I have finally begun to shoot again something other than family pics.
Problems:
1. Greens are washed out to almost white
2. Thin blue line surrounding white objects such as Ibis.
Have shot on aperture value and on full auto. aperture usually at 4.5 and speed of sensor set at ISO400.
Shooting with T1i and using a Phoenix 19/35 zoon with a 2x extender.
Thinking of going back to my Leica CL.....
what am i doing wrong?
Can you post an example? I'm a visual-type.
heres a pic :?

No image, only the file name.
without an image and metadata this is a quess, overexposed and serious CA issues.
ISO is sensitivity of the sensor to light.
Speed refers to how fast the shutter fires, and since your in either auto mode or aperture priotry the micro chip is choosing the shutter speed.
How your pointing the lens at the subject matter will influence the meter which recommends to the chip what speed to apply . An aperture of 4.5 in bright sun light may be the issue, as you will need a very fast shutter speed for a correct exposure and you may have run out of options.
Sorry to be so ignorant but what is CA?
thanks

No need to be sorry.
CA stands for chromatic aberration. It's when all the colors fail to focus at the same point. It is seen as a fringe of color near where light areas meets dark areas.
Sorry, i should have explained the term.
That explains the blue line around the white bird. The bird was standing in front of a dark background.
I think the washed out green is a matter of lens aperture and speed. I am going to use a polarizing filter and see what happens.
Sensors are really different from film.
Thanks for all the help.
The polarizer will cut the exposure a stop or two, but that may not be the best overall solution. Be sure to look at the metering mode you are using. I don't know Canon's terminology but you should have at least three modes: spot meter (a small area is metered), center-weighted (a larger area in the center is metered) and an overall metering mode - Nikon calls it "matrix."
canon uses evaluative.
Be sure to rotate the PL for the best results.
Try to set camera to "default" settings. Pull out the manual and check "toubleshooting". Good luck!
