So I need help figureing out what to set the shutter speed to for a good picture of a horse galloping, I really want some good action shots but I need to up my shutter speed, 80 is my lowest iso setting and 1600 is my highest, which is better?
I used iso setting at 400 and got these (taken at the last rideout) They're not as crisp as I would of liked them, however i'm still trying to figure my camera out.
I found this link if anyone like me wanted to understand it better. http://www.brighthub.com/multimedia/...les/72927.aspx
So what I am understanding from the article is low iso for pictures with natural light. But a low iso wont capture moving objects. And a high iso for indoor or low light, and it captures moving objects. I'm going to have to play around with this. Lol
It really depends on what it is you are shooting, how fast your target is, if you are shaking, if your camera has a stabilizer, the amount of life, the lens. So many things factor into this question.
What I recommend you do, is take your own camera out and try it in different settings and see what works. If you go into the horse pictures area, you can take a look at some of the shots I've taken at different paces. Not a single one of those photos was taken with the same setting as the previous picture.
ISO is not the same as shutter speed. ISO on a digital camera is effectively how much the sensor amplifies the signal. The higher the ISO then the less time the sensor needs to be correctly exposed. However as with any form of amplification, it creates noise. In digital cameras that is colour noise.
So the lower the ISO the better quality the image. The higher you go the lower the quality will become - it wil look softer and you will start to see noise. Its all relative however. On pictures used for the web etc you wont tell the difference. If you print and blow up the photos however, or look at a high res screen then you will.
So for any exposure, if you increase the ISO then assuming you keep the aperture the same, then the shutter speed can also increase.
Usually you will have an auto-iso setting. At first I would simply use that and focus on controlling your shutter speed and aperture for the shot you want. Worry about iso last.
