    I was thinking more £ for £ rather than f-stop for f-stop . Really shallow dof is not something I use that often, but sharp wides for low light I do make use of, but they are pricey for FF. Am a month in to using a current generation APS-C alongside FF, interesting and informative journey so far, I may just jump ship from a certain well known brand!

    Take care of the fish, and the fishing will take care of itself.

    Said I'd post something on B&W conversions, will do so in two posts. This one goes back to the principles of film and the effect of putting a colour filter (which come in red, yellow, orange, blue and green) in front of the lens - digitally this is done in-camera or in post-processing. I've shrunk these images to 800px on the long axis to hopefully not take up too much space. For this, I've chosen an image that has red, green and blue in it to show some of the impact of different approaches to conversion. The scene is from the Retort House at Biggar Gasworks - now in the care of Historic Scotland.



    To start, we can look at the effect of simulating different colour filters with a simulated black and white file (Fuji Acros). In this case these are done in-camera, FujiFilm are unique in offering these simulations, but it is possible to emulate using software on a computer, the best software being bespoke B&W conversion packages but most image software will offer some form of conversion. The first image is a straight B&W conversion which simulates the contrast Acros is famed for so yields quite a good conversion. Nikon in-camera conversions will yield different results, generally lower contrast, though they usually have the ability to add filters.



    First, the effect of a red filter - this will give a lighter grey tone for any red in the image (in this case the boiler) and darker tones for the complimentary colour (blues/greens) - most commonly it is used to darken blue skies in B&W, though it can overdo it at times, darkens the non-Victorian plastic bucket nicely!:



    Next a green filter, which will do the reverse, yielding darker tones from red and giving lighter tones from green and blue:



    This is where creativity comes into play with B&W conversions, neither of these conversions really gave me what I was looking for in this scene - the red filter lightens the boiler too much, the green is better but by darkening the boiler I felt the image lost some depth and that darn 21st century plastic blue bucket was also too prominent. In the next post I'll show how I approached this particular scene.

    Hope this helps.

    Yes still in York,does a lot more photography these days now.Needs to put curlers in his blonde locks lol.

    Found an app which is quite good and free ,So I can understand what your saying about the greens etc Iain.Had a little play with some pictures on it just to get used to what bits do,still more to learn about it but it certainly helps with playing around with the colours and also light and apertures and focus.

    Are you hand holding the camera in the open or from a car, if from a car its worth buying or making up a bean-bag, that would sit on your car window, certainly would make a difference in sharpness.
