Help with yellow filter and flash on Yashica GSN

[juggler]

Am I doing it right?

I have a Yasica GSN. I use a yellow K2 filter (filter factor 2 = 1 stop) on the lens.
With ASA 400 b/w film I need to set ASA 200 on the camera, right? Since the metering for the Yashica is independent.

Now if I use the camera indoors (in flash mode default 1/30s) with a Metz 32 MZ-3 flash that comes with auto-sensor, I need to set ASA 200 on the flash as well right? The flash aperture will correspond to my camera aperture.

Incidentally, does it matter in the resulting picture if we use yellow filter indoors?

Thanks!

I can't help you with the flash calculation at the moment, I fell into my Jack Daniels and Coke and my math skills flew away. But I can tell you about filters. Yellow filter lightens yellow and darkens the opposite (complement) of yellow, which is blue. That means blues in the scene will tend to go dark(er), yellows will tend to go white(er). I suppose if you had a lot of incandescent light (tungsten) which tends towards yellow, the filter might help with that, but since you're using flash, perhaps not so much. Frankly, and I am not Frank, I would not use a color filter with B&W film and a flash indoors. But that's just me. I'm funny that way.

Good luck with the math, I'd help but I'm being pummeled by plus signs.

Let's simplify this: for the Yashica GSN, yes, set it to ISO 200.

Aha! You've fallen for one of the oldest tricks in the book! The first, of course, is never get involved in a land war in southeast asia, but the second, only slightly-less well known, is never go in against a Sicilian when death is on the line! Oh wait, that's something else. Never mind.

I know, it was hey - what if the battery requires the ISO to be set wonky anyway, on account of the mercury battery debacle? Or is it spring ahead and fall back? I'm all hung up on the knob. It's 11:20 and time for the penguin on top of your television set to explode.

For indoor flash remove the filter and set flash and camera to 400 speed.

Sounds like that soup you had is pretty powerful stuff, Bill! lol

I love that movie.

Ever heard of Plato, Aristotle, Socrates?

Yes, you're right!

Yes, you're right!

Hey, Juggler,
Yes, your changes to the flash are correct. As said above though, the yellow filter will probably do nothing for you indoors. If you are doing portraits though, a green filter might be in order. Many of the old camera/photography books recommended a green filter as it enhanced the eyes and lips, and tended to reduce skin blemishes.
Just my thoughts. 😎
