Hi Bob It is a bush but to be honest, I haven't the foggiest as to what kind. I've just now put the question to the owner and her neighbor and will let you know asap. The leaves look a bit like those of a succulent in terms of surface properties but they're not. I'll post a few gear pics in the same gallery later today and add some explanations to this thread. The key to the image is to match planes (subject, lens and sensor) as commanded by Scheimpflug's rule, i.e. make them all meet in one imaginary intersection (the word point doesn't quite hit the nail on the head) which will then cause the focal plane to be level with the subject plane. In this particular instance, IQ suffers quite a bit from the extreme tilt (27 of 30 possible combined angular degrees) as well as from aperture bending. My mistake BTW, image was taken at f/67. I'm also sure with a bit of practice I can do better than that but right now it is trial and error. Please have a look at this URL, the URH image pretty much shows my gear as well as the principle of it all except I did it at close range of about 5-7 cm. http://www.novoflexkreativdasbuch.de/pageID_8784247.html Cheers Ecke -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
