This gave me about 3 to 5 minutes for the photography before they warmed up too much and would start moving. I put them in the 'fridge for 20 minutes! Note, not freezer which would have killed them.
Now, your question, keeping the creatures still for long enough to do this. the wasp) was put on this platform and so I could make several images. I don't know what the correct English word is for that but in essence, by turning a knob I could advance the platform by 0.2mm at a time. Focus stacking is a technique designed to achieve a deep depth of field by blending (or stacking) several images together. So I made up an aluminium plate for the tripod which carried both the camera and a movable 'platform'. This mounts the entire camera on a rail (attached to a tripod) and the rail allows the entire camera to slide forward/backward (my rail has about 11 cm worth of travel). Depth of field is minimal at these magnifications, submillimetric). If you are interested in focus-stacking specifically for macro photogoraphy, the common solution is to use a 'focus rail'. However, working distance is minimal and the whole caboodle is very sensitive to vibration (even on a good Manfrotto tripod). The reproduction ratio is then the ratio of the respective focal lengths thus 105/24 ± 4 and a bit times lifesize. Focus stacking solved the problem in a matter of minutes. The way I do 'super macro' is to reverse a short (24mm Tokina) lens onto the nose of a Sigma 105mm macro lens. In our sample photo, adjusting the aperture to get both rings sufficiently sharp resulted in losing the soft background. So it was cold and the wasp was alive but torpid. It was winter time and I found the wasp (a queen) overwintering in the damp cellar of our house at the time. No, nothing like 40 frames each - more in the order of 5 or 6 frames perhaps. All done with the humble D70 ten or 15 years ago. How did you get them to stay sufficiently still? I assume each shot is made of 40(?) exposures?Īnd who knew that wasps faces were made from lemon skin!Īh, Jocksa, thank you. I will for sure do it manually, but i'm just wondering if there is anything for nikon, like there is for canon.
Pull the images back into your editor arrange as layers then erase the parts of those layers that are out of focus.īoth creatures were alive and unharmed by their début as photo models! NIKON AUTOMATED DSLR Motorized Focus Stacking Macro Rail Min. In essence, one photographs the subject 3 to 5 times at different 'depths' into the subject. Depth of field is then measured in fractions of a millimetre. You have to be competent at using and manipulating layers in whatever is your chosen graphics application (maybe Photoshop or Paintshop?) I'm fond of extreme macro, say 3 or 4 times lifesize. I have been focus stacking for years - ever since acquiring my D70 in 2004. Unfortunatly, the d7200/7500 don't have this feature, but i'm wondering if there are any other alternatives like for canon and the DSLR controller etc I noticed there are no focus stacking, a feature that i love on my olympus TG5 for macro shots. I'm looking into buying a new camera after being out of the game for a while and i'm leaning towards the nikon d7200/7500.
