75 Jun 23 Reply I would respectfully disagree with your opinion on diffraction Charles. I use top quality glass for emount and I can point you to literature as well as my extensive testing that details the laws of physics and the angle of light hitting the sensor. Let me know if you would like additional information on the subject. Right now I'm in Yellowstone and have limited connectivity. Jun 12th
75 Jun 23 Reply Murphy, I try to keep my aperture below f11 in order to avoid diffraction which IMO affects overall image quality. In this case going from 5.6 to 11 with an ISO boost would have been preferable as you suggest. I try to keep as close to base ISO as much as possible in order to maximize dynamic range in the Sony sensor, but as you know trade offs are part of every images puzzle.


From the comments received it seems a consistent exposure and sharp focus would be the preferred technique for this type of subject. A focus stack would be in order perhaps. Thank you everyone.

75 Jun 23 Comment Very nicely done with an excellent use of supplemental light. I really like how the bottom of the blossom fades into near shadow. Well done. Jun 9th
75 Jun 23 Comment As mentioned a very nice example of stacking and a nice combination of a warm subject with a cool background. I would have liked the very closest petal to also be in focus and this is perhaps the easiest part of the subject to miss focus when performing a complex focus stack. Jun 9th
75 Jun 23 Comment Judy, a very nice dual subject and nicely exposed with white and yellow very easy to overexpose. I don't find the bottom rail distracting and for me provides a nice platform for the eye to move into the image. I do agree the background exposure does compete with the subject and should be either blurred or darkened. Jun 9th
75 Jun 23 Reply Thank you everybody. This image was captured on a tripod without OIS, manually focused and with a remote release. I posted this to get some ideas on how to capture an entire flowering shrub with a busy background. Creating a pleasing image of this sort has not been my forte and I am hoping to get some ideas for future projects. I recently switched my email browser and Vincent was kind enough to point out how I had the settings wrong related to resolution. Jun 9th
75 Jun 23 Comment Being from this area, I have photographed many of the Skunk Cabbage blooms in the spring. Velvia was such a great film with the colors unmatched. I use an Epson Scanner and I have also used a Fuji GFX 100s to go from analogue to digital. Tedious work with dust and color casts, so have not done much in the last few years and have focused on taking digital files into the darkroom for alternative printing.

As to the image, I like the composition and lighting, my only critique is the image is a little tight on top for me, otherwise very nicely done.

75 Jun 23 Comment The composition is nice and the dof of field well done, but the blown highlights are still a little distracting. My submittal for this month has the same issue. You might try to duplicate the image and drop the exposure then combine them again in PS with a mask on the dark exposure paint in the highlights. I did this on my submittal and it still has some blown areas but is improved. Jun 1st

90 Jun 23 Comment I like the B&W version because the contrast is better and the limited colors in the original do not really add to the story. Jun 1st
90 Jun 23 Comment What an exotic subject. Good tones and well done. I like the image as is. Jun 1st
90 Jun 23 Comment I like this peek-a-boo image. Good focus, my only comment would be to try and darken the foreground and background highlights. Jun 1st
