Photography Tip #5 26/02/2011

 

So, How are you finding the tips so far? I would like to here from you . Just leave a comment below.

 

Today’s tip is about ‘ISO’ And noise.

 

You’ll see on your camera it should say ISO on the back and there’s usually a button for it, ISO stands for ‘International Standards Organization’ and it’s a standardized industry scale for measuring sensitivity to light.

 

But all we need to know for the time being is the higher it is the more light will be allowed to hit your camera’s sensor, This is an advantage if you aren’t using a flash and in a dark area.

 

Having the ISO high can help with your shutter speed allowing you to take the picture faster, the downside is usually if its really high you’ll get more ‘Noise’ produced on your image.

 

Having the ISO low can help you keep the shutter open for a longer period to produce  blur/motion, for example during the day when its bright but you want to be able to blur the waves.

 

Noise looks like that picture you sometimes see on your TV when it isn’t tuned properly ( loads of white an black dots ), usually in colour too.

 

 

 

Professional/Amateur cameras seem to cope with the noise far better than some entry level/beginner cameras, So if your lucky enough to have a decent one you shouldn’t have to worry too much about ISO levels.

 

Although it’s annoying there are pictures around that use noise to give the image a better effect but there are  plenty of ways to reduce the noise using Photoshop or other editing programs.

 

Such as:

Noiseware

or

Topaz DeNoise

plug ins for Photoshop.

 

The camera I currently have only goes as high as 1600 but other camera’s can go up to 25600!…Yeah I need to start saving up .

 

Thats all for now, as always feel free to leave any questions at the bottom of the page .

Thanks

Dan!
