Mike,

I am traveling for the next couple of weeks so replying will be hit or miss.
1. The latest 2016.166.
2. Breeze Browser Pro has no issues displaying my uncompressed arw. Same with Acdsee - I believe they use use dcRaw.
3. Camera name is ilce-7rm2 - when I use Downloader Pro from Breeze Systems I create files names like 20160621_1949_ilce-7rm2_img_01496.arw

Right now my guess is that the Qimage/dcRaw combo is unhappy with uncompressed arw. Let me know how to get you some test images.
Attached is a screen shot showing the issue. I did View, Rebuild Thumbs and the image is correct until the Raw cache finishing rebuilding.

http://www.imaging-resource.com/PRODS/sony-a7r-ii/A7R2FAR2I1600.ARW.HTM shows with the correct colors in Qimage.
Downloaded it is ~42.5 MB vs 83.6 MB for my uncompressed arw. Size matches http://briansmith.com/sony-a7rii-uncompressed-raw-file-size-software-support/
This post used dcRaw to process both arw formats - forum.luminous-landscape.com/index.php?topic=105603.0

At work I am known as the person who finds the 6 Sigma outliers - 6 Sigma is 99.9999% reliable but someone has to make things fail the other 00.0001% of the time. I have been a very satisfied user since 2005 and this is the only wart I have found.

I have sony A7r II uncompressed arw images. In Windows Explorer, DxO, Fast RAW Viewer. the color is good. Even in Qimage initially the colors start out true. But when Qimage creates the RAW cache the color becomes posterized and way off. Clearing the raw cache, trying to rebuild the images does not fix the issue.
Any suggestions? I have never seen this issue before with Qimage. Now I have had it happen with both a Win 7 and a Win 10 system.
If I convert the image to TIFF then Qimage shows an image with the correct colors.

Mike,

FYI, I am finding with Q Studio and the Canvas option mixed results with this issue:
Getting the initial Red border to be the total print size - length + 2 x border + 2 x wrap & width + 2 x border + 2 x wrap.

a. No image on the page, in the queue.
To get the Red border, print area, to be the initial correct size I need to set the canvas size to be the total print size - image + each border + each wrap.
length + 2 x border + 2 x wrap & width + 2 x border + 2 x wrap.

b. Image already on the page, in the queue. I have to reset the Canvas size to the image size.
The initial Red border is then correctly shown as the total print size.

c. Other times I need to bounce back and forth a couple of times between A & B to get the Red border to be the total print size.

For the final printing the queue shows:
a. Red border is the true canvas size, size to the print the image;
b. There is a cross hatched border for the mirror;
c. There is a dotted line for the wrap.

It seems that Qimage is the only image management program that I have that still does not support shortcuts.
I prefer to keep my image in one place then make shortcuts to the final folder instead of copying the image.
