Very Impressive photos of an excellent layout Vitalspark. I have a Nikon camera, a D3400 with the standard lens it came with. I am slowly learning how to use it and I have a good level of light in the railway room so I can try and get ISO down and f numbers up. I have a bit of an issue with focus; my eyesight is not sharp and I tend to have to use the screen not the viewfinder. I know its supposed to be automatic but it never seems to focus on the bit I want it to, more study needed I guess. Annoyingly I find that it can't be used in tethered mode or I would connect it to a monitor. Slowly I am getting the hang of video a bit. Seeing what I'm doing and focussing is again my main issue. The down side is of course that if I get better at photography I will see even more of my mistakes and have to fix all sorts of things.

No its the use of a 45mm lens with a very small aperture..up to f43..and a long time exposure in this case 6 seconds. All this is designed to give good depth of field which was the original post enquiry but I agree it can offer too much and in doing so has the effect of foreshortening the image. Somewhere in between is my preference. Thanks for your nice comments. Dave.

I think the Nene Valley one may have gone to Holland now, but the Bressingham one should still be there. I dug out a couple of pics of the TCDD 8F at the GC, dated 9th April 2011, and these should be included below. The other 8F in the lower shot is 48305, which I think still lives there.

When providing images for a magazine we photographed Alloa with among other things a low angle lens with a min aperture of f43. This was used for close ups but also allowed good depth of field but actually worked too well at times with the very long exposures giving clarity to a bus win an over bridge 30 feet away making the picture look unrealistic! Cameras were Nikon bodies and all lenses Nikon but Canon Fuji or any of the other big names will all do similar lenses. We were fortunate in that we had access to the camera bodies and hired the special lense needed which cost wise was surprisingly reasonable. However..a decent camera phone will often give you exactly what you want without any of the expense and it can be slotted into areas where a dslr wont fit. Nikon D90 and stock short zoom f22 @ 0.5 sec showing reasonable dof. Again Nikon body but at f29 @ 6.5 secs. Layout is 34ft long and far end in pic close to 30feet. Finally a pic using the iphone and not even my later iphone X with the better camera but a 5S. The ability to get the phone into places where the big cameras can't go is a huge advantage as is its ability to auto compensate for low light and gives decent dof as long as you hold it steady.
