3x Life-Size Refraction Photos
Jan 20, 2013 10:58:39 #
Went out this morning and played in the dew soaked grass. Had a little fun with the 60mm reverse-stacked on the 100mm. Had it cranked all the way out so I'm guessing 3x magnification. I would do the math be to lazy this morning. Not happy with my insect photos yet but these are OK. I find it is Possible to get both the dew drop and diffraction both in focus but extremely difficult. Lots has to take place. The drops are better if circular in shape , the subject behind must be Squared up to the drops and the drops must be in a Perfect straight line and of coarse you must be squared to the dew drops. If not perfectly straight, then the refracted image take on different stages of sharpness. All of these were shot at ISO320 1/200-sec at f/22, and I had to crank-up the speedlight.
All taken while laying in the grass, single shots, hand-held. This is were a studio set up would benefit getting everything perfect before the shot.

Very nice! I'm impressed.
I tried with full extension tubes and I just couldn't nail the focus. I tried live view and zooming and just couldn't see well enough. I racked focus, tried multiple shots thinking at least one would be there. Zero.

Thanks, It's a start. I just came back from photographing orchids in the same manner, and have learned that the more flat the subject, the better the focus. DOF inside of the water drop is an issue also. Here's an example of a very deep orchid flower.Very nice! I'm impressed. I tried with full extension tubes and I just couldn't nail the focus.

Damn! I was hoping that my problem was in my choice of orchids for the refracted image. They are difficult in and of themselves because of their "non-flatness". So I was going to change to something with more patterned petals....

The other issue I'm having is the excessive reflections in my drop from my lighting source.

Phalaenopsis orchid flowers are pretty flat and the most common, give them a try if you can find some in flower. I'm trying all this out in the field. If in studio I would try moving the flower back and worth and see if that helps. Further back might flatten out the refraction. As you can see in the first photos posted you can see the flash from my softbox, the dew drops were on top of the blade of grass. Subtle but still there. In the orchid post the water drops were Under the leaf so the flash was blocked from the water drop. I just turned the photo over to post.Damn!

These are outstanding, I am jealous of both your dew and your flowers... guess that I am going to have to stop posting lazy shots here, like I said you are going to be a monster with that lens.

Adding a little glycerin to the water will allow "dew drops" to stay spherical as they get larger.

Not sure how to add that to the dew. In this attempt the only set up was placing the flower. i had to find the right piece of grass, laying the right distance from the ground, dew drops and the whole nine yards. If I were to stage I would use sugar drops I think. I've got some good ideals but working all this week and have little light when I get off work. Thank goodness for the weekends. I did use a mist bottle for the orchid shot. Wouldn't know where to find the glycerinAdding a little glycerin to the water will allow "dew drops" to stay spherical as they get larger.

Thanks, Yeah, got to try the 60 reversed onto the 100mm. I guess this is around 3 times mag. as I was focused to the max. Have to tell you I'm missing my spiders, but will play with this for awhile. Did get a few bugs this morning before the dew shots, but not happy with my DOFThese are outstanding, I am jealous of both your dew and your flowers... guess that I am going to have to stop posting lazy shots here, like I said you are going to be a monster with that lens.

Vegetable Glycerin is available in some "health stores" and is used as a natural skin care product. It is sweet so could probably be used to feed flying insects while you snap away.Not sure how to add that to the dew. I did use a mist bottle for the orchid shot.

Martin, your really getting into these reversed lenses, it's going to be hard for a lot of people to keep up with you and that includes me, I think your doing a great job! keep at it.

Just having fun Roger. I hope everyone comes out and plays. I have to say this is more difficult than just using the 100mm, but only had a few days to play. When a few of these guys with studios get it all figured out I'll be left in the dust.

Those are cool! Nice work fstop22 (is that a play on "catch 22"? :) ) :thumbup: :thumbup:
