General / Sony Alpha 7R calibration (full frame sensor)

« on: October 19, 2016, 04:23:07 PM »

Hello All,

I have been using an EOS 70D to capture images of bones on a turntable. Yesterday the shutter packed it in (in fairness I shot about 20k images in the past few weeks), and I have been loaned a Sony Alpha 7R while my EOS is being fixed.

The Sony Alpha is a full frame sensor. I have included a number of scaling items in the shots to enable bone measurements later, must I  calibrate the Sony in processing? If yes, how?

Cheers

General / MASKING AND MANUAL ALIGNMENT OF CAMERAS

« on: August 10, 2016, 05:32:07 PM »

Hello,

I have taken a series of photos of an item on a turntable. I took a blank 'masking' image at the start, but, despite cut/pasting the mask image's file name (IMG_XXXX_mask.png; Method:from background; Operation:replacement) and including the correct file origin, the file pathway is not recognised and 'can't load...'. I am sure the solution is very simple but any help is appreciated.

Following the failed masks I masked manually.

Most cameras aligned well but there are a few that did not. Furthermore, the chunks did not align as accurately as I'd hoped.

I have read through the forum you can use markers to manually align cameras that have failed to register in the initial 'Align Photos' stage. There is also an option to manually align chunks in a similar manner.

Is this feature available in the Standard edition? I cannot find n option to set markers anywhere.

Thanks in advance.
