Have some observations regarding noise, exposure and image quality that wanted to pass along. We always talk about exposing to the right, noise creeps with under exposure etc.
Had a chance to shoot a couple of rodeos and I'm amazed at results. For the first we had the exposure sort of OK but not pushed all the way to the right, as you go more to the right yo loose shutter speed and when shooting action gets your attention. ISO was only 1600 ... results were salvageable but not good. Images needed lots of work be usable and quality was not there. Last night we went up to 3200 but made sure it was all the way to the right with a few blinkies showing on extreme whites (not many) and results were excellent, good IQ.
Not posting the images here since we like to keep all nature related but can see a couple in Friends and Family. Fabs slow pan was taken a low ISO but the other at 3200. Will be posting more in the next few days so you might want to take a look.
With birds in the field is a little tougher with harsh light but it applies the same. Might want to try under exposing one on purpose, take two or three with one being perfect. Difference will be day and night !!! We talk a lot about noise might be a good idea to experiment and see for yourself !!
