Hi,
Now I made some prints. I may publish my findings on my website or may not, depending on different factors.
Here is what I did:
- Tried to optimally process an image i Process Version 2003. The image was shot under good conditions with a Sony Alpha 900 + 80-200/2.8 APO lens.
- Made a virtual copy
- Switched to Process Version 2010 on the virtual copy
- Cropped for esthetics
- Printed both on glossy A4 paper (uncropped size would be 44x66 cm or 17"x25")
- Printing was done from LR 3B2 on Epson 3800, using 2880 DPI. Output was interpolated to 480 PPI in LR3B2 with medium sharpen for glossy, and 16 bits.
My findings:
- Clearly visible difference in print, with better sharpness in the 3B2 version.
- Some lateral CA is visible in the LR2 image (although CA was reduced), it's entirely gone in the LR3B2 print.
- You need to pixel peep to see the difference, but it can be perceived at arms lengths distance
Other findings:
Noise suppression is now top class. Seems that Sony Alpha images are usable at ISO 6400. I also looked at an old Sony Alpha 100 image that was essentially unusable because of underexposure. With LR3B2 I could make it into a decent image. I clearly feel that LR2B3 represents a significant improvement in high ISO shooting with the Sony Alphas I have.

Bugs:
Found two:
- When in comparison mode and zooming to actual pixels it would not show actual pixels but a coarse preview.
- When I made a virtual copy and tried to open both original and virtual copy in Photoshop I only got one image. I rendered the images in LR as I only have PS CS3.
Here are some downloadable files:

Best regards

Thanks for the feedback. If you get a chance to make some prints, it'd be nice to hear what you find.
