Whatever the technicalities of the law may be, I would ask permission and, if necessary, get that from all the parents. If people start to object, then walk away from the situation and don't get involved with it.

Yes, Pentax Adapter K is the one to go for. They were about £20, but I don't know what the current price is.

I've read this carefully and reading between the lines the A you refer to may not be the next click after 16 or 22 on the aperture ring? Are you referring to the A/M switch that changes from auto to manual diaphragm control for very very old screw thread lenses? Is it in fact a screw thread lens with an adapter on the back?

The fact that you need to set using aperture ring to permitted and you still get F-- in the display gives us further clues that this might be the case.

If so, the answer is to focus with the lens set to "A" to give the brightest viewfinder image, then stop down using the lever set to M and take a meter reading at this aperture by setting the camera to M or Av mode and operating the "stop down" position on the shutter release dial.

Then take your picture.

Just as there was no substitute for having one's iwn darkroom, there is now no substitute for having a printer available at home. It enables the prints to be made exactly to your wishes, not almost right but, with practice, exactly right.

Commercial printing services can be excellent, but I like to have that final control. It also helps a lot not to have to wait for the prints to arrrive.

You do. Auto exposure is fine, adjusted by using the exposure compensation facility if required, as usual.

We take a laptop on holiday, one each actually, so that we can download and view the pictures, keep putting one on EPZ every day and keep in touch here as well.

For storage IMHO it would be best just to keep the SD cards safe and have plenty of them. All storage devices can fail and lose everything, but probably the cards least of all. They are the safest bet overall, and the cheapest option too.

A nice picture set, with exemplary composition.

If they were mine I would use "Levels" in Photoshop to up the contrast just a whisker. Not too much, otherwise they start to look unnatural, but a small increase will enhance the "bite" and the impact of the pictures.

If you don't have access to Photoshop or a program with a levels setting, then Brightness/Contrast instead.

You were? Wow! Bet the Vulcan wasn't half bad either!

Thanks, Martin.

I can now reveal that the errant image was shot on a.....Pentax 645N, or at least the portrait was. It was my last medium format model shoot, and the model is Kelly. It's from a black and white negative.

The flower was shot on the Fuji S7000 that appeared in the EXIF data and the two were blended in Photoshop 7.

Just in case anyone wanted to know!

I wonder if it had been two digital cameras which one would have shown up? Does anyone know?
