what am I doing wrong - Vingnette

Thanks Peter, another setting I wasn't aware of. I'm wondering now if the manual for the K5 mk 1 is very different to the K5IIs, I've downloaded the PDF version but not read much of it yet. As said earlier will be shooting in the garden tomorrow.

Camera custom filter settings don't affect raw files, other than perhaps in PDCU if you request it to.

I'm not familiar with most PP software. But PDCU allows you to extract the embedded thumbnail from the raw file; quite sure that others offer the same functionality. If the vignetting shows in the embedded jpeg, it's a camera / lens issue. If it does not show in the embedded jpeg, it's a PP issue.

At least you can eliminate one of the causes of the problem this way.

Are you saying it was not set to zero?

Yes, when I looked it wasn't zero. I've no idea why these were set the way they were as I've never fiddled with setting. I tend to use the defaults.

Took a couple of jpegs and raw files this morning and opened them on the main pc. All seemed as it should. So it seems to be a software problem on the laptop. I don't think there are any files I need on there so time for a full restore I think. Bloody windows (h)8

Glad to hear you've got to the bottom of it, but Windows will not have changed settings within an application, the user can and often does, Windows itself can't.

Unless you have other serious issues with your Windows installation, your imaging problem is not a good reason to do a complete reload.

I believe my computer, at least the brower, was 'hacked' as any web page I opened was littered with those dreadful key word popping up adverts for sites I have no interest in. That made me think perhaps it has been more than that. The first thing I'll try in unistall all the imaging software and do a full re-install of that and see how it goes. Thanks for your interest in my problems.

In error I have just had the same problem. Knocked off lens hood picked it up and put it back on 90 degrees out. In Photoshop RAW 6.5 there is a post vignetting tool and I used that to correct the mistake. I had not realised the lens hood was so close to the limits.

As to tyronet2000 problem had same problem went into addons and removed the program but next time I looked back again so went to options security and exceptions and cleared all exceptions seems OK fingers crossed.
