Question About T4i And Noise

Hello,

I have had my T4i for a few weeks now, but I've been noticing what appears to be noise at 100%. I have been taking most of my picures indoors with flash and shoot raw, but today I compared those with my XTi pics and i notice noise in the T4i pics.

T4i pics were taken indoors with flash at ISO 200 in raw.

XTi pics were taken outdoors with flash at ISO 200, but in JPEG.

I'm not sure if shooting in raw has anything to do with it.

Thank you for any input!!!

Shooting in RAW has nothing to do with it. The amount of available light is typically the culprit. Unfortunately, your example is kind of an apples to oranges comparison. Still, if you have some example photos you can share I am sure you'll get plenty of feedback.

Remember that your new cameras images at 100% are nearly twice as magnified as your old cameras. Up scale your old images to the same size and see what that dose to the image quality. If you were to print the images at the same size, say 10×8" you will that the new camera is much better then the old one. Even at 36×24" for each print the new camera will be much better than the old. you would not compare prints of images from the old camera at 10×8" to prints from the new camera at 20×16" and expect the same quality. That is exactly what you are doing when comparing the images at 100% on the screen.

How would I up scale my old images?

Thank you for your rsponses!!!

Can anyone tell me how to upscale my XTi images to be similar to the T4i? I'm using Photoshop CS6.

Thank you!!!

Ctrl-i then change the long side to 5184, if that is the resolution of the rebel.
