  • photo query.

    Hi,
    I have a old photo of my uncle taken during his time in the RAF. However the photo only appears to be in detail when viewed in landscape and not in its normal portrait position? Think it's to do with reflection and the silver nitrate but not sure.

    Can anyone please help with how to correct this? Attached is a scan of the same photo in both positions.

    Regards,
    Mike

    Do a search on this site for "silvering" and "double polarized light". This image appears to be the perfect candidate for this technique. Good luck.

      Re: photo query.

      It is not apparent from your images that there is much (if any!) difference between portrait or landscape scan. Of course it may be perceivable in a larger image or an increased scan resolution. There is a degree of uneven fading but it should not present too much of a problem to fix.

      Attached are copies of your scan (with landscape rotated in PS). Curves layer applied plus B&W layer and a small degree of sharpening overall i.e. both images

        Many thanks Mike and Tony,

        Perhaps using a camera with polarized light might correct the problem, but I dont have the means to do. The attached scan on the right looks more detailed to me. I wondered if anything can be done about the grain or would too much detail be lost?

        Regards,

          Re: photo query.

          It is not clear to me that you actually have silvering on this print. Silvering usually takes the form of shadow areas becoming lighter and showing a blue sheen (colour capture) e.g. http://www.cycleback.com/photoguide/silver.jpg

          As to grain and detail it is not easy to comment accurately due to limitations of the posted image.

          The image as provided is only 300x480 pixels so the assumption is that this is only for presentation in this forum.
          Otherwise assuming this was intended for print at a 'reasonable resolution' of 300 ppi you would only get a print of 1" x 1.6"!

          With this image even at moderate zoom JPEG artefacting can be observed this does not help in assessing sharpness.

          So the question would be what size is the original print and what size do you want for the new print?
          Also what were your scanner settings for the original scan, bit depth and resolution?

            Hi Tony,
            The actual size of the print is 120mm x 75mm. The image sent to the site was cut down in size due to the limitations and originally scanned at 2400 dpi. I also have a sacan at 1200 dpi. The machine is a basic HP model with no settings applied.

            Regards,
            Mike.

              Hi Resolute
              I would have to agree with others that I do not see silvering effects on the images. I also agree that what was uploaded is limited due to the pixel size and JPEG compression. Adjustments are much easier if you have a 16 bit version in TIFF format. I suggest sharing the best scan you have or can do through a sharing site (e.g. dropbox, google drive, etc).

              This is the best I could do with an up-sized version of what you posted (using Camera Raw filter and duotone coloring) without also including specific repair processes.

              Nice shot of your uncle BTW

                Ok so the original print (in old money ) measures 4.72" x 2.95" approx.

                Taking your scan @1200 spi gives you an image size in pixels of 5668 x 3542.4. The scan @2400 may be too much with no gains in real resolution

                Printing this 1200 spi scan @300 ppi would give you and image size of 18.9" x 11.8" or at 600 ppi 9.45" x 5.90" approximately

                So you have enough pixels to print a reasonable sized image. By this I mean maybe around 2x original size, say around 10" x 6".

                With all media there is a limit to the scanners ability to resolve real detail - for most print material you may get no real advantage after scanning at the equivalent of 600 spi.

                But scanning at higher rates can/may help in a couple of ways:

                1. Working on the image at a higher magnification may allow you to minimize uneven tones more accurately and when reduced to final output size work may be less noticeable than working on a final sized image.

                2. Any noise may be minimised at the higher mag. using NR software and consequently when resized should become acceptable. I would likely sharpen a little after NR prior to downsizing and again for the final output size.

                Hope this of some help

                  Welcome to RetouchPRO Resolute,
                  Hope you enjoy your stay here and make lots of friends.
                  Poke around, have fun!
                  If you use Photoshop you can post fairly large pictures which are under 100k using the 'save for web' function in Photoshop as described in this thread:
                  (Size, Quality and/or Format your Attached Images..)
                  The save for web function in the latest Photoshop is hidden under File>Export>Save for web (legacy)

                  If you want to post a larger resolution that is over 100K then you can host your image elsewhere and attach a link in the thread, but also, always please attach an under 100K version (so the thread remains useful in the future, regardless of external links). (link to the highest resolution.. or the largest size you can upload)
                  Other Hosts if you do not have your own site: Upload here to your own Gallery
                  Or....one of these among many others:

                    Thanks to all for the input with this. I will look to post a larger sized scan but for the moment this is about the largest one I can send (reduced from 2400 dpi).

                    Sgt Norris Mervyn Harrison RAFVR (age 19).
                    Halifax Air Gunner, killed on operations 25th April 1944.

                        I've done lots of basic photo touching up with photoshop. I'm no professional; my "technique" is scan high, fix what I can without spending too much time. But this time I am really stumped.

It has smoke and soot damage and I would like to scan it before I take it anywhere to have it proffesionally cleaned or restored in case something happens to it there. I read somewhere...

                        Hello,

                        Last week, I retrieve an old oval photo of my great grandparents that dates pre-1918: great grandmother died in 1918. It measures approx. 20.5 inches width by 13.5 inches height, with about 3/4 to 1 inches depth (this measure was taken while photo is lying flat on table; this measure...

                        I am attempting to scan a photo which has irregular shiny areas on the surface. The photo appears normal to the eye when viewed from certain angles, but the trouble areas appear when the photo is scanned or viewed obliquely.
