alan_olander1664878205 Posted May 1, 2007 Share Posted May 1, 2007 It's chromatic aberration, and it's a property of your lens. Link to comment Share on other sites More sharing options...
Tim_Lookingbill Posted May 1, 2007 Share Posted May 1, 2007 I get that using both my Pentax K100D's kit lens and a Vivitar 28-135 macro zoom nondigital lens. I don't know if this is expected but it seems a common issue with backlit subjects with any camera. I even get this on several scans of 35mm film taken with P&S's and an old Yashica SLR camera I've used in the past. Also I've seen it even worse on cable TV broadcast like on the Learning Channel and Discovery where I'm sure they use very expensive camera's and equipment. From the size of the blow-up, I'ld say it's hardly noticeable. Link to comment Share on other sites More sharing options...
simon_hickie1 Posted May 1, 2007 Share Posted May 1, 2007 I have the same combination with similar outcomes. It's the lens. Link to comment Share on other sites More sharing options...
sfcole Posted May 1, 2007 Share Posted May 1, 2007 It may be worse at certain zoom settings or apertures. On my 16-45 Pentax lens, it seems less at 45mm. Link to comment Share on other sites More sharing options...
tom_jenner1 Posted May 1, 2007 Share Posted May 1, 2007 You can try a higher F stop. Better yet, drop $110 on a 50/1.8 lens. I never use zoom lenses with studio strobes. Even with the 18-70, I'll get fringing on the edge of a white plate on a black background. Get the 50/1.8 Link to comment Share on other sites More sharing options...

tom_jenner1 Posted May 2, 2007 Share Posted May 2, 2007 Hey Gunpreet, What we're all trying to tell you is that you're having this problem because of the zoom lens that you're using. Zoom lense are a compromise and one of the compromises, at least in the consumer zoom lenses, is that they tend to have a higher amount of fringing. If you're lens is a problem, then you need to get a different lens. A low cost, high quality lens that won't have these problems is the the 50mm f1.8 prime lens. With a high quality prime lens you won't have this problem in the first place. Problem solved! There are also a wide variety of low cost prime manual focus lenses that you can use, although they won't meter with your D80 (manual only). -Tom Link to comment Share on other sites More sharing options...
simon_hickie1 Posted May 2, 2007 Share Posted May 2, 2007 Not much you can do really, except in post-processing. Try an 18-70mm nikkor - I have virtually no fringing on mine. Also, you might try underexposing by 1/3 to 2/3 stop to reduce the CA from dark/light transition areas & then fix in software (best to shoot RAW).

jeff medkeff anchorage, a Posted May 3, 2007 Share Posted May 3, 2007 If the D80 is digital, and you shoot raw, and you convert with Adobe Camera Raw, you can correct this by using the tools on the "lens" tab of ACR. Link to comment Share on other sites More sharing options...
john schroeder Posted May 3, 2007 Share Posted May 3, 2007 If you shoot in RAW you can correct for it with Capture. Photoshop also has a tool for removing CA. Link to comment Share on other sites More sharing options...

jerryjohnson Posted June 21, 2007 Share Posted June 21, 2007 There is a filter that was designed for chromatic abberations such as that. It was made specifically for astro-photography where the abberations like that would 'bloom' the stars. It's called a 'minus-violet' filter and is made by Lumicon. Basically it cuts out the high end of the violet spectrum where chromatic abberations occur. I personally haven't used it with normal photography, I have used it on some of my astro-photography done thru a refractor scope similar to older telephoto lenses. http://lumicon.com/telescope-accessories.php?iid=LF3135&cid=25&in=Minus+Violet+Filter+72mm&hn= It's not the normal type of solution I'm sure. The others have already sent some sound solutions to the problem but it's an alternative. Just my $.02 worth.. Link to comment Share on other sites More sharing options...
