Harriet's incredible series of water drops inspired me to get out my seldom-used (maybe even never) extension tubes and see what I could come up with. These are with the Tamron 28-75 f/2.8 macro with 12mm and 20mm stacked extension tubes. Each is with flash moved off the camera with a bracket. Neither is close to the quality of hers, but I like the shadow on the first.






I used the same set-up for a series of shots of a couple of iris buds that are getting ready to open.





Unabashedly imitating in an attempt to get better,

Paul

Not bad at all for a first try, Paul.
I love the last one, really nice rich color!
You realize going up against Harriet is like getting in the ring with Rocky, right?:G

Like GW said. Not bad for a first attempt. Those are going to be beautiful iris once they open.

Getting there, I like your first drop picture - as you've noticed, the dof is really tiny! What type of aperture were you using? I used f16-18 but wanted to use f20 (but wasn't so sure I had enough light, even with the flash). I noticed that some of your shutter speeds were 1/60 - were you using slow speed sync? I just used the 1/180 sec for shutter speed - I think that's the regular flash sync speed? That way I don't have to worry as much about camera shake.

The iris photos are really nice, and I agree that it's going to be a beautiful flower.

Wow, I'm impressed. I've never done much macro photography, but clearly it's an entire world unto itself.

I was using about f/11 for most of the shots. Any higher than that and I had difficulty getting enough light to be able to focus. I was using the Pentax 540 flash, dialed down to 1/8 power, on Manual with all manual controls on the camera. This combo was not a deliberate choice, but the result of trial and error. Whatever combo I tried in P-TTL mode always resulted in blown-out pics. I found out enough that I want to learn more, and I'm going to continue to experiment with the macro. My next experiments are going to be with different combinations of tubes. I have 12, 20, and 38mm tubes. These shots were taken with the 12 and 20 stacked. I'll be curious to see the comparative effect of different combos.

The biggest surprise, to me, on the iris photos was the background. As you can see on the first two photos, the background was simply a solid color (dark, grey sky before a heavy rain). Particularly on the second one, it looked like I was shooting against a studio backdrop, or plugged in a grey background in Photoshop.

I'll post some pics of the irises when they open. Thanks.

Paul

I find I have better luck with the flash off-camera, but have had some success with using it in A mode and adjusting the settings on the flash (if picture is blown out, tell the flash I'm using a larger aperture or higher ISO than what I'm actually using, the opposite for dark pictures). For some reason I haven't had much luck with the flash's Ev settings - I don't understand it all enough to get it right that way.
