A monitor displays an image at 72ppi, regardless of the size of the image.

So an A3 sized 300ppi image is interpolated downwards to 72ppi for display.

The image size and ppi are inter-related assuming that the pixel count stays the same. You can see this working by playing with the image size dialog in Photoshop. (Image>Image size)

Plus when you convert to jpeg the pics change again don't they?

They shouldn't, so something is wrong if they do.

You're displaying yet more wisdom there, Oggy!

It's irrelevant as far as the camera is concerned - the size of image that results from 72ppi for a 14.6MP camera is absolutely immense.

Some cameras show the figures related to 180ppi.

There's a very common error being repeated here. Resolution in the camera, on the monitor, in Photoshop, is measured in ppi - pixels per inch. 72 (or 96) ppi for the monitor, 300ppi for a print.

The printer lays down ink in dpi - dots per inch.

The sights are all well known and well photographed, so when I travel I look for the small details that everyone misses. Keep your eyes open, look above eye level to see things that can be easily overlooked.

Wherever you go, things are largely the same and the joy is in the small details. Interact with people (paulyrichard does this well) and let the photography be a consequence of whatever you do.

Oggy, you have the kudos of a correct answer, although I can't confirm the Spitfire bit. It is indeed an Aero lens from a wartime reconnaissance camera.

I just dont think its very fair that i should have to wait several weeks minimum for a replacement.

That hasn't happened yet, so do keep us posted on how this goes. Hopefully the response will be better than you currently think.

It's the 1st Edition Dungeon Master's Guide with the original cover. We have unused copies of that, the original cover Player's Handbook and Unearthed Arcana. These are in reserve for when the used copies wear out.

I've just bought a Pentax 52mm thread S25 close up lens off eBay. It's beautifully made and the results are pretty impressive. Don't underestimate the simple close up lens, although to be fair the Pentax one is a bit above the norm in terms of quality. Here I used it with the 18-55mm II kit lens at f11.
