Aperture to Shutter Speed Table?

and as long as histogram is in the middle im good yeah?

left is under right is over? i want somewhere inbetween?

obv unless im purposely trying to under or over ..
 
Danny. I found for me that the best way of getting all this info straight in your mind is to look at one aspect, say aperture, then work in Av. Take pictures at say f1.4, f2.8, f8, f11 and f22 ISO on Auto.. choose something to take pictures of. Take them then look at how your change of aperture affects dof and look at how the camera has adjusted the ISO and speed.
Then look at using Tv and do a similar test. May be take a picture of something moving. Newton balls someone cycling, a ball bouncing etc and see how by changing the speed will either freeze the motion or give the required amount of blur. Remember a sports car will need a faster speed to capture sufficient blur to a push bike.
Read the manual...not necessarily all at once. Bite size bits. Then play and observe.
I'm also new to this, but reading the books. Buying the mags. Looking on youtube for info, and of course asking on here ....don't forget to look through all those OLD post too is all part of gaining a better understanding of a very interesting subject!!
...learning is fun!! Experiment and look at how it affects your picture

yes i know 200 is too slow lol thats what ive just been standing up doing .. wacking the speed up to atleast 1/50 and then adjusting the ISO to compensate :)


so if i want portraits your saying turn the lights off so its pitch black and just use flash lol!?

No. Leave the room lights on.
If you set the camera to ISO100, f8 and 1/125th take a shot in the room - what do you get? It should be black (nothing) - None of the ambient light is recorded (day or night if you are in a small room - unless the sun is shining through the window) If the sun is streaming through the window, close the curtains/blinds

Now get the flash and stick it on the camera and bounce it up into the ceiling. Take a shot in ETTL. - Ignore the meter for the moment.

Should look nice.

You need to get the flash off the camera and add the second flash but do you see what I mean? You can also increase the ISO slightly as that will reduce the power your flash needs to take the shot which will also help batteries and recycle times.

no probs Danny....we have history lol.... that why i never mentioned flash until now:thumbs:

There is no correct Histogram shape as such as it is representing the tonal range/values in the image.

Generally, to the left is underexposed and 'ettr' exposure to the right is over. However this depends on the scene so try not fix and ideal shape in your head, you need to make the call really based on what you see and your experience.

It depends on the scene. You generally don't want the graph clipping the right or left sides however when using black/white backgrounds then that will happen.... You just need to understand why.
