0 Comments In this post, Hawaii photographer wraps up the 4th post in her series on manual camera settings – this one exploring Basic Daylight Exposure and Equivalent Exposure. Don’t miss other installments. Is anyone else as excited as I am about the stuff we’ve been learning about manual settings? I know that for a lot of us it’s old news and rudimentary to say the least, but to quite a few DPSers out there, this has been just what the doctor ordered. Thank you for all the email love letters! I’m SO glad the info has been helpful and that it’s starting to click!

The first thing you need to understand today is BASIC DAYLIGHT EXPOSURE (BDE). This is also referred to as the SUNNY 16 rule. Basically this is how it looks if you’re one of the remaining wackos who understand equations;): To achieve proper exposure on a bright sunny day, your ISO and your shutter speed are going to be the same when you’re aperture is set at f16. So for example if your ISO is 200 at f16 your shutter speed will be 1/200th of a second. This will ALWAYS be the same as long as it’s a bright sunny day. Atkins Physikalische Chemie Pdf Printer. Now from here, and I’m not gonna lie to you, we get to run our brains over repeatedly with a Mack truck. BUT, I promise you it will all click if you give it a second and you’ll be a superstar photographer forevermore.

So you to 100 and thus you’re going to have a shutter speed of 1/100th, because remember when using Basic Daylight Exposure (Sunny 16) ISO and shutter speed will match at f16. So you’ve got your shutter speed and your ISO matched up and you shoot your aperture on up to f16 and SNAP!

You’ve got a great, perfectly exposed beach scene. You can see mom and dad clearly in the foreground. You can also see the kids playing in the water behind them, also in clear focus. You can see the boogie boarders in the background in clear focus as well. Your image is perfectly exposed, not too bright, not too dark, JUST RIGHT! So you’re thinking you’re hot stuff until you think, “You know, there’s a lot going on in this photo. Check Ps3 Warranty Serial Number. There’s really no focal point.

It’s TOO BUSY!” You decide you’d like to focus only on mom and dad and throw everything else in the image out of focus... You’re going for a shallow depth of field. SOOOOO what’s a girl to do?... Or a boy as the case may be. Well, clearly you need to open up your aperture, right?

Open that baby up to give you a more shallow depth of field. Now we understand from the post Understanding Aperture that in order to OPEN our aperture to let in more light and cause a shallow depth of field, we’re actually going to be setting the camera on a LOWER aperture number.

This is where Equivalent Exposures come into play...

This is also the point where you really need to have read the other articles in the series.,,. For the rest of you, let’s break this down: • You had a correct exposure of the beach scene when your camera was set to ISO 100 at 1/100th of a second f16. • When you dropped the fstop down to f4, you let in WAY too much light and ended up with an image that was completely blown out. • The obvious answer would be to increase the shutter speed, right?

To let in less light? BUT, by how much? How do we know how fast our shutter speed should be? Equivalent Exposures.

Since you started at f16 and went down to f4, how many stops did you change your aperture? Look at the chart below, that you SHOULD have memorized if you did your homework from Part I... And see how many FULL STOPS you had to move to get from f16 to f4. Go on and count ’em. In the chart above you see the TRUE apertures. Those highlighted in blue are the common apertures for most lenses.
