    I'm starting this thread to encourage us to share tips and ideas for photography and art related subjects.

    Under the Architecture thread there is an interesting discussion about digitally scanning slides. BTW there is scope here to discuss scanning film negatives, which I've done in the past (scanned, not discussed ;) ) to at least index rolls of film which I've inherited - call it conservation if you wish.

    Apart from this there are film and photographic museums, conservators etc working on preserving our celluloid heritage, before everything spontaneously combusts!

    It looks like there is a flourishing arena which could be explored in the forum. Surely, iPads have a place here, at least as excellent storage and viewing devices of the archived material. Also, iPad cameras do a darned good job, and I'm sure the cameras and the technology behind them will improve in leaps and bounds, to render then excellent for scanning and studio work.

    Lets get to the point here. Is there any mileage in discussing the different aspects of imaging?

    Suggested topics to include:-

    1. Scanning and digitising film and prints.
    2. Apps which you find useful to help capture and process images.
    3. How good is the iPad for these processes, compared with dedicated film scanners, cameras and processing on a computer. The iMac is, so I'm told, the best piece of kit to deal with images and graphics.
    4. Storage and sharing of processed images.

    Now, please stick to the forum rules. Do not spam apps etc. lets keep discussions flowing.

    I'm posting again. I am looking at using a camera or an iPad to photograph slides. I have boxes of slides which I intend to digitise cleanly and sharply. So, I've dabbled very quickly. I used the iPad to take a snap of a slide. I used Amplivision, and I used the camera. Here are the results:-


    image-4117974560.jpg

    Taken with the camera - not via an app.




    image-994182236.jpg



    image-8031900.jpg

    These 2 were taken using AmpliVision.

    The results are grainy and dark. I also need a strong light, preferable bounced off a white surface to evenly backlight the slide.

    I realise I need to steady the slide holder and the camera/iPad to get crisp pin sharp results. I think I will need to adjust the photograph for contrast brightness, grain etc....

    Wow...Richard....I have several boxes of slides I took back in my college days that I would like to convert to digital...I had been thinking about wasting $100 on a box from Amazon to do it...never thought about trying to use a camera and/or iPad to do it. I wonder if a macro shot would work well for this? As you say, you would need a strong light source and you'd need to get the focal plane adjusted just right...

    I have an old slide projector around here some place...and I could project them on a dark wall and photograph them....

    I seem to remember these little light boxes that you could put a slide into and cover over your eye...maybe put that over a camera with a macro lens on it...

    Good thread...

    For copying slides, I think one key point is sufficient illumination, which you're not going to get without a bright light source. I used a cheap flashlight (torch) with 3 AAA cells and 9 white LEDs. (I tried to attach a photo, but the forum software got all cranky.) Though the light output appears too blue, the color balance is actually pretty good for this purpose, and in any event can always be tweaked in Photoshop. To capture the most photons passing through the slide, the camera needs to be as close as possible to the slide, in macro mode. This favors any point and shoot camera over the iPad's camera, and their ISO settings are typically more flexible as well. My Canon A520 still wouldn't get close enough, so I shot through an old slide projector lens. Fiddly, but it worked. If you have lots of slides, be prepared to change flashlight batteries to maintain good output.

    Dust is vexing. I used a Zerostat, a piezoelectric ion generator sold for removing static charges from vinyl LPs, plus puffs of air from a rubber solder sucker to blow dust away. Canned air would be even better. I cleaned both sides of each slide before shooting it, and between each roll of slides I recleaned the slide copier's diffuser window. The more dust you remove before scanning, the less you'll need to retouch with the rubber stamp tool in Photoshop, which is relatively easy but time consuming.

    Try and get your slides in the correct order BEFORE scanning, so their file names and creation dates will be properly sequential. If you load them onto your iPad for display, iOS will use the creation date to order them within the album. The only way to change the order is to use a utility to edit each file's metadata manually, a real PITA. If you want to add text and a semi-fancy layout for iPad display, check out Pholium in the App Store. I can write up a vacation trip and hand the iPad to a friend to view it, without having to narrate each photo.

    Great idea for this thread! Have already gained much. There is nothing incompatible about iPad enthusiasts being interested in photography. This will be one of the threads I will be visiting first off when surfing the forum.

    Thank you all for your posts. This a great start to the thread, with some ideas which I will be trying out.

    I have a backlit manual slide viewer. I may try using parts of it to hold slides for copying.

    Using my camera's macro or super macro focus setting seems to be a good way to go.

    Thanks for the input.

    I have a very large collection of Kodachrome slides and would be very interested in the best and easiest methods of converting them to digital. Tis is a great idea for a thread, Richard.

    In my considered opinion, save up and buy a proper scanner for slides. Bad scans/images/copies mean more work in PS or something else. I have more slides than I can count and when I get around to scanning them, I'll try to find the best tech out there. OTOH, some people can get by with all sorts of things. Richard's way is ok I suppose. No offence, Richard.:eek:

    I know a man that makes dye transfer prints. On homemade film using a scanner he built. The quality is beyond compare.

    I was thinning that there must be a homemade approach to the problem. I have many slides with serious issues that I can fix with chemical treatments or converting the slides to individual color channels to improve the quality, but it takes work and not enough time left in the era.

    Dust is an issue. One thing I have seen with many old slides--especially those processed by Eastman Kodak an, yes, Technicolor, are scratches. Interestingly, what is often scratched is the lacquer EK/TC used as a protectant. You can remove the coating and remove most dust as well as most scratches.

    There are several approaches: use a camera and macro lens; use a dedicated high resolution scanner, or some other device.

    Or, you can take a photographic approach and do things old school. Sadly, the proper materials are no longer made and the process becomes daunting when your collection is vast.

    Here=this thread or here=not dead and still rabel rousing on the forums?
    :D
    Photography is why I did for many years and these issues are not new. Computer technology is a recent factor that both makes it easy to use your slides; at the same time, it is why I see so many bad duplicates.

    I miss the old days. that said, in the old days we would put pen to paper and wait for replies via the Postal Service.

    I've been tinkering.

    I worked on this slide on the iPad, using PhotostudioHD to sort out brightness, contrast and colour. I then used Snapseed for cropping and further colour adjustments.

    The focus isn't so good. That's probably thanks to iPad shake! :)

    Is there a new feature for viewing images in a thread.? There is a "See All" button to press. :)

    Go through them and seperate by exposure. Not every slide will be perfect; some will be over exposed and under exposed. So seperate them so you do you do not have to make changes for every slide.

    If you have lots of slides, consider a local scanner rental and give up your weekend.

    I've been experimenting some more. I used my Canon Powershot in normal and macro modes. OK, the macro image is not well aligned. Also, the macro image is not as sharply focused as the one on normal mode.
    I went on to crop and process both images in the 2 photo apps on the iPad.


    image-3930894183.jpg

    The normal mode version.



    image-1469965146.jpg

    The macro mode version.

    In Snapseed, I used the drama preset image processing feature with both photos.

    I was looking at the ION scanners. The initial reviews looked promising, as did the £40.00 price tag.

    I then rechecked things and came across this site which looks at a wide range of scanners. http://slidescannerreview.co.uk/

    I think I will persevere with my Epson scanner and buy an air jet. :)

    Thank you Richard, bit coincidental this. I was planning to do the below pics tomorrow with daylight (now 8.30pm Mon and dark). But quickly lined up my babies:) on the dining room table under fairly subdued lighting.
    [​IMG]

    And despite the poor lighting I think the iPad camera gives a reasonable idea of what I have here.
    [​IMG]
    The above is the menagerie.

    That little lot taken from the front:
    [​IMG]

    My first OM system camera the OM2n beautifully finished in top quality chrome with revolutionary "off the film plane" exposure, used by many professionals in various theatres of war. A tough little jewel still works as well as when I bought it new. Here.
    [​IMG]

    My next purchase was the magnificent Olympus OM4Ti with a tough titanium body favoured by professional photographers like Britain's David Bailey. It had advanced features for its time including averaging of chosen spot metering up to 8 spots for great picture control and a revolutionary flash sync of up to 1/2000 sec, which flash unit I also still have. I loved this camera and have fond memories of tramping the countryside with my Manfrotto tripod, still going strong, trying to express myself photographically. And the number of camera club embossed winner's drink coasters scattered around the place show I had not done so badly while having great fun. Here it is in all black:
    [​IMG]

    And of course my new purchase, a week or so old, my first serious digital camera, the Olympus OMD-EM5 system camera, still with those magnificent Zuiko lenses, amid the sharpest in the world. And a logical extension of the previous OM system cameras mirroring them with that lovely retro look that is very satisfying. It's an incredible camera with a 12-50mm (24-100mm equivalent) standard lens which, like the body, is water and dust proof. It boasts the world's fastest auto focusing system and has a most advanced anti-shake 5way system built into the body so you can use any lenses you want with the right adaptors, including all my Zuiko lenses from my other cameras. Here's my new toy:
    [​IMG]
    [​IMG]

    I was very disappointed in Olympus when the digital revolution came about and it abandoned the OM system concept for a series of measly little handbag cameras, meaning my lovely gear and lenses just sat in the cupboard and, apart from a nice little Panasonic non SLR snapper, I had virtually given up on photography. The enthusiasm is coming back now and, although the legs would not be able to do all that prior countryside tramping about with a tripod and camera bag, I'm now looking forward to more shutter clicking in my own way.
    Richard, I'm sorry this has turned out so lengthy. But hey! That's my new shooter.;)
