95 Jun 22 Comment Hi Bernie, love your tiny weed image..
I think spot metering does help to control a bit under outdoor lighting (although the lens getting too close would impact the light source - sunlight). I kinda like the dark background anyway. I will also try that in some situations (as I use evaluative metering most of the time).

95 Jun 22 Comment Great shot, Stuart.. Love the transparent wings and the blurred background.. Perfect for monochrome presentation..
With the 60mm macro lens, you probably have to get pretty close but not to scare the fly away. Amazing.

Tom's denoising using Topaz makes an impacting improvement. Good stuff.

95 Jun 22 Comment Hi Tom, great point and suggestion!
Really appreciate your point of making sure the camera is in parallel with the plane of the subject.. Learned something today. Thank you.
Yes, it was shot handheld.. while touring a botanical greenhouse, without the luxury of more time staying in one spot for displayed flowers or plant.

I did submit that dog sled image to a couple smaller salon contests.. Got 1 bronze medal and 1 acceptance.. Love it.

Totally agreed.. My Pollen grains picture does not have sufficient DOF to keep it all in focused. f/7.1 is not enough.. As Stuart suggested, f/11 may help. As to the flat lighting, I had no control.. But I may have tried using the Viveza 2 tool to improve the picture structure hence yellow and red portions do not look so flat. Good observations. I'll have the lighting in mind when in similar situations. Thanks.

Yes, both you and Pat have good eyes.. I should have removed that green stripe (from the leaf underneath)... my oversight.

Yeah.. my regret on this image is that I did not use a smaller aperture.. to allow more depth of field. Thanks for the suggestion.

95 Jun 22 Reply Hi Pat,
I like your colourful image in the showcase as well; esp the progressive focusing.. from in focus and blurring feeling approaching the top.
The setting of my dog sled image was:
Nikon D750 1/1250s; f/9 ISO @280 (auto); zoom lens @86mm.
Needed higher speed to catch the kicked-up snow. Hard part is to have all dogs showing their faces with expression.
As to the horse photo, usually (like those rodeo pictures), authors would add the kick-up dust to the horse (or bull).
When we go to shoot rodeo pictures, we also shoot some dust from the bull or horse when they kick up violently and save for future use.

95 Jun 22 Reply Ah, thanks, Pat.
That is a great idea to crop it other way.. to bring the audience to the pollen dots.. Appreciate the suggestion.
