Close-up, Macro, & Micro-Photography of same subject
Jan 23, 2012 15:02:01 #
As a field macro-photographer, I often take a close-up of an full-size insect, because they are too large to capture entirely in a macro-photograph.
Macro-photographs follow, and sometimes micro-photographs to show minute detail. Following are examples.
All three images: Hand-held Nikon D5000 at ISO 400, Nikkor 105-mm macro lens, 1/200-sec at f/22 (#1 & #2) or f/16 (#3), full-sun cross-lighting & Nikon SB-600 Speedlight with O-Flash 3/4-circle Fresnel prism attachment.

#1 - Recently Eclosed Pipevine Swallowtail, male, approx. 1/4 life-size
#2 - Pipevine Swallowtail Eye Spot, approx. life-size
#3 - Pipevine Swallowtail wing scales, approx. 5x life-size

That first shot is stunning, nice job and thanks for sharing your settings.

Very nice! How do you achieve the highest magnification in photo #3? Is that just via cropping of a 1:1 macro shot, or are you using an extension tube? What am I missing? Thanks.

You have missed nothing! This is an extreme crop from a 1:1 image. Possible, because the subject is near-flat, requiring little DOF to hold detail.

When you crop a 1:1 image, How do you determine that the cropped image is 20X? Did you divide the image size of #2 (1116x984) by 20 (55.8x49.2) and make this the image size of the 20X crop of #3 ? I downloaded #2 to get it's actual size but couldn't get actual size of #3

Quite often, I eyeball the ratio, based on subject length & width in known format.
Determining actual magnification ratio on a cropped image can be difficult. Let us assume we are working with a DX format (approx 24-mm x 16-mm).
If we photograph a 12-mm long insect at 1:1, it will fill only half the length of our 24-mm wide sensor. If we crop image to ends of insect, most photographers think we have double the size, but in reality, we have quadrupled the size (twice as wide & twice as high = 4x).
If we photograph an 8-mm long insect at 1:1, then crop as close as possible, we are 9x life-size (3x wide x 3x high).
Measuring pixel area of original and comparing to pixel area of cropped image will also reveal magnification factor
(original area/cropped area = mag ratio), but I find it easier, and fairly accurate, to eyeball ratio.

I see I'm going to have to ad a pen & notebook to my ever growing bag of gear to record sizes of insects & flowers. Thanks for the help. This is going to be a great addition to UHH. I'm glad your at the helm steering us newbee's in the right direction. Thanks again

Actually, the Macro Forum Manager is "at the helm". I just suggest directions to sail.
And the proper term for photographic novice is Noobs!
