A different interpretation of my close-up photo

Thank you Mark.

Still playing with Lab mode. Will try some close-up flower photos that I have posted here a few months ago.

Thank you Mark

It is an enjoyable hobby. As is playing with Photoshop. I plan to play with the last photo of the butterfly to see what variations I can produce in photoshop. Just having fun.

Thank you for your comments. All Photos were taken hand held as I sat in the chair. I braced my left arm against my side and held the lens with my left hand. I continually pressed the AF-ON button to AF the camera as I search the lavender plants for the bees and butterflies. I had set the D500 camer...

Close-up Bees & Butterflies Enjoying Lavender nectar

After my post (Aug. 8th) on the resolving power of the Nikkor 300mm f/4E PF lens and attached Nikon 17E II Teleconverter lens, mounted on a Nikon D500 camera, I stopped doing indoor resolution chart testing. Instead, for the first time since I purchased this equipment, I took this Nikon camera and l...

Thanks Chris I have nothing more to add. I was going to see what the Nikkor 300mm f/4E PF with the Kenko 68mm extension tubes (produces 1:2 photos at 48 inches) would produce. But from reading these posts I have a cheap lens and should buy the more expensive Nikkor 300mm mentioned above. However, I ...

Boy, has this exploded into something other than what I originally posted. This discussion should have been another post. I no longer have anything to contribute. Keep it going among yourselves.

Rik & Lou This resolution chart was printed on a Epson R3000 printer which use 8 inks (5 colors and 3 blacks). It prints black with these 5 color inks. I am thinking about printing the chart with just the 3 black inks which I can do with this printer. Rik, lets remember dimensions. The white hole yo...

The two photographs are of the same printed resolution chart, with the chart located in exact location (did not move the mounted chart), and under same Ott light located in the same position relative to the c...

Thanks Lou

I too am puzzled. I looked at the larger bars in the photos and found the same results, desaturation of colors. The only explanation I can think of is these colors are extremely small and may look like chromatic aberration to the lens. But why replace the colors with black?

1:2 photo - Nikkor 300mm+17E TC versus Sigma 180mm lens

The following is long reading, but for those that own the colored corrected APO MACRO Sigma 180mm f/2.8 EX lens or those who are thinking of buying this lens, there is a very interesting result that you should know about this lens, if you do not already know. On July 7th, I posted the 1:2 photo reso...

Lou and Robert

Later today (its 6:20 am here in Sequim, Washington) I will finally post my 1:2 photo comparison between the Nikkor 300mm lens + attached 17E II TC lenses to the Sigma APO MACRO 180mm lens. There was an unexpected result with the Sigma lens which may be very controversial. I expect Robert to chime i...

300MM F/4E PF + 20E III TC, 1:2 RESOLVING POWER AT 4 FT

On July 16th, I posted the resolving power of the Nikkor 300mm f/4E PF ED VR lens with the Nikon 17E II teleconverter attached between this lens and the Nikon D500 camera. This combination gave a near 1:2 photograph at a close-up working distance of 48 inches. The measured value was 1:2.3, that is, ...
