PS. Sorry Lawrence and Petermac but I have deleted your posts as you got there before I did. Please make them again here if you wish.
I have also made the tutorial a sticky so that it will remain prominent in the Model Railway Photography section.

I've always thought this forum deserved its own photography tutorial, rather than links to others, and yours is up with the best of them :thumbs

From now on each post will be related to photographing your layouts, or models, in which I will try and explain it as we go, looks like we could be going an a long journey.

Showing the difference between flash and available light.
I have put this up in a rather simple way, is fine with you all, or would you like it explained in depth.
Just a thought, if you have any subects that you would like explained, please ask away, because this will help me sort the next couple of tutorial's out, rather that steaming on, talking about things that you all don't want to know.
Hope you all enjoy

The images clearly show the benefit of trying to photograph without the flash.
Can you explain why when changing the F value from 5 to 11 you changed the shutter speed from 1/6 (of a second?) to 1 second?

To get a correct exposure, the camera must be set at a shutter speed and an aperture that matches to give a correct exposure, such as
shutter speed = 1/30
aperture = f4.5
If we forget about the ISO for the moment, and look at the above settings of a photo that we want to take, of a loco on your layout,without flash and using available light, with the exposure of above you could hand hold and take the photo, but the depth of focus would be very shallow, as per the second image of the post, but to get a far greater depth of focus ( more of the photo in focus as the third image of the post) you need to alter the aperture to say f11, which would mean that the shutter speed would alter as well to give you the correct exposure, something like 1/4 of a second.
This would mean that you could not hand hold the camera anymore, and would need something to either rest the camera on, or a tripod.
Hope that has helped.

My Powershot A620 has a maximum f setting of 8.0 but that has made a huge change to the depth of field already.

Can you all please put down the subjects that you want covered, and I will look into them.

back to topic. i like to weather and then show a loco once this is done. i have found that by using a white background this helps. so how would you take a detailed picture of a single loco\wagon to show the detail. i think if you are showing a weathered\detailed wagon it is best to keep the area around the subject clear (no scenery) as this distracts the vision.

2nd Question first
I would use a mini studio, and this would make a good tutorial, as I don't have one myself, so if you and a couple of other members would like to use one, then I will look into it for you.
1st Question
My knowledge of all the camera's that are available is limited, but I will have a look at the Canon G9 and also see what is around at the same price for you.

Look at these reviews
http://www.dpreview.com/reviews/canong9/
But for a little bit more you can have this
http://www.dpreview.com/reviews/fujifilms100fs/
The Canon G9 is a very good compac camera, but you are a little limited with the highest f-stop being 8, and also the ISO, but with the Fuji, the f-stop goes to f11, and the ISO goes to 6400 ( which would allow you photograph a black cat in a coal bunker) , and you also get a much larger zoom and a better Marco,but at the prices that I looked at it looks as if the difference is around £100, or the same as the new G10. it really comes down to what you want it to do at the end of the day.
Any more questions Matt just ask away.

Might have to change my Christmas wish list.
