I went back today the my friends garden where all the butterflies are. I have no idea how my camera ended up with the ISO at 1600. I took lots of photos in manual mode without checking the ISO. I assumed it was at 100 like it was Saturday when I took the other butterfly photos. Anyway, whether it was the ISO change ot the fact my hands were not as shaking the second time around, I think the photos turned out mcuh better. The flowers are fading and the butterflies are on their last wing, literally. They are elderly. They are mating right now and will soon die. I would love some tips on how to improve both these photos as well as what to do next time to take them better in the first place. I would also love to know what made the differance because I htough ISO being higher would create grainy photos. Does that mean these would have been much better with a lower ISO?

you only need the id number between the thumb tags

too slow - you figured it out

edit: The images are very clean for ISO 1600. Lower ISO would have been smoother, however you would have had a slower shutter speed and possible motion blur or camera shake.

Higher iso got you that super high shutter speed which helps the images look crisp. At the same time it added the grainy noise you can see in the background. However, that's not a lot of noise to deal with because it looks like your exposures were pretty good and you didn't have to boost the levels in processing (which ends up bringing up even more noise). If you own neatimage or some other noise reduction software, you could eliminate that minimal amount of noise if it bothers you. It doesn't bother me. Some of it would also go away just by not saturating the colors so much.

edit: I see you are getting some mileage out of that 50mm! You should get your hands on the 85mm 1.8 next. Primes are da sh*t.

Nice shots at 1600. Mine would have been grain city!

I do hate the end of summer though... :-(

85mm huh? I was thinking I wanted a micro lens. But since I do most try to take photos of kids, I should probably get the 85. I have heard it is awesome for portraits.

Thanks for the explanation of the ISO. Now I understand why it let me get the shutter speed higher than it did on Saturday. That makes sense!

High ISO grain is only noticeable in the dark. Kinda a catch 22. I shoot often at 1600 during sunlight to get high shutter benefits, and the noise rarely shows. Other people should take note if they haven't tried this already. I would rant about how ISO is not the cause of noise, but that's been discussed already. Nice shots!

Whew! I actually like the high ISO and HUGE STRONG colors. Very vivid and enjoyable. Gives it a dramatic look. Thanks for sharing!
