hello

What we're attempting to accomplish may not be possible without purchasing a light meter--instead, we downloaded a 'sunny 16' paper slide calculator:

There is an interior shot, 'mood lighting' in restaurant, 4x5 HP+ film...

Please take a moment to help set the f/stop and speed, no flash...first time using the chart, and not certain on the correct reading...somewhere on the chart (at the 'EV' column), it reads, 'Average home, night interior,' EV5.

When we bring the ISO row--ISO 400--to the line up with the EV5, it gives several possibilities for f stop and speed: 1.4/60, 2/30, 2.8/15, 4/8 and 5.8/4.

We'd just choose one (depending upon other concerns, like depth of field, etc.) and release shutter? It's that easy, or do we really need a light meter for this?

thank you

ps: if we wanted to add a Yongnuo yn568ex flash--using manual settings, would the 'sunny 16' chart be unable to assist at that point?
