HI,
Here's my situation. I would like to try some portraits of our 6 mo old with my 4x5 view camera. I only have a readyload holder and use TMX100.

With available light for headshots I'm at 2 sec exposures and theres no way he'll stay still for that long. So my question is:

Can I push the TMX100 2 stops to 400 with acceptable results?

Has anyone tried this? Are there any examples on the web that I can see?

I have searched and can find nothing.

Thanks for your expertise!

Mike

May I ask why you would want to use 4x5 for a child's portrait? I remember when my daughter was ^mo, there was no way to keep her still while taking photos. I used the 35mm w/ motor drive and shot several rolls in order to get a couple "keepers"

Huntsville,
What is the available light situation that forces you to shoot at 2 seconds? If you got next to a window with a good amount of light coming in, I'd think you would be able to get at least F5.6 at 1/60 at ISO 100.

As to pushing film, I've never done it and don't understand why so many people go in that direction. It's an easy way to get ugly highlights and poor shadow detail. I almost always pull film and reduce development, but that's just me.

How about flash? You can do amazing things with flash by getting creative with lighting controls. I've got a cheap piece of translucent white fabric from a fabric shop. Stretch it between the subject and the flash and with a little practice, you can approximate a softbox. Throw in a junk store flash on a $15.00 slave and you've got backlight. I use a (gulp!) digital camera for lighting tests.

Doug,
I guess I should have said my cheap homemade lighting system in the basement!

1-90w flood w/ homemade diffuser as main light
1-4'x4' matboard reflector
1-250 halogen aimed at white background(bedsheet)

also, with a 210mm f6.3 lens at 4ft from subject DOF would be miniscule if I shot wide open. I was thinking in the f22 range which would give me approx 3-4 inches DOF.

I took some polaroids of myself last night and was somewhat pleased with the results. Not with the subject(me), but the lighting.

I'll try to scan and post a pic later.

It got me thinking that maybe I'd try it with a more pleasing subject. The little guy!



Mike

p.s. My wife is still recovering from the surprise 4x5 purchase. Adequate studio lighting will have to wait until the dust settles!

Brian,

I like the look of those Alien Bee lights. Do you use them? If so, is the quality decent?


Mike,

My "studio lighting" consists of a Vivitar 285, an umbrella, and a thrift store flash on a slave. I can't get fancy, but I can have some fun. Around $150.00 is all, but if you just surprised your wife with a 4x5, then........

I still think natural light might be the way to go. 90 watts may not be enough firepower.[/img]

I have White Lightning's, they're made by the same company. I find the color temp a little cold, but nothing an 812 filter on the lens can't cure.
