I subscribe to several Flickr groups, some of which are strictly devoted to film. Fine, I shoot film and digital, and develop my own BW. Two of the sites have just announced that NO DIGITAL IMAGES of any sort will be permitted, on pain being banned from the group. This implies that, for example, if I wish to explain and demonstrate how to convert a Pentax 645 film insert from 220 to 120, or vice versa, I have to shoot on increasingly expensive film, process it, and then scan the negative in order to do what could be done digitally in moments. Yes, I could describe the process in words, but the addition of pictures makes the process much clearer and less likely to be misunderstood. Does anyone else feel that this position by the Administrator is a little extreme?
