time marches on...

Playing with macro. The setup: 50mm f/1.7 lens mounted on a reversing ring. That connected to a 2x doubler/extension tube combo & that whole mess mounted on the camera.

First shot is actually a 30 second exposure. The watch is laying under a small table lamp (approximately 10 inches away) with a 60 watt bulb in it. First attempt was with the lamp off. I was trying to get just the glowing hands, but it just wasn't enough light. So, I did it a second time and flipped the light switch on for approximately 1 second during the 30 second exposure. That's how I got the second hand frozen on a long exposure.

This shot is with the lamp on and is a 3 second exposure, hence the multiple second hands. I need to go back to the RAW file and darken this one up some I think.

Both shots taken from about 5 inches away @ 45° angle from the watch face. Focus point was the word LTD. This was mostly a DOF exercise (f/16), but turned out kinda cool.

I think you need a bigger dof to be honest. But with this kind of magnification dofs are tiny. If you can get a polarizer on your set up give it a go. It'll get rid of any glare on the glass.
I've been doing reversed lens today as well. I had to use blue tack to hold my lens on though. I haven't got an adaptor for this camera yet. Magnification was 42+. :shock:
I'll post a picture. It's a bit crappy though.

The DOF here is as good as it gets with this setup.

Shooting closer to square would give more, but this was mostly to see what kind of DOF I can get with this lens arrangement.

I need to pick up a different 50mm with a smaller aperture to mess with.

Here's one I did today, a 34 second exposure in ambient light from the window 10 feet away. Strobed the lamp like a flash- on & off as quickly as I could flip the switch, which highlighted the second hand.

Interesting stuff Jim!
I hope that's not the time you get up in the morning because it's too early for your sunrises. :lol:

Hey, Jim, I really like the first one the best. Love that dark background with the yellow and purple - it all works beautifully. DOF doesn't bother me a bit here, I like it.
