have Mids at 6 & Shadows at 2.  Highlight ignore is at .5% (but I have experimented with increasing this to no avail).
Please don't suggest I switch off Auto Snap & check every exposure as Auto Snap is the method I prefer to use to save time.

Any advice gratefully received.

I'd have been completely stuck without Walter's help.
Thanks again my friend.

Thanks Walter.

Thanks Walter.  That's a very kind offer.
Unfortunately I'm away for the next few days, but would next Monday (11th) at 17.00 UTC be an option?
Regards
Paul

Please could you give me an update on this issue Walter?

No luck using plugin or command prompt I'm afraid.
Details below.
I have to go to work now for a few hours Walter, but I really appreciate your help.

This might be a clue...
After I use the LR plugin or Command Prompt to run cr2hdr, the timestamp on the cr2hdr.exe file is updated.  This doesn't happen with dcraw.exe or exiftool.exe.
See my last DIR post & the one below for timestamps.

By the way, if I convert image to .dng in LR & then process, it does something then renames file to xxxx.dualiso.dng BUT it still has horizontal stripes.

Is this what you mean?  I don't think it is.
I can open a command window as you suggest, but how do I fill it with what happens when I drag the image over cr2hdr.exe, as it happens so fast I can't read it.
Try this:

cr2hdr: moved safeguard from median_int_wirth to kth_smallest_i...

No input files.

GUI usage: drag some CR2 or DNG files over cr2hdr.exe.

Command-line usage: cr2hdr [OPTIONS] [FILES]

Shortcuts:
--fast          : disable most postprocessing steps (fast, but low quality)
                  (--mean23, --no-cs, --no-fullres, --no-alias-map, --no-stripe-fix, --no-bad-pix)

Interpolation methods:
--amaze-edge    : use a temporary demosaic step (AMaZE) followed by edge-directed interpolation (default)
--mean23        : average the nearest 2 or 3 pixels of the same color from the Bayer grid (faster)

Chroma smoothing:
--cs2x2         : apply 2x2 chroma smoothing in noisy and aliased areas (default)
--cs3x3         : apply 3x3 chroma smoothing in noisy and aliased areas
--cs5x5         : apply 5x5 chroma smoothing in noisy and aliased areas
--no-cs         : disable chroma smoothing

Bad pixel handling:
--really-bad-pix: aggressive bad pixel fix, at the expense of detail and aliasing
--no-bad-pix    : disable bad pixel fixing (try it if you shoot stars)
--black-bad-pix : mark all bad pixels as black (for troubleshooting)

Highlight/shadow handling:
--soft-film=%f  : bake a soft-film curve to compress highlights and raise shadows by X EV
                  (if you use this option, you should also specify the white balance)

White balance:
--wb=graymax    : set AsShotNeutral by maximizing the number of gray pixels (default)
--wb=graymed    : set AsShotNeutral from the median of R-G and B-G
--wb=exif       : set AsShotNeutral from EXIF WB (not exactly working)
--wb=%f,%f,%f   : use custom RGB multipliers

Other postprocessing steps:
--no-fullres    : disable full-resolution blending
--no-alias-map  : disable alias map, used to fix aliasing in deep shadows
--no-stripe-fix : disable horizontal stripe fix

Flicker handling:
--same-levels   : Adjust output white levels to keep the same overall exposure
                  for all frames passed in a single command line
                  (useful to avoid flicker - for video or panoramas)

DNG compression (requires Adobe DNG Converter):
--compress      : Lossless DNG compression
--compress-lossy: Lossy DNG compression (be careful, may destroy shadow detail)

Misc settings:
--skip-existing : Skip the conversion if the output file already exists
--embed-original: Embed (move) the original CR2 file in the output DNG. The original will be deleted.
                  You will be able to re-process the DNG with a different version or different conversion settings.
                  To recover the original: exiftool IMG_1234.DNG -OriginalRawFileData -b > IMG_1234.CR2
--embed-original-copy:
                  Similar to --embed-original, but without deleting the original.


Troubleshooting options:
--debug-blend   : save intermediate images used for blending:
    dark.dng        the low-ISO exposure, interpolated
    bright.dng      the high-ISO exposure, interpolated and darkened
    halfres.dng     half-resolution blending (low noise, high aliasing)
    fullres.dng     full-resolution blending (minimal aliasing, high noise)
    *_smooth.dng    images after chroma smoothing
--debug-black   : save intermediate images used for black level subtraction
--debug-amaze   : save AMaZE input and output
--debug-edge    : save debug info from edge-directed interpolation
--debug-alias   : save debug info about the alias map
--debug-rggb    : plot debug info for RGGB/BGGR autodetection (requires octave)
--debug-bddb    : plot debug info for bright/dark autodetection (requires octave)
--debug-wb      : show the vectorscope used for white balance (requires octave)
--iso-curve     : plot the curve fitting results for ISO and black offset (requires octave)
--mix-curve     : plot the curve used for half-res blending (requires octave)
--fullres-curve : plot the curve used for full-res blending (requires octave)

Thanks again Walter.
I've downloaded this file, renamed the old one & pasted this in to BIN folder.
Removed old Plugin from LR, closed LR, opened LR, added plugin & tried again.
Still won't work.
The plugin folder I'm using is cr2hdr.3.0BETA3.3.lrplugin downloaded 24/5/16.
It's the same that worked on my old PC, before I bought this new one (which I'm regretting!).
Is there a more up to date lrplugin file I could try?  Any other suggestions?
Regards
Paul

Thanks Walter.
I couldn't get to it in Command Line (my DOS is a bit rusty) so here's the file:
https://dl.dropboxusercontent.com/u/21483920/cr2hdr.exe

I'm having much the same problem since I got a new PC last week.
Same LR (5.7.1), camera (6D) & plugin (3.0 Beta 3.3).
I've been using Dual ISO plugin quite happily before this.
I export to Dual ISO plugin & am told there's no dual ISO on the shot.  I'm at my wits end here!
I've also tried dragging shots over cr2hdr file with no joy.
Sample shot attached:
https://dl.dropboxusercontent.com/u/21483920/20160703-IMG_8079.CR2
I'd be very grateful for some help here.

Thanks Walter.
Yes, I was on an old download so I've installed BETA 3.3 from your link & it still works WITH EXIF.

Thanks again.

That might well be the issue Chris.  So:
I disabled the old cr2hdr plugin & loaded the new beta version.  Processed but no EXIF.
I removed the old plugin, restarted & installed the new one.  No EXIF.
I then renamed cr2hdr20bit.exe as cr2hdr.exe & it converted OK & with new export interface, but no EXIF.

THEN
Instead of converting to DNG in the import process (I always do this), I just Added them thus keeping them as CR2 after import.
Conversion worked OK WITH EXIF!!!

Thanks very much for your help.

Thanks for the feedback Audionut.

I've followed your recommendations by importing untreated CR2 files & exporting to cr2hdr with the LR plugin.
When I say they are untreated, my usual import routine makes a copy to an external disk & adds the date into the filename, but apart from that, they are as per the SD card.  No lens profile, CA or anything.  I've copied test images from this backup. 
The processed images are renamed with DualISO in the filename, but still have no data attached (EXIFdata?) Lens type, AV, TV ISO etc.  Portrait format shots appear in landscape format.
They were taken in AV mode if that makes a difference but I'll use Manual in future.

Where am I going wrong?  I need the data to appear with the image.

I've taken a few shots in full manual mode as advised.
DualISO settings can be 100/100, 200/200, 6400/1600 or other automatically selected variations, depending on the light.
Does this sound about right?  6400/1600?  I guess this is the same as 1600/6400 isn't it?

I've had a play around with Expo Lock too but can't figure out what, if anything, it's affecting.
I'd like to have the AV fixed (by me), have TV down to the slowest I allow in the ML settings & have (Dual)ISO decided by ML to give a good exposure.
Is this a setting in Expo Lock?  Is it AV>TV,ISO I need to use?

Thanks in advance for your help.
