Is there a way to calculate how much light I will need?

All the new imported models can barbecue too. Maybe time for an upgrade?

I dunno, Jim. I usually do ribs in the oven. My Texan son-in-law is appalled but mine are more consistent than his 'cos my oven is more consistent than he is. And then there are stove top ribs and barbacoa. The electric fry pan comes in handy for stove top ribs. Barbacoa -- with cheek meat, naturally -- needs a stove, a skillet won't do for it.

I do shots like this with splashing water. The 1/125 of a second won’t do the job. The shutter speed actually doesn’t matter. What matters is the flash duration. Either use a good quality speedlight, I use a Minolta 5400 HS, set on 1/32 power for the shortest possible flash, or use a Profoto D2 monolight. They have a flash duration of 1/63,000 of a second, or something in that area.

You will also need a trigger. Most use a digital shutter signal, so you may need to use a slow shutter speed and connect the trigger to the light rather than the shutter. I use a Miops brand trigger, but Pluto and Vello are cheaper. They can be set to fire from a loud sharp sound or by breaking a laser beam from a laser pointer. You dial in the amount of delay from trigger to flash to get the desired photo.

BTW, here is how I have this set up. The black card is blocking the view to the Minolta 5400 flash I have on a light stand. Excuse the mess.

No problem with flash. Just use the Guide Number for your flash and place on the flash head being close to the egg. For example, with one #102 head on a 2400 Ws Black Line Speedotron the Guide number is 540. That's in feet and for 100 ISO. Place the head at 1 foot distance and you can shoot at f540 on 100 ISO film. For 50 ISO, you open up one stop to f385. For 5 stops of bellows extension you open further to f68. Plenty of light to spare, you can probably dial down to half power or less for f32 at 125th.

After a couple of pops, it should be ready to eat.
