Holding filter in front of lens?

[hipsterdufus]

Okay, so I have a fairly dumb question, but first, let me give the background story. I would like to do a project utilizing multiple exposures. The only camera that I have that can do this easily is my trusty old Argus C3. However, I want to utilize the September skies in Michigan and make them very dramatic (this is in black & white, btw).

Back to the question: as we all know, in order to do this, I need to use a red filter. I've got a 52mm red filter (25). Would it hurt just to hold this filter in front of the lens on the Argus to create this effect? The opening for the cintar lens is only 19mm, so it should easily cover this lens. Will it distort the image in any noticeable way? I'd prefer not to spend the money to order the rare 19mm filter and then wait for it to arrive. Your thoughts? Thanks a lot.

It will be OK if you make sure there are no reflections off the back of the filter

Thanks for the info. I suspected that I would be okay, but I didn't want to waste my model's time by having the results turn out poorly.

Try and get everything in the shade, then the lack of a hood won't matter as much.

Personally I'd try a few catching the light too, one never knows ...

I did it sometimes when using my Rolleiflex and did not have the right size filter. It work well, only problem that in some cases three hands had been necessary !

The trick is to hold it agains the lens' rim with sufficient force to keep it from showing reflections or moving, but not so hard as to scratch it. Sounds harder than it is.

Don't forget your filter factor.

Thanks for the advice, everyone. All good things to keep in mind. Luckily, I'll be using a tripod and a cable release, so I should have an extra hand free to hold the filter. I know it's not ideal, but it's for an upcoming art show... A bit of a time crunch.
