    Where could film have gone if Nasty Digital hadn't arrived !

    I was scanning halide photo's, and making desk-jet 'prints' from them in the mid 90's.. the dry-to-dry mini-lab was in the high-street by about the same time, and chemical-digital processing was probably starting to creep into mini-lab machines, by at least the millennium, along with thermal...

    Where could film have gone if Nasty Digital hadn't arrived !

    As far as image quality is concerned, there's still argument that digital has yet to achieve the 'ultimate' IQ that film might... its just a question of cost and convenience.... 'Consumer' film cameras were headed down that avenue for decades before digital, with ever smaller and cheaper film...

    Beginner Help!

    Lol! Many decades ago, after university and a few years of bad-beer and even badder bands in the SU bar, learning all the stuff I was told would pay the bills... I signed up for an evening-class in this faux-tog-raffy lark.... to learn something that wouldn't! Entering the classroom, I met an...

    Beginner Help with landscape settings

    Its the same thing.... its a question of 'Metering' and the way you translate that meter-reading to camera settings. The SI unit of light intensity is the Lumin. If you ever chance across a scientific or industrial light-meter, that's how it will be 'calibrated', with a scale marked in Lux...

    Beginner Help!

    Don't fret, the 'Go-Manual' mantra catches many. And, in an age of computer-trickery and ultimate automation, having a camera with manual-twiddle-ability gets far too many exited about having something to do, that they 'feel' makes a difference.... when it probably doesn't, much. The exposure...

    Beginner Raw/JPEG

    A Digital camera doesn't take a photograph. It records a huge data-table of numbers, for brightness levels across a scene... a 'computer' then takes that data-table and lights up pixels on an electric screen, 'Painting-By-Numbers' a representation 'sort' of like what you saw through the camera...

    Beginner Just starting out.

    The defacto start-point is an entry model DSLR..... Then you have choice between Nikon, Cannon and 'Other Makes', and chucked into that conundrum, is the 'mirror-less' question, championed by Olympus and the 'Micro-Four-Thirds; aficionados, with MFT and mirrorless cameras now oft offered by...

    Negative viewing device

    Two sticking points are the scale and inversion. Somewhere in my box of junk, I have, what I suppose was a magazine cover freebie 'film viewer'... it's plastic strip, that 'folds' in three and clicks at 90 degrees to make 3 sides of a box. Bottom side has two rails in it, the width of a 35mm...

    What and when was your first serious camera?

    {Bisto-Ahhhhhhh} That's like the chap-in the mini-lab explaining ASA dial, exposure compensation to me for the ski-slope shots; It does make you wonder how much we have lost, compared to gained, with tinternet, and on-line buying....... But then, last time I went into a camera shop, I was...

    What and when was your first serious camera?

    Olympus XA2; 1981, it was my eleventh birthday present. I chose it from a selection offered to me in the camera shop that included the Pentax 110 SLR, that I think my Dad wanted, because it was an SLR and diddy, and I think it there was the the first Auto-Focus compact Minolta. I picked the...

    Beginner Developing time vs developing dilution

    Once upon a time, long, long ago.... when film was all we had, and the internet hadn't been invented; My day-job was working on the development of missile guidance systems, at night, I went troglodyte and descended into my darkroom..... Enthused about push-pull processing, I tried to 'crack' the...

    What causes light leaks to produce different colours?

    I always found that the question was ever more sneaky depending on how high a level the qualification you were working to,, and what the tutor asked is often not 'quite' the question they want you to answer.... And there;s actually two or three pretty fundamental questions in there. a) As sort...

    Beginner EOS450D update/upgrate ideas...

    Again I dont think, this is so much a problem with the camera. You are using a one-size fits all 'walk-about' super-zoom, lens that is a jack-of-all-trades-master-of-none, 'all-rounder'; it's not a particularly 'fast' lens for low light... which I am a BIT sanguine about. f16-Sunny, suggests...

    Advice on f.stop / aperture

    Your camera is a small-sensor 'bridge' camera with inbuilt , mega-range, zoom. The 'big aperture' effects we presume you are after, are shallow-focus effects.. as has been suggested, go read up on Depth-of-Field of DoF. Essentially the DoF you get around a subject is proportional, first to the...

    Surggestions for a manual M42 mount manual camera please

    I have had a Sigma MK1 for thirty years, it's possibly my favorite camera, it has a meter, as do most, I believe. Japanese copy of the Ricoh, has all metal leaf-blade shutter and recoil like a .303! I was actually in local camera shop buying film and rummaging through the bargain baskets once...
