Just curious. When using manual mode do you just set the exposure until the cameras metering tells you that you are right or do you just guess it yourself?
This is my ikle guide to manual exposure with a very important bit
If you look up grey card on google you will see that there are more exact ways to do this.. but they dont work if for example your on a long lens.. unless you have extrodinary long arms
Point towards the scene your going to shoot or somewhere near that has the same light as the scene your going to shoot.. look for somehting similar to a grey colour.. for example shooting sport i look for a light bit of grass on the pitch..
Point your camera at that.. I find spot metering is best for manual exposure.. using anything else then you need to fill the frame with the colour
note the settings when the exposure is showing spot on.. dial those in so you have the exact exposure.
now point at anything you want and your exposure will stay the same
IMPORTANT : this may seem like a no brainer to some but it slowed me down at first... now while you are in manual .. IGNORE the exposure meter telling you that you are under or over exposed... thats the camera guessing what your exposure should be.... ignore it.. your choosing the exposure... keep chimping (checking your histogram and actual picture to make sure exposure is staying as you Want it ie maybe light changes)
WHY?
Well again let me use football as an example.. a night match .. i do as above and set the exposure for the grass and shoot away.. my exposure levels are all over the place because of floodlights or lights in the background (at non league grounds theres allsorts) and those lights tell the camera to use exposures i dont want.. theres loads more example where auto or semi auto modes wont work..
Set your own and it stays constant.. this means you either get constantly good or bad exposures
I dont use manual all the time.. on a sunny day with lots of cloud the lighting can be changing every few seconds then its AV for me... I am not stuck on manual all the time... plus my camer does such a good job I am using AV more and more.. but when needs must then its M
