"Bringing Cameras To All ~ BCTAfour" is for wide spread sharing of photos by Photo Trekkers from the first three BCTA groups (see "Our Sponsors" in the left hand column), all of which use Meetup's "small group" format. However, some leaders also cross post with large groups, non-meetup web sites, e-mail lists, &/or even snail mail, so BCTAfour provides a photo sharing forum, since only the photo posters themselves need join here.
Lookie-Lous: Anyone (you do not even have be a member of meetup, much less one of our BCTA groups) can view the photos, individually or in slide show format.
Downloaders: Anyone may download any photo, FREE, in any of five sizes/formats: Thumbnail, Small, Medium, Large, Original; just click on "All Sizes" above the photo in which you are interested.
Uploaders: Leaders (and invited members) of the other BCTA groups (see "Our Sponsors" in the left hand column) are eligible to also become "Photo Trekkers" and upload photos to this site, "Bringing Cameras To All ~ BCTAfour." SEML members are also eligible for invitation.
