White dots in HDR photos after using Helicon filter

Unread postby Feri » 08.02.2009 10:05

Hi
I use PS CS3 with Helicon filter plugin for processing HDR photos and I am getting white dots at 300 magnification on the HDR picture. What is causing this and how can I remedy this or avoid getting them?
It mostly happens on photos taken at night light and it happens after tonning with Helicon filter plugin and converting the 32 bit image into 16 bit image in CS3. I will attaqch a snapshot of the white dots.
I appreciate your help.
Thanks
Feri

It looks like an overflow problem in Helicon Filter. I would need the source image and description of the action applied to in in HF and PS.

i get the same artifact. when i go into the individual images, i will find a single oddball pixel that gets repeated as i move the camera closer and closer to the subject. since it is such a definable item, they all get into the final image.

oops -- i forgot to mention the fix. it is very simple. if you are stacking just a few images, find the aberrant pixel prior to running hf. otherwise, use the retouching feature. it's easy to do unless it's located in a sensitive area.

A sample image still would help us to fix this bug.
