what is the difference between ISO speed and exposure compenstion in digital camers?

Answer 1

Increasing the ISO makes the camera more sensitive to light, so you can keep on shooting indoors & during dusk without the flash. The flip side is the higher ISO levels also degrade image quality.
The EV setting forces the camera to overexpose (+EV) or underexpose (-EV) a picture. Sometimes you want to do that for creative effect and sometimes - with tricky lighting conditions - you change the EV setting because you can outsmart the camera.

Answer 2

the various distinction is shutter % is how briskly the shutter opens to allow mild into our digital camera, no matter if its an SLR or a P&S, onto your sensor. The longer the shutter is open (ex. 3' stands for 3 secs, a million/25 stands for a million/4 of a 2d) the further mild is enable in onto the sensor. vast Day mild and different nicely mild parts do no longer require slow shutter %, attempt to keep it as quick as you could to capture a second. The extra improve you develop into you could upload consequences with the help of increasing or lowering shutter %. Low mild circumstances require slow shutter speeds like a million'. This although may reason digital camera shake or problem can flow. ISO is a way that you'll be able to keep your shutter % truly quick yet mutually it really is going to create "noise" on your imagine. some cameras cope with ISO extra effective than others. ISO develop the sensitivy and make imagines extra brighter. it really is massive in case you do not pick digital camera shake which makes imagines blurry because you may have the shutter % at a higher % than in case you probably did no longer have ISO grew to develop into up extreme. i am going to commence out with shutter %, contained in the daylight or outside and its stunning and sunny, have your shutter % quite quick in case you pick to capture a second (a million/2000). some nature photographers make the shutter % slow to create "life" in an imagine, alongside with making a river white capped or water falls seem lengthy and white. because it really is going to develop into cloudly, you could favor to decelerate your shutter % in holding with how a lot mild there is. evening photographs you want quite slow shutter % to capture the mild. ISO is a way out of turning down your shutter %. In vast day mild you should keep the ISO to a its lowest putting. This creates the smallest quantity of noise contained in the photo. because it really is going to develop into cloudly and also you do not pick to sacrifice shutter % and picture blur take position your ISO element to 400-800 in holding with the way it seems. In low mild interior you likely might want to turn your ISO settings to its optimal so that you do not sacrifice shutter % no matter if that is nessicary (ex. events recreation like basketball). you should apply a flash in case you do have one. An exterior flash per chance favor for SLRs once you've one because it provides a extra effective coverage than the bulit in flashes. desire that enables! question me any questions and that i'd be happy to help

Answer 3

ISO were a film speeds at 100,200,400,800,1600 and exposure were stand for Apertures for controlling different lightings,like f/2.8,f/3.5,f/4.5,etc.

Answer 4

higher iso can cause graininess
ev will increase the light without graininess
