J'ai ce massage d'erreur Pix lorsque je tente de stacker mes darks - bien sûr mes images sont en 16bits.
Quelqu'un a déjà eu le pb ?
Zero or insignificant signal detected (empty image?)

Salut Franck,
Tu peux nous montrer un dark ?
J'ai jamais eu ce message...

J'ai déjà eu ce message ... en oubliant de régler correctement à 16 bits
