Capture 1 - Rodenstock distortion correction
« on: June 27, 2016, 11:39:07 am »

Hi all,

A quick question.  Previously we had used to use the Alpa photoshop plugin to correct distortion of the Rodenstock lenses
I feel like I remember reading somewhere that C1 had incorporated this into V 9?

If so, can you let me know where to find it and if there is any difference in using it to the Alpa plugin.

Cheers

You probably read about it from me :)

Biggest differences:
- done at the raw stage (better quality, better workflow)
- easier to batch apply (copy-apply)
- not every single rodenstock is supported (though most are)

Supported Rodenstock lenses:
HR Digaron - S 5.6/23 mm
HR Digaron - W 4.0/32 mm
HR Digaron - S 4.0/35 mm
HR Digaron - W 4.0/40 mm
HR Digaron - W 4.0/50 mm
HR Digaron - W 5.6/70 mm
ALPA HR Alpagon 5.6/90mm

Thanks Doug!

The interface is a little different to the Alpa, so I'd just like to confirm with you the inputting of  movements:
A Left shift of the back is a -
A Right shift of the back is a +
A Fall of the back is a -
A Rise of the back is a +

So if I was to do a pano stitch of a building it would look something like this:

Left Hand Frame
+10 shift.
-10 Fall

Right Hand Frame
-10 Shift
-10 Fall

Appreciate your time.

Cheers
