Adjusting For Wind

[ktuli]

Its a camera, not nuclear waste, nothing to be afraid. I delete more than I keep on a regular basis. Heck, quite often I'm shooting something boring and dull and my only intention is practice and seeing what happens when I do this and that. I want all that mystery out of the way, so when I'm at something good or onto something good and you know you've only got a limited amount of time, you've got a better idea of whats going to work. I'm trying to train myself to learn to think like a camera.

This woman "gets" it! ... well done Debbie!

Meanwhile, somewhere in Vermont, a nuclear meltdown occurs because someone made the wrong settings decision on their camera. Details at 6. But first, your local weather.

If learning from books works for you, you could also go and find Bryan Peterson's Understanding Exposure.

I had a box arrive from amazon.com day before yesterday and that book was in there.

I do the same thing... but the mystery won't move out of the way. I don't think I'll ever think like a camera... not in this lifetime, anyway.

Local weather... we're under severe tornado warning through late tonight. So, if you never hear from me again... I've been blown into the Atlantic Ocean somewhere... probably floating around in the Haunted House.

Mary, fear not....once you really begin to understand the relationships in the exposure triangle the mystery will get out of the way rather quickly. It will all of a sudden all make perfect sense.

Don't forget the camera! But seriously good luck and be safe.

I hope you're right, Paul. I've been trying for several years and it just aint clickin. I think my brain's too full of other stuff.

Thanks. I'll be sure to grab the camera right after I get Lucy.

How about this for an analogy ...

Think of a bath, with a "correct exposure" being the bath filled almost to the top. The bigger the tap (or the hole that the water runs through), the less time you need to keep the water running to fill the bath; same with the camera - the bigger the hole (aperture), the less time it takes the light to "fill up the sensor" and the less time the shutter needs to remain open (ie "higher shutterspeed).

For ISO, just think of that as being like the pressure of the water - if the water supply to the tap is connected to a high pressure boost pump then the water will flow in faster - so you have the option of not letting it flow as long, or having it flow through a smaller hole (tap). (so for a given time the tap is open - and for a given size hole - the bath will fill quicker if the water comes from a higher-pressure source.

Make sense?

So, if I increase the ISO, then I can adjust the aperture and/or shutter speed to achieve essentially the same end result?

Yes. In reality though, ISO is a different one to explain in terms of baths -- it sorta/kinda changes the size of the bath - so the higher the ISO - the "smaller the bath" (or the less water/light you need to fill things up). Perhaps think of ISO as a "light multiplier" or "light boost setting" - it just effectively just amplifies the light you give it, so you need less to get the same result.

Oh. My. Word. So I totally missed the analogy.

How about... if I have the aperture set at 1.4, the shutter speed can be relatively fast because there is a lot of light going through. If the aperture is, say at 16, then the shutter speed would need to be slower so that it is open longer to allow more time for the light to go through the lens opening?

Boosting the ISO would aid in increasing the shutter speed because I probably couldn't hold the camera still enough long enough? Or in adjusting the aperture or both?

If I still am not getting... it's okay, Colin. It's not you... it's Moi. I'll go bake some cookies that will make Martha Stewart jealous.

Perfect

Yes Or if you increase the ISO you could keep the shutterspeed the same, but use a smaller hole to get a better depth of field.

Yumm ... food!

I'm about to go get some lunch in town ... Portuguise marinated chicken (grilled), with Piri Piri sauce (fire extinguisher on stand-by) - cheese - and fries (I blame Mary!)

After working so hard to explain something in language I can grasp... you earned it! Get yourself an ice cream for dessert. Thank you, Colin... really... a lot.

Funny you should mention that! They also have cheesecakes

Nah - too easy

I sort of feel like I'm having this conversation with my 18 yr old... laughing hysterically because I am clueless... see, told you... I am clueless.

This image is one of the better ones... I think. The wind was blowing a lot and since I had no clue, really as to what the outcome would be... what do you think? This was Manual Mode, F/2.8, 1/4000s, Center-Weighted, ISO 200

Nothing wrong with that young lady: might you have tried f4 it would look a bit darker but then you could use ACR to get the leaves back. I use the guess method; that is I work it all out on a scrap of paper, then throw it away and shoot, look, and shoot again.

[Peter Ryan]

Well done Mary, I can see you mind getting around this now. Just take your time, enjoy learning and come back with any further questions.

[ilovelucydog]

Well, then I hope you got yourself a piece of cheesecake. Send me the bill... the Haunted House on 42nd street just off of Atlantic Ave. The one with the Labradoodle.

Thank you, Steve. I shoot, delete, shoot, delete and repeat... save an image or two and start again.
