Dear listers: I am interested in finding out if there is any way to obtain with digital cameras the effects obtained with film camera when using (1) polarizer filters and (2) infra-red film. Is there any filter, special effect or third party plug-in for Photoshop that can enhance an image in a way that it resembles the action of a polarizer filter ? What about infra-red film photography ? Is the some kind of special filter of plug-in for Photoshop that can resemble the effect obtained when shooting with infra-red film ? Thank you in advance for your help and suggestions. Best regards, -- Dr. Joseph Chamberlain, D.D.S. Oral and Maxillofacial Surgery
