Default Canon G5 - Eliminating or Minimizing Purple Fringing

Hello everyone! I just took the plunge and bought my first digital camera (Canon G5). It isn't the Digital SLR (10D) that I dream about (due to a limited budget) but I managed to pick it up for around $420.00 USD. I'm very pleased with the manual functions of the camera but not as pleased with the results of the photos I took. I only shot around 50 photos fresh out of the box but I noticed purple fringing on at lest 5-6 of the photos I took.

If I knew how to post a photo on here I would, but what I am experiencing is a purple halo around reflective surfaces of the photos I'm taking. For example: a purple halo around the china sitting on a dinning room table.

Is this effect to be expected of a digital point and shoot?

I know the digital point and shoot is not going to come close to my film SLR with prime lenses but the purple halos and fringing I'm experiencing is very obvious.

Is there a way I can elimiinate or minimize this effect of the Canon G5?

I don't want to turn this into a what camera should I buy post since my main question is how I can eliminate this phenomena but is there a 4 or 5 megapixel camera with some manual controls that exhibits this effect much less (for under $450.00).

Default Your G5 Issues

Hi there.

The effect you're noticing is called 'Chromatic Abberation".

It is a noted issue with the G5 that generally takes place when shooting picutres that have high contrasting situations... i.e., branches against a pale sky.

Outside of reducing instances of high contrast; I have not come across a sure-fire way to eliminate chromatic abberation.

I am a Digital Camera salesman and have seen the issue come up, including my own personal fieldtesting with the G5.

While I hope the explanation helps you out; I'm afraid I don't have a solution for you.

When you tried to post an image you needed to click 'img' paste the url and click 'img' again.

Purple fringing is a problem but you soon learn to know when it's going to happen (long sharp edges into the sun) and take some sort of action - using aperture priority will help - your camera has that - look at the shot in auto mode & see what the camera chooses for an aperture (F3 F5 etc) & go to aperture mode & choose an aperture number higher than that - take some comparative shots.

Thanks Tim and Ken for your replies. I love the camera and definitely want to keep. So stopping it down a bit will help do away with the chromatic aberations I've been getting? Also, is there a photoshop plugin that will help out with what I am experiencing?

Thanks!

Ken
