The megapixels question is something that gets ever more confusing, especially when you have new cameras coming out at both ends of the extreme! Sony has the 12 megapixel full frame sensor A7s camera, and Canon just released the 50 megapixel monster 5Ds!
In addition to talking about Megapixels, we’ve got questions on night time photography, and we talk about exposure lock when using the focus and recompose method of shooting.
Here are all the questions answered this week:
napaskaters:
“Spyros how do we do nighttime star photography.”
Christopher Sears:
“Do you think that John Reznik meant to ask about locking exposure instead of locking aperture? Locking exposure would make more sense with the first part about back button focusing.”
John Reznik’s original question:
I’m shooting with a Nikon D7000 and using the AEl and AEf for BBF. How do I lock the aperture when in spot meter mode?
Maryanne was asking about megapixels and resolution in trying to determine what camera to buy and says:
– So the first specification was effective megapixels some have 24.2 and some have 18 what does it mean and which one is better?
– The next specification I have a question about is resolution. The one I am looking at says 6016 x 4000 is that the standard and is that good?

Lightroom is a powerful photography tool, but the problem with powerful tools is they’re often complicated and intimidating, but it doesn’t have to be that way.
