Pixely


 
 
I've changed my file size to see if that would help get rid of the pixel look in my outside horse shots. Do I need to do something different?

  Why shoot at the highest iso?

  I thought if your subject was moving at a high rate of speed that you needed to shoot with a high iso, Is that wrong? What should I shoot at?

  High shutter speed. High iso if needed to get a high shutter speed.
But not the highest iso the camera will go up to during high noon.

  So f/8 or f/11 with the lowest iso that the camera will allow with those shutter speeds? Or like an iso of 400? Thanks for being so patient with me.ww

  There is also the Sunny 16 rule for bright sunlight days set your aperture to f/16 - but this is just a guide and if it doesn't allow for a fast enough shutter speed or you want a shallower DOF, use a bigger aperture. Another rule of thumb is that most lenses are sharpest about 2 stops above its fastest stop.
You should be able to set for f/11 or f/16 at ISO100 and still have a fast enough shutter speed for the capture you posted but you have to check your meter to be sure.
Have fun Wendy

  Iso 100 with f/16 is going to give you 125th of a second shutter speed, so for you, you'd need to open up to f/5.6 to be around 1000th of a second.
Iso 200 is a good safe way to go.

  Wendy, with your camera, well lit outdoors shots will be practically noise free at ISO 400. If you intend to crop in a great deal, you may start to see a little noise closer to 100%but for lesser crops, not really. If that is the case (the need to crop in because of the distance to the subject) then 200 is a good choice. At the distance it looks your subject is, you're going to get a decent DOF with something like f/8. Even down to f/5.6 unless you're zoomed all the way out and that will then be at the fastest for the lens and probably not the sharpest. It's rare for me to shoot anything at a smaller aperture than f/11. Most are at f/8 or greater.

  One more brief comment after looking at the picture again. If you use a larger lens opening, say f/5.6 for example, you will keep the horse and rider in sharp focus and blur out somewhat the background which will add more of a sense of depth and make the main subject stand out more. This too will allow you to use the lower ISO setting and retain a higher shutter speed to freeze the action.
