Sounds like a glitch - please submit a report of the details to IT.

Here's my attempt. Not very happy about the halo round the mountain and the posterisation in the sky, but that's probably because of the small file size.

This was done messing about in Channel Mixer with red and green pushed right up and blue virtually removed. In other words, pseudo-IR.

It's just the relative movement of the various groups of elements and this depends upon the design of the individual lenses. Lots of zooms are shortest somewhere in the middle of their zoom range.

Likewise, most lenses have convex front elements, but there are a very few that have concave front elements. These tend to have enhanced edge performance at wide apertures.

But whilst we're on the subject, how do you rate the performance of the 55-300mm? Is it better than the 75-300mm that you bought off me some time ago?

It's a simple and logical system. I have all my images in the My Documents folder and label each SD-card full as opposed to locations, so for example:
SD K001 Portmeirion
SD K002 Haddon Hall 1
SD K003 Haddon Hall 2
contain all the original JPEG files. These are backed up to CD as well.
When files are worked on and finished they are in folders such as:
EPZ 2008-05
EPZ 2008-06
or
eBay 2008-05
eBay 2008-06
and so on.
It's dead simple and it works.

Shhh...Sue is sat next to me.....

That's quite true, but having said that we have had some success in very poor weather with any lens on out K10Ds. It just needs a modicum of care with the lenses, but they have so far fared pretty well in some atrocious conditions.

I help to run ADAPS, which is probably one of the largest clubs now in the North West.

We make an effort to welcome new members and provide a varied and interesting programme. I'm doing a Saturday Photoshop Beginners session this week, for example, which is a free extra for members.

For keeping in touch between meetings we have our web forum on our site at www.adaps.org.uk and you'll find on there a forum competition just like the one was here! (it's open to non-members by the way)

A club has to want to be open and welcoming for it to work and hopefully we achieve that. There are quite a few Pentax Users these days.

Best thing is to file a report for the IT team.

Shaky, I have no idea what you are trying to prove with that. Thus the thread closes.

None are saleable yet, the effects are a bit "blunt" IMHO. There is no substitute at a wedding for getting things right in camera as there is just no time to mess about too much afterwards, at least not if you want to make a profit.

Given that many people don't really "see" a photograph though, you might get away with straightening, levels and burning in the unwanted figures to reduce their prominence.
