  1. I would say that the safe option is to do both, produce DVD and also copy to a second hard drive. There is no loss of information in copying digital files using file copy from one system device to another, so make as many copies as you need. Not sure I would want to rely on just a single copy to a DVD if I thought my hard drive was going to fail.

     

    Another option is to get yourself an external USB hard drive enclosure and fit it with a suitably large hard drive instead of using DVDs. The Samsung 400GByte is good value at the moment.

  2. Create the second layer from the drop down layers menu on the toolbar

     

    The box that appears lets you set some of the layer attribytes such as layer name and blending mode etc, but also contains a tick box that says something like

     

    use mask from previous layer

     

    Tick the box and it will associate the mask from the previous layer with the one you are now creating.

  3. Hello Robert

     

    In order to get the registration spot on, I found I had to do all the scans of the same negative one after the other. Most I have ever done is 3, but find 2 is usually fine. If the exposure differences are too great, then the blending starts to look false although that will depend on the subject matter. I also use manual focus and only set the focus for the first scan, that might also make a slight difference.

  4. I posted this in the thread below, but also here in case anyone does not read lower down

     

    After trying some of the suggestions here and in the other thread, I failed to make it work. So did some experimenting of my own and found a solution.

     

    You need to set in

     

    edit/preferences/memory and image cache

     

    cache level to 1

     

    Close and reload PS

     

    The problem might be related to the use of real memory because the higher the cache level, the more memory is used.

     

    Anyway - worked for me, post in the SmartSharpen thread below if it helps

    The 5400 can produce acceptable negative scans for the most of your negatives. There will always be a few difficult ones where you have to resort to using linear and converting yourself but let the scanner do the bulk of the work

     

    Try this simple workflow for your negatives

     

    Turn off colour matching

     

    Use 16-bit negative settings

     

    Use the pointer and RGB display in the exposure tab to ensure greys/whites do not have a colour cast

     

    Use the exposure tab to adjust exposure to ensure there is no important clipping

    Do not make changes using the other editing controls

     

     

    When you open the image for editing, assign the negative profile Minolta 5400 Nega Input and convert to you favourite colour working space.

     

     

    If having got the exposure right, you have blown highlights, then you will have to make a second exposure for just the highlights (or shadows) and blend the 2 scans. A quick way to do this on a PC is to paste the highlight image over the base one

     

    CNTRL SHIFT ALT tilda to select the highlights on the top image

     

    Click add vector mask in the layers palette

     

    Select the mask and run Guasian blur 15 to 30 pixels on the mask to avoid hard transitions.

     

    Paint on the mask for any other detail of interest

     

    Thats it blended

  7. Robert I find what you are doing a bit of a mystery. Lets just take a look at that. Assuming you are scanning slides in linear

     

    The scanner produces its output (internal) in the posi-linear workspace. You make the scanner convert that to WideGamutRGB for output

     

    You read the file into PS and convert from WideGamutRGB back to posi-linear and then assign (I think you mean convert!) to BestRGB. That is a lot of colour space conversions.

     

    Turn off colour matching in the scanner software and it will create an output file in the posi-linear workspace. You then assign the posi-linear profile when you open the image and convert to your workspace (BestRGB) � that equals one colour space conversion

  8. I should have added that the advantage of keeping the scanned image in the scanners native colour space/profile is that you do not degrade it by converting it to another colour space. For example, had you scanned all your images as AdobeRGB or sRGB and now decided to use ProphotoRGB, those scans would have to be redone because you have lost the colour information. Had you scanned them to the native scanner work space, then its just a different conversion on opening the image.

     

    Hope that helps

  9. Michele - I use a Minolta scanner so am not familiar with the Nikon, but they probably work in a similar way for colour management.

     

    Looking at the options displayed, I assume that ScannerRGB is the Nikon profile for the scanner and gives the best the scanner can generate. So select that (ScannerRGB) and when you open the image in Photoshop assign ScannerRGB to it (if the file was not tagged) and then convert to your work space eg ProphotoRGB or Ectaspace - can do all that in the open dialogue if you set the colour preferences that way.

     

    Alternatively, scan with Nikon colour management turned off and assign the relevant positive or negative scanner profile when opening the file in photoshop, then convert to the colour space. Its all done on opening the file. That is what I do with the Minolta 5400 and seems to give me my best results.

  10. An interesting question but you are assuming that colour spaces and output printer profiles all neatly fit within each other. What you will find is that bits of the printer space are outside the area covered by some profiles even though the colour space might have a larger volume than the printer. So if use a working colour space that does not include ALL parts of the output space, you will not be able to faithfully reproduce some colours contained in your image. Quite often it is not an issue for some images.
  11. ImageMagick provides a set of command line tools and interfaces that let you use it from Windows command prompt.

     

    The command line utility you want is called CONVERT and is installed along with all the other ImageMagick components. You can set up a simple .BAT file to execute it if you want to do it repeatedly. The -filter type is where you specify Lanczos as the method to be used.
