    So, I have been at it again!...... Orb Weaver (UK) overall body length from pedipalps to spinnerets approx 10mm. This is a collection of 23 Images taken using Olympus OMD EM1 mk2, Olympus OM60mm F2.8 Macro lens. Focus technique= ring not rail. Stacked with Zerene Stacker Pro version (D map), cleaned up and colour balanced using Affinity V2. any constructive comments welcome.

    This is my solution, Scanning 4x5 negatives with a Nikon D600 and a home designed / manufactured scanning plate using a commercially available A4 light table. produces huge files in excess of 240mb from RAW Nikon or Canon files The scanner produces 20 titles with appropriate overlap run from an Arduino and stepper motors. The accuracy is outstanding. A few observations that I found in improving the results; Always focus on the grain side (Matt side of the neg) At 1:1 ratio lens on FX Digital I use an aperture of f5.6 or f8, further than f8 causes aperture blade diffraction. Use the most stable tripod / support you have. Ensure that the plane of focus is parallel to the camera sensor. Focus using high magnification of Live view (on DSLR's this normally ensures mirror lock up which reduces vibration) I use Affinity Photo Panorama function to knit the 20 tiles together and generally this does a good job, but can get confused on areas of bland sky. I had to adjust the timer facility to ensure that any vibration has ceased prior to taking each shot and moving the light table. If you are interested I can send you via we-transfer a 240mb sized image. Good luck. Regards Graham L Furlonger VID_20211008_152927185.mp4

    I have a 2019 i Mac with 3 GHz 6-core Intel Core i5, 48GB of RAM and Radeon Pro 570X 4GB vid card. I have built a custom scanning device using an Arduino, 3d printed parts with an A4 flat bed light table (Ebay) and an old Canonscan UF2400 neg holder for scanning 4x5 negatives with my Nikon D600, it shoots 20 RAW images; 4 horizontally by 5 vertically producing a finished cropped file of around 240mb. The finished image is exported to TIFF. I have no problems with this and the overall processing time for the panorama is approx 2 mins. The only issues I am experiencing is where the scanned image has section tiles of plain sky and then sometimes AF misses them on the finished image? Just trying to work out how to replace the missing tiles! The produced image from a 4x5 neg will print out just over 2.5m long x 2m high at 300 ppl

    Thanks, I was encouraged from a really early age Jowday, When I first got the opportunity to see a black and white print develop infront of my eyes in a darkroom at the age of 11 I was amazed. I collected some basic stuff and was developing my own negatives and printing from them at the age of 12. I have done a full circle really, started on negative film B&W then C41, professed to E6 positives, then in the 80's went Medium format 6 x 4.5 and 6x6 ending up with a Mamiya RZ6x7. Then in the early 2000's purchased a used 4x5 monorail and then a 10x8 field camera (still have these and use them today) then in 2003 purchased a brand new Nikon D100 DSLR, sold loads of my film kit including my FM2n and Olympus OM4 (LOVED the OM) then progressed into D600, D800 and recently purchased a really nice Used FM2n and OM4 again. Currently have two ETRSi bodies too. Film is making a serious comeback although will never compete with the mobile phone snapper masses. lol Enjoy whatever you do, be lucky you started later... my kids will have approx 5000 combined negatives and E6 slides to sort through including:- 35mm, 645, 6x6, 6x7, 4x5 and 10x8! ha ha Regards G www.grahamfurlonger.co.uk

    Hi Firstdefence, answers to your questions... 1. Never seen a positive print from this neg. 2. Yes, lots on this roll of negs had a light leak problem. (It was taken with my Fathers very old Balda folding 6x6 camera Circa 1950 3. Nope scanning procedure is perfect and repeatable. works very well on E6 and B&W negs. (Post comment) I have now found a way to do this very easily and posted it. Thanks for your help.

    I converted from PS and vowed never to return! Found a really quick way of doing it in Affinity Photo, and posted. Thanks Jowday for your input.
  19. Graham L Furlonger
    ok, thank you for all your help. by accident I found a real easy way to do this... might be helpful for anyone else? I am not sure if it is the "correct" way, but it works for what I need and its quick! Select "colour picker tool" onto the film rebate, Select from main menu "LAYER" then "NEW FILL LAYER" change the layer options of this new fill layer to "Difference" Done! Just needed to play with the colour sliders in "Adjustments' and "Colour Balance" Done! Thanks everyone. PS I started photography at a very young age (5) here with a Coronet Flashmaster 120! (Circa 1950's) which I bought from a second hand shop with many weeks pocket money, LOL And here's the scanning setup I use.

    carl123, thank you so much for your time. I am still unsure how to do this myself? No one has come back and told me where the white balance can be found with the three eye droppers as explained in the photoshop tutorial, and although I very much appreciate your time Carl123, I still have no idea what you did to get to this photo. ....OK I give up. really cant believe its this much hard work getting a simple answer.
  22. Graham L Furlonger
    Thank you, but where do I get the menu that displays the three eye dropper tools for black grey and white from? thanks.
  23. Graham L Furlonger
    Thank you for all your help and posts BUT, no one has actually instructed me how to do this in Affinity Photo? please can I ask again, how do I do this (what would seem a simple task for photography software) in AF? thanks. Regards Graham. I cant believe its proving so illusive?
  24. Graham L Furlonger
    Ive uploaded the Image which took considerable time, @DWright please can you tell me why that was necessary? Thanks. Regards G
  25. Graham L Furlonger
    OK, thank you. I am still looking for some instructions on how to do this is Affinity please?
