I think I found the answer to the question, "I am new to photography and my customer has a wedding scheduled for this weekend, what camera settings should I use for..."

All meant in good humor.

This weekend? :LOL: Well they will save a lot of money and have all kinds of family fun guessing who was in this shot years later.

A much younger colleague at work who was into photography and shot with Canon must have asked me a dozen times. I finally caved, it took 6 months to prepare and I still felt no where near ready. Money shots which meant posing people, lighting, reception. Put a lot of time flash photography. Mostly because I was afraid of it because I didn't understand it. Sure I could take a flash shot but I wanted repeatability and control. You need solve any problems quickly even if you have back-up gear. There no tomorrow.

I took a few lighting courses and spent a lot of time here.


My colleague and I wound up shooting weddings together for some extra toy money but I found it far too stressful. 6-8 weddings a year just didn't give me enough time to get past the anxiety. In my trade took about 3 -5 years to get to journeyman status and you did that job every day. After two years I gave up but it was a good journey. Opened up the flash world to me. I gained a whole new respect for pros.
 
That’s all well and good, but what if you’re not on Mercury?
That's a very good question, indeed. Mercury is right there next to the sun and has almost zero atmosphere. If you were on, say, Earth, for example, you'd validate your meter reading against the Sunny 16 rule. I've never been to Mercury, but I'd assume they'd use something like Sunny 128 or maybe Sunny 256 in autumn.

I was on another site in the beginners forums. The exposure triangle came up and some members never stopped arguing that it does not exist. It was made up and people who teach it are wrong.

    Fast, sharp, and lightweight! A great lens
    This is my main workhorse of a lens and I love it. It's very light weight (only around 2.3 lbs) lens. I've been able to hand-hold it for an event...
