How your Exposure will effect the Colour of your Photos..

posted on 16th of october, 2009

For some people on here, this will be very basic info, but for others, i hope it will help you create vivid, better then life images! There are so many techniques on the camera itself that can be used to create different and interesting photos.


Exposure is one of the things that will definitely effect the way the colors in the photograph come out.

Exposure is all about how much light is allowed to fall on the photographic medium, be that a photographic film or an image sensor, during the process of taking a photograph.

Correct expoure is determined by the sensitivity of the medium used. In photography, this sensitivity is measured on a scale published by the International Organization of Standardization (ISO). Exposure is a combination of the length of time and level of light received by the photosensitive medium. The camera lets me decide both of these by adjusting the shutter speed and the aperture. Slower shutter speeds (exposing the camera sensor for longer) and greater lens apertures (admitting more light) produce greater exposures.

If there is too much light let into the sensor, be that due to too large an aperture or too slow shutter speed, the photo will be over exposed, too bright and not contain any detail. These areas where information is lost due to extreme brightness are described as having ‘blown out highlights’ or ‘flared highlights.’ If there is not enough light, it will be underexposed, dark and washed out. These areas where the information is lost due to extreme darkness are called ‘crushed blacks.’

It is often possible to digitally correct an image that is incorrectly exposed, but if the image it too bright or too dark, and the detail is not in the photo, you can never recover it. It is also difficult to get good contrast in poorly exposed photos.

Then again, the photographer may be going for this exact effect. This is also when photography becomes subjective!

There are 3 main things on any digital SLR camera that will effect the exposure. These are the shutter speed, aperture and ISO. In my next blog, i'll explain these, and how they will effect and alter your images.

I think my digital camera (not a DSLR) only allows me to adjust iso and not shutter speed and aperature. I wish it did, though!

Usually I reduce 1/3 EV when I need a saturated color, such as shot on blue sky, yellow trees and so on. NIice article~ My friend!

yes, very informative article Rebecca. congrats.
UE or OE is the bane of all stock photographers or any photographer who wants to get a good shot. you can rescue a poorly exposed image, but you will have to fight very hard to get rid of noise and all those terrible things that will surely make no friend of you to any reviewer , lol.
i also find that the time consumed by this rescue job is so much better spent in a reshoot. of course , at times it's not possible to do that.
lovely to see you here !

hey Creativei, in regard to your question to my blog, i would not say your teacher is wrong, but if you are in a dark environment, and you dont increase your ISO, the camera will give you a slow shuttter speed, so as to let in as much light as possible. This is fine if you have a tripod and the subject is staying still, but if you dont have a tripod, and the subject is moving, you may need to increase your ISO. I would rather capture the moment, and have the image a little grainy, then blurry!! Its just good to know how the ISO will effect your images, because you will need to use it sometime!

looking forward for your next article, thanks for the share. Well my photograph teacher told me to keep the iso in auto mode and play with aperture and shutter speed, is my teacher wrong????

I was reading something today that said something about "exposing" a certain part within the subject, and going "huh?", then came your post--unraveled the jargon that just didn't click in my head at the moment. Thanks!

I look forward to your next blog.
