Purple Fringing

[joroma]

Just messing with my new Canon A85 and one shot of a building has a very noticeable purple finge when you zoom into it. I seem to recall hearing about this happening with some shots due to chromatic aberration at wide apertures but can I edit the fringe out using Photoshop 7 and if so how.

Are you shooting raw or jpeg?

You can find a method to remove purple fringing in Photoshop here: http://epaperpress.com/psphoto/index.html
Choose "Preparation" in the menu on the left, and "Purple Fringe" in the menu that appears below it.

Steven, the A-series PowerShot cameras do not have RAW mode.

Are you shooting raw or jpeg?The A85 is not capable of shooting RAW images.

Here is the link to a free plug-in for Photoshop specifically for purple-fringing:

I'm not familiar with the A85, so thought I'd ask--because Adobe Camera Raw has nice de-fringing capabilities.

Thanks for the link though--I sometimes shoot jpg (and have lots of old jpgs) and it's nice to know you can address the issue in PS. PaintShop Pro has a very nice de-fringe function. It has been the one reason I've kept PSP on my computer after getting PS CS. Guess I can get rid of it now!

I tried this last night but when I dropped it into PS 7 I keep getting an error message not recognised by windows (or similar) and it doesn't appear in my drop down menu of Plug-Ins. Any ideas?

- Go to the bottom of the page at http://www.sd3.info/pf828/PFree/PFree0-1.html
- Right-click the link "PFree 0.2"
- Choose "Save Target As" from the popup menu
- Internet Explorer will ask you where to save the file (with the extension ".8bf"); navigate to your Photoshop plug-ins folder (usually "C:\Program Files\Adobe\Photoshop\PlugIns\Filters")
- (Re)start Photoshop

What is exactly the error message that you're getting? Maybe the file got corrupt while downloading it. Try downloading it again...

I'm planning on loading PS 7 onto my new laptop at work today. I'll try loading the plug-in later today and see what happens.

It worked fine on my old computer when I loaded it 3-4 months ago...

Just tried it. It worked fine for me.

It shows up as the last filter in the Filters pull-down list under "FiddaFilters".

Are you sure you pasted the file in the correct folder?

C:\Program files\adobe\Photoshop 7.0\Plug-Ins\Filters

Thanks for your help guys. I've printed this thread and will try again tonight after redownloading the file.

Downloaded plug in again and reloaded works an absolute teat. Ta very much.
