Slides, photography from the 50's???
-
Hi All, I wanted to opions on slide to digital image conversion, I have the hardware and can convert them to jpgs, some of them are 'quite dark' to quote Mum, I was wondering if I captured them at a higher bit rate 96 instead of 24 and used a different save format I could them use some software (Paint.Net, Hypersnap or something else) to get more definition out of them? Just wondering... (also who thought Slides were a good idea?)

Slides are awesome. Color negatives are Satan's own creation. I can't really help you. I haven't scanned many of my slides. I mostly scan B+W negatives.

Try the "Auto-Level" adjustment in Paint.net, it works quite well to fix the colour balance etc on old photos.

I scanned ca. 6000 old color negatives with an Epson V500 photo scanner. And some slides. One of the things you can do is a reasonable color/contrast/etc. correction even prior to the scan. In addition, you can use something like GIMP II (freeware equal to Photoshop) and really fix them up in any manner. What makes this a better route (if the images have any importance to you) is that you can operate on parts of the image, remove dust, scratches, and etc., as you so choose. Where I work, for a while, I used to have an occasional call for employees to submit really old pictures of themselves which I would restore. The restored images were published in the company quarterly with a "Guess Who?" theme. Restoration can be a lot of fun. (More so, if you're paid for your time).

Try GIMP[^], it's free and a good editor.

Just as general advice, don't save them as JPG file - it's a "lossy" compression format, so you are throwing away detail to start with. Save them as bitmap, or use a lossless compression format like GIF or PNG instead. When you've adjusted them - and nearly every paint package can do that - then save the "release copies" as JPG to shrink the size, but keep the lossless originals in case of other work being needed.

A "bitrate" of 96 - do you by that mean 3*32 bits per pixel? I've never seen a scanner that has that color depth! Usually it is either 3*8 = 24 or 3*12 = 36 bits. If the slides are underexposed, and you use the same exposure for all of them, you will only use a fraction of the density range in any case. All the scanners I have been working with allows the exposure to be set in the scanner. If all those dark shadows are more or less stretched out to a 3*8 bit/pixel range before they leave the scanner, the color resolution is likely to be more that good enough, at least for amateur use. If you are going to do extensive post-processing, you might want to use a 12 bit format for the working copies - but even though jpeg defines a 3*12 bit format, the support for it is far from universal. "Quite low" would probably be a good description. So when you are through processing, you should probably save it in 3*8 format. To capture 3*12 bits from the scanner, you will usually control the scanner from your photo editor, which must be capable of handing 3*12. The image is usually transferred from the scanner to the editor in uncompressed format (I think that my current scanner isn't even capable of returning scans in JPEG format!), and it is up to the photo editor to select a working storage format, which may be similarly uncompressed. Generally speaking, repeated cycles of JPEG unpacking - photo editing - JPEG packing is not a good idea. If you are going to do that, at least make sure that you set the JPEG quality to maximum while working with a photo, even though the JPEG files will grow in size. Also, scan at the maximum optical resolution that your scanner provides - but note that some scanners claim a much higher resolution than what is real, by interpolating between the actual scan values. I have seen scanners with an optical 1200 dpi resolution deliver an interpolated 9600 dpi resolution. This you might as well do on your PC - maye in a much better way. That depends on your software; some scaling functions do a quite decent job of e.g. identifying sharp edges and preserving that in the interpolation process. Slides are a good idea if they are shrap, exposed correctly and displayed on a high quality screen by a high quality projector in a "home movie theater". But since you get no opportunity to make up for incorrect exposure during printing (because there is no printing!), you depend on an automatic exposure camera - which was non-existent in the 1950s) or a photographer who knew how

If you're trying to save precious images, go with RAW at maximum bit depth. As other said you can enhance them with either GIMP or Photoshop, there is also a cool free image processing software called ImageJ which is mostly aimed to those who perform mathematical imaging but can read literally any format and do any kind of operations on images.

It probably has only 16-18 significant bits, I did work with a some imaging equipment with that bit depth. The light sensitive part of the high end X-Ray detectors can push up to 23 bits, and it's basically a scanner (X-Ray sensors are normal light scanners coated with a scintillator that emits light when struck by X-Rays).

My Dad (who took the images) was a camera buff (in the 1950's) and yes he bought my Mum one of the first Kodak Instant Cameras(?) I can recall my Dad's frustration when 'they' stopped making the film for it! The images were instant but faded over time...

You shouldn't pack-unpack-pack-unpack too many times, especially if you have set the quality low to minimize the size of the JPEG file. But then again: Some people judge the quality of compression (whether photos, video or sound) solely based on the file size - disregading both the software creating the file, and the method used, taking for granted that bigger file = better quality. For "natural" shapes, JPEG is actually quite good. Note one very important thing about JPEG (that also holds for MP3 and AAC audio and MPEG/H.26x video): Compression is not standardized. Decompression is! Two JPEG files may contain very different data streams, both decompressing to very similar expanded images. Two compressors may use very different strategies for creating a data stream that will decompress to the desired result. Simple software just find "something that works"; more advanced software may try out different alternatives, do the decompessing and see how much it differs from the uncompressed input image, and select the encoding that minimises the differences. Or set parameters to reduce losses below a given treshold. The basic idea of JPEG is that with a point light source illuminating a flat surface, the brightness will vary over the surface by a cosine function. With a distant, "flat" light source like the sun, a spherical surface will receive ligth varying with the cosine of the angle between the light source and the surface normal. A matte (non-blank) surface reflects light in given direction as a cosine function of the angle to the direction of the light. An opaque material, such as a white lamp dome, spreads light in a similar way. So, cosine distriubtions are very common. A photo of a smooth ball illuminated by a point source (or by flat light) could in theory be reduces to a handful of number describing the intensity and color of the light source, the size and reflectivity of the ball. These numbers are what a JPEG compressor strives to find. Photos of smooth balls are not that common, so the image is split into quite small squares that "locally" is like a section of a close-to-spherical surface. The first approximation is to assume that it is part of a sphere, and determine, from the distribution of tones, the radius and a possible light source. For e.g. cheek sections of a portrait, even the first try may come very close to the input image. In other sections, like around the eyes, lips etc., the compressor must select the most dominant spherical surface, and then add another surface

So he never had his own darkroom? :-) I had, and I am so happy that it has been shelved now. Editing photos on the screen is a thousand times more convenient than the old style darkroom work. Kodak did make a try at instant film and cameras, but they were not very successful in beating Polaroid. Polaroid was The instant camera manufacturer, both before and after Kodak's attempts. There weren't any great selection of chemical processes to choose from for instant photography. For "plain" photography, there were more. If you pick up an old photo album, you may see some of the prints almost completely faded out, while others on the same page have kept up the colors. If you then find the envelopes with all the negatives, you will probably see that the faded ones were printed by one photolab, the good ones by another. Monochrome doesn't fade out to the same degree: The black in the photo isn's a dye, but silver in metallic form. Silver is quite stable. Far better that any dye.

I used to think that but then I found an image handling program with an adjustable quality factor and I no longer do. Many programs, like mspaint, have a fixed quality factor on their exporter and it is set so low that it results in nasty artifacts. With an adjustable QF, I find that a quality factor of 90 to 95% results in an image where I can't see any differences from the original and it still gives an good compression ratio. When I stay with the PNG format too often I get an image with virtually no compression so it is pointless. I definitely see value in keeping images in their original format if you are going to continue to work with it. Successive compressions can compound the loss and it adds up. I do a lot of work with the DDS or DXT format and the loss can be painfully obvious there.

Well, I think he had the start of one, when married my Mum I think those things went away... I also remember a Disc camera from the early 80's, was that Kodak? I wonder how they have faired?
