Shrinking pupils. What do you use?

p.1 #1 · p.1 #1 · Shrinking pupils. What do you use?


I am thinking of getting a one of those halogen clip-on desk lamps to latch onto my C-stand when I shoot in the studio... Or maybe even some kind of flashlight since it would be more portable. I would like something that is capable of shrinking the subjects pupils in situations where there is not enough ambient light or when I would not be able to use a modeling lamp.

I'm open to suggestions. Anyone have ideas?

Why would your modelling lights not be available?

I would just accomplish it with the modeling lights, shining a flashlight on desk lamp at your subject is not going to look very professional or inspire confidence. my thoughts anyway.

I use an Einstein. If I shoot outdoors at the night, I would be forced to hook up the strobe to my Vagabond Mini power source. The instructions say not to use the modeling lamp unless plugged into an outlet.

I guess a flashlight would work, once you rig it to point at the subject. Note that battery-powered flashes do exist with modelling lights - mine is the Profoto AcuteB 600.

That is great! I didn't know such a thing was possible. I guess I know what to save up for in the future.

Do you know if any cheap LED flashlight would do? Would I require a certain power rating?

Modeling lights can quickly drain the battery on portable strobes, so your idea is a sound one. My suggestion would be a battery-powered video light on the camera.

Here's one example:

You could try turning the lights in your studio on and not shoot in the dark.

You can get a 25 watt modeling lamp for the Einstein from Buff - it's offered specifically for use with the VML.

Thanks for the input, everyone.

@BrianO: That looks pretty nice, but a tad bit pricey solution. That unit will run me $90, but I'll have to buy a battery that will run me another $75.

@cordellwillis: I actually have that item! It's kinda clunky and requires too many batteries for short durations, in my opinion. I guess I could use it in my home studio if attached to light stand. I have a PocketWizard on my camera body, so it definitely won't go on top of that.

@alohadave + @alohadave: I don't think those solutions will be too effective. I heard that sometimes modeling lamps will need to be pushed to high power in order to get effective results, so I definitely need a stronger light source.

I guess a flashlight will be the most cost-effective solution.

Not the modeling lights, the ambient room lights. Your flashes are more than powerful enough to overpower the ambient unless you have a reason to shoot longer exposures.

Can you power that video light with AC?

Morphine usually does it for me.

Hmmmm. You are correct. I tried this out last night with my very bright studio video lights. The strobe did indeed overpower the very bright ambient light.

just take two shots; the first one will close their pupils down.

Do pupils stay closed for long? Would shooting in 4-second intervals work you think?

might be too long unless they're on drugs. lol
usually i fire rounds of 2-3 shots within a 2sec interval.

take a look at your own eyes in a mirror to see how fast they contract, it's fairly quick.

If you have a trained model, you can tell them to glance at a point of light before they look at the camera.


I'm assuming you're outdoors; indoors use ambient lights!

I would place a low cost LED video light on a stand. Fits on the same as a strobe or speed light. Looks professional, has adjustable light output and can be used alone for a different look without flash. It would also help with focus in really dark conditions. Around $35.00 on Amazon.
