Title: Capture 1 - Rodenstock distortion correction
Post by: alatreille 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

Andrew

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
