PhaseOne XF LCC workflow
« on: April 21, 2019, 11:44:36 am »

Hello

I read in other thread  > https://forum.luminous-landscape.com/index.php?topic=129347.msg1103589#msg1103589 following.

What I do I take a picture of the sky at f/16 after the shooting to use as a dust reference. That will be the image with the most dust spots. I calibrate the dust removal on that image and apply the same to the other images from that day. Typically, dust spots do not move between pictures.

What is the best practice before or after the shooting.
a) Using a LLC plate? I have it.
b) Using high aperture, f20 or higher?
c) Using distance infinitely?
The result I can use in COP > LCC to delete the dust.

Hi Jochen,

The LCC should be taken with the same aperture and focal distance setting as the actual image(s).

When you refocus, the shadow of the dust may change shape/density a little, and using a narrower aperture will give the dust a sharper contour. When you use the same settings for both the images and the LCC, then the dust shadows will match in brightness and contour.

It's best to take the image and the LCC at roughly the same time, to avoid the dust moving on the sensor in the mean time.

Cheers,
Bart

Thanks Bart.
I will carry out this by next shooting.
