LF Polaroid Film Question - simple...

On 4x5 Polaroid film, the ASA-100 product... Just curious about exposure and development times.

Does more exposure make the colors darker or lighter?

Does more development time make the colors darker or lighter?

I'd experiment and figure it out myself, but at about $5/sheet I'd really like to minimize the ones I throw away in the name of tinkering...

Thanks..!

More exposure makes you Polaroid over-exposed. Lighter.

More development time is seconds or minutes? I find as long as you develop for the minimum time for the ambient temperture, you're fine. Over-development by a little bit doesn't much matter. I've never developed minutes past the suggested development time, except for expired T-55 to avoid chemical solarization.
