  • Come on now, those statements are as bad as the OP article :-).
    Ohh, you would not be the author of that article by any chance would you? ;-)

    No deep shadows cannot be saved by underexposure - they are lost/clipped just like overexposure will clip highlights.

  • your experience quite common and to be expected depending on scene DR and your visualisation of the image. And the reason we have so many tools to control the final rendering. However tools will not help if we have failed to capture the required scene range and instead clipped either highlight or...

    Re: "Fogged" Areas of Image

    Assuming you mean lower to mid left of the image the artifacts that you see are in the main the result of physical damage to the print with some fading of paper dyes. Typically incurred by storing prints on top of each other without any protective...

  • Re: Request for assistance with problem restoratio

    I believe the problem you are seeing in this example is uneven light fading. Possibly caused if the slides have been projected as it appears to me; centre faded much more than edges. See attached for original, slightly brightened and...

    Hi OB,
    Interesting comments of which I broadly agree, with just a few reservations, but nothing definitive
    Agreed

  • Re: Request for assistance with problem restoratio

    I agree that it is better practice to get the best at the acquisition stage either camera or scan and minimise the work in post.

    For me to normalise a scan is to correct at the scan stage for any colour, exposure deficiencies,...

  • Re: Request for assistance with problem restoratio

    The reason why a small sample suggested was your OP suggested underexposed with colour cast. As we are looking for channel information (missing or otherwise) even a small JPEG should be sufficient to appreciate the loss of levels and...

    replied to Colour Balance issues
    Re: Colour Balance issues

    It looks like the image is suffering both dark fading and light fading consequently the ROI has lost a lot of the dye that forms the image.

    In addition you may want to consider the state of colour film reproduction at the time the image was shot...

  • Re: Request for assistance with problem restoratio

    At this time just a small section of your scanned image will be fine just to get an idea how bad the 'damage' is. You are limited by the forum limits anyway to 100 Kb for non patron.

    Just add an attachment with a JPEG of...

    If you can post an example (or just a section if size is a problem) of the defective/incorrectly processed film I am sure we will try and help.

    Be aware if the film is truly missing all data in one of the channels a full...

    Re: Text restoration

    If you are editing in Photoshop or similar you could try just working on the red channel.

    With the red channel only selected apply a levels or curves layer and adjust the contrast by moving the black and white points to make the ink darker and the paper...

    Re: Hi-res artifacts

    I doubt that you would loose detail scanning reflective media at 600 spi over 1200. With 1200 you are increasing pixel count and file size but may find that resolution not actually increased.

    You may want to try making two scans and combining in PS....

    replied to what's the diff?
    Re: what's the diff?

    It refers to the Aspect ratio. For instance 35mm is a 3:2 ratio (original) and if you set original to crop when you move the crop box that ratio is maintained. This is not always ideal hence the need for the other ratio choice where you can crop to any desired ...
