Shadows and Reflections on my photos :(

if you're using pop up flash, you'll get more shadows doing a portrait shot than a landscape shot just due to the position of the flash bulb and the angle the shadows are cast.

need to replace red convergence integral circuit ic.

Set up a cleaning session on the sensor frrom settings and see if that improves it

you need video to windows movie maker converter

Are you using the software to do the download? Or did you take the card out and use a card reader. If you used a card reader, sometimes you have to re-format the card in the camera via the menu before you use it again. Hope this helps.

No, you can reduce the saturation but not go mono, (in the parameters settings)
You will need to adjust the colour balance and convert to mono in photoshop (or similar)
There are quite a few articles on the web regarding shooting in IR with the rebel, best results can be obtained with a modification to the camera http://ghonis2.ho8.com/rebelmod.html (reversable by using a IR cut filter for non IR shots) as it contains quite a strong IR filter which means although it is possibler without modification exposures will be quite long with IR filters and focusing difficult as the auto wont work and you will be able to see very little trough the viewfinder once the IR filter is on.
Here are a few articles, they may not relate to your exact model but all the eos cameras are somewhat similar.

Im sure there are many others.

Best of luck

try to change the mode in which you are taking the photos

the light is a flash and not meant for constant lighting. night shot is an inhanced mode for low light condition and has nothing to do with the flash

Shadows, especially circular shadows, are pretty common with the pop-up flash. What you are seeing is actually the shadow cast by the end of the lens. This happens especially on wider angle shots.

The solution is to find a way to get the lens out of the way of the flash. You can get an external flash, like a 430ex or 580ex, which elevates the flash far above the lens. That is an expensive option so first you might try making a diffuser for your pop up flash, which softens the source of light and helps eliminate some shadows:
