I appreciate the comments, but the photo above was about 1 1/2 yrs ago. I'll take some present-day photos of it soon after the 7th bud has some time to get a little larger. I'm hoping my photog efforts are somewhat improved at this point. The shape will be similar, but one of the blooms is not pointing in the ideal direction, but still I don't think it will look too bad. You'll see what I mean.
I will welcome any suggestions on how to improve the plant or the photos. I like more natural light photos if I am able to take them, and since that photo above, I've learned more about the aperture settings (f stop), for light / depth of field, and how to use the ISO if too dark, or even better, to use the 'exposure compensation' slider, with the live view display to see how the subject should look prior to taking the photo. This compensates for over / under exposure cause by a too dark / light background. I'm even getting better at more correct color renderings of vivid magenta-purple blooms like some of the C. luddemanniana have, by using the white-balance to adjust the color in the photo. (old dogs can learn new tricks if properly motivated)
