It's also an age thing, though, older models start to exhibit quite a lot of noise/grain as soon as turned up over 400ASA, whereas many newer ones are fine at 800. They are often acceptable 1600, too, though that can depend on other factors such as subject type, lighting and whether you're intending to make big prints off the files. I use an old Nikon D7000 (which is over 10 years old) and has a DX 'crop' sensor but still seems to produce reasonable pics. I particularly like the perspective control facility in the camera which you can straighten vertical lines so they are not overly converging or diverging. With regards to grainy pics I do tend to find that occurs if there is insufficient light and the camera is struggling to take a photo within its design limits. Generally you can never have enough light for photography (painting with light and all that) especially for models and layouts. Might be worth Andy lighting the scene with some extra lamps (and not forgetting to set the appropriate white balance). This quick snap (below) just taken is at ISO200 (the camera does go up to 6400), f22 on aperture priority and left on a tripod for the requisite exposure time that the camera decrees is necessary with a 40mm micro lens. It has been cropped (just a little) and reduced in size as per the forum requirements: HTH 4 8 Link to post Share on other sites More sharing options...

As you say, it's down to age. Regards, Tony. Age of camera definitely has a bearing. Sensor technology moves on all the time and if one skips a generation the differences can be very apparent. If you tested the limits of your D3 against a D5 or D6, there would be differences. However, if yours performs up to or better than the requirements of the way the image will be used, any improveent delivered by the newer camera is academic. The thing with a full frame sensor vs a smaller one delivering a similar pixel-count is that each pixel in the former is physically larger so doesn't have to work as hard. To summarise, a good big 'un will always beat a good little 'un, but if the little 'un delivers what you want/need, there may be little benefit to be obtained from the additional investment and/or bulk incurred in moving up. To give an example, A4 prints of 7802 'Bradley Manor' taken on my little Lumix Lx100 compact (Micro Four Thirds format) and my mate's full-frame D800 + 24-120 zoom costing six times as much were very difficult to tell apart, but if printed to A3 or A2, I'd expect/hope there to be clearly visible disparity!

RMweb Premium thegreenhowards Posted December 27, 2020 RMweb Premium Share Posted December 27, 2020 I was sufficiently encouraged by all the camera comments to go and try some experiments with the D80. It turns out that although I was setting the ISO to 100, I had set an auto ISO override somewhere else in the complicated menu structure. In the end I managed to do a factory reset of the settings and set the ISO to 100. The results are dramatically improved. Here is a shot of my Yorkshire Pullman taken just now (F25, 4 secs, LED floodlight, 30mm lens, ISO100). The results are much better than I was getting. Here is the identical picture taken on my iPhone. I prefer the colour balance on the iPhone, but the depth of field on the SLR wins out. I will be using the SLR much more in future. Sadly, I can't now work out how to set the camera back to provide a 'before' comparison so you'll have to take my word that it is a significant improvement. Thanks for all the help.

It purports to be an ex-WD 2-8-0 somewhere resembling West Yorkshire, and it includes two joined-up photos of the Bachmann engine and wagons to stay sharp, and I offer it as an example of focus ... and the pleasure of creating an image, even though it cannot be of anything actual. I always tended to excess... Here is a more pure example of enjoying a model to create an image, redolent in this case of a G F Heiron painting I vaguely recall from my youthful reading of 'Model Railway News' about 1963.

Andy Glad to see you’ve sorted the camera settings out. The D80 remains a really nice, usable camera even today, my father-in-law has used one for many years, only recently adding a D7200 to his bag. I had the same 10 megapixel sensor in a Sony A100 and got a lot of good images from it - neither of these cameras does well above 400ISO though. One thing to remember is that ISO isn’t a real thing with digital cameras, there are photons landing on each pixel and then gain (amplification) is applied to the photo current that is generated. The cleanliness of the output signal is then dependent on the intrinsic and largely fixed noise of the sensor element plus any non-idealities in the amplification chain. If there is little light falling on the subject, either because the overall light levels are low, or part of the subject is dark, the noise will tend to dominate. Putting it another way, setting to ISO 100 and under exposing by one stop may give identical results to exposing correctly at ISO 100. As another poster commented, more light is usually better! 1 Link to post Share on other sites More sharing options...

Tony Wright Posted December 28, 2020 Author Share Posted December 28, 2020 Progress with the Southern Pride Mk.1 BSO continues..................... Roof now screwed in place (it unscrews, of course), with those nasty roof ribs largely gone. No gangways are supplied (just the folded paper concertina sort). I had some spare plastic ones (from where is anyone's guess), so glued these in place, then added the concertina ones. Yes, once lowered, the bogies caught on the floor pan (and my couplings). The wheels were still well-clear. I just nibbled bits off the bogie to clear, and filed some bits off the floor pan. At the towing end, I fixed a Bachmann gangway cover (should ever this car be last in a train - necessitating removal of my coupling). The roof isn't quite seated properly yet. In comparison with a Hornby BSO, it's still a fair bit taller. The nibbled-away bogie is apparent here. I can't really lower it any further. But then there's no need, since it matches a Bachmann Mk.1 quite well (the roof is still not quite seated properly). Since its position will be in a mainly modified Bachmann Mk.1 rake (it's the 3rd car), then it should suit quite well. It'll (correctly) replace a Bachmann BSK, lettered with a 'W' prefix! In all the years this rake has run, nobody has ever noticed this anomaly; nor did they on Retford, where Roy Jackson once showed me two identically-numbered 'W' prefixed Bachmann Mk.1s, adjacent to each other in a rake! As with any loco I build, I always thoroughly road test any carriages I'm building, long before they're completed. Is it worth building something like this carriage these days, especially now that Hornby produce an RTR Mk.1 BSO? Before, perhaps? As I mentioned, I've had the kit over 20 years, and things move on. At the time the likes of these SP cars were exceptional value for money (are they still?). As a 'layout' coach, I'm sure it'll be fine, though RTR equivalents will probably be better-finished. That said, as part of a 13-car rake, who'll notice? I'll certainly finish it and report accordingly.......................... For those interested, the picture above was taken with a Nikon Df shooting a TIF file; I used an 18-35mm Nikon zoom (set to 35mm), with the ISO set at 100, and a five second exposure at F29 with the focus at 2' 6". Shadows were lightened by pulses of fill-in flash during the exposure, with the ambient room lighting providing the principal illumination. 17 2 Link to post Share on other sites More sharing options...

Like many models which purport to represent the same things, if it's a whole train perhaps best not to mix and match?

Originally, if memory serves, the SP coaches were the best ones if you wanted a flush glazed coach, as the only rtr ones at the time were old Hornby or Mainline, so the SP ones were a Godsend. As stated above they are no longer available and the current rtr ones are much superior, although I still find it difficult to accept £40+ for a coach! 1 4 Link to post Share on other sites More sharing options...
