    Scanning portra - dealing with highlights

    Hello,

    Scanning Portra and have a bouquet of white roses in the image, in addition to red, yellow, salmon and fascia roses.

    Having trouble getting contrast in the white roses, at least on my monitor. I am using a MacBook Air 11 inch. I understand, not a professional tool, but that's what I am using. When I look at the screen at a very oblique angle, I can see the highlights in the white roses, so I believe the information is there in the film and in the scan.

    Lighting is fluorescent. Shutter speed was such that flicker was not a problem (can't remember the shutter speed).

    Is this a common problem? Do I just post process and upload to Flickr, knowing that the detail is there and will be visible on some monitors?

    Use the eyedropper set to 1 pixel. Go over the rose and read the numbers. Monitors can lie but the numbers won't. If it's 255 in any channel, then it's likely clipped.

    Thanks Peter. There were some 255 readings in my adjusted image. I went back to the raw scan am starting over. The values are in the 190s in the highlight areas in the raw scan.

    Not with drum scanning, no. A good operator can certainly pull detail on a white rose on Portra if it is properly exposed and processed. The "joy" of a drum scanner is that an experienced operator can match the dynamic range of the scanner to the dynamic range of the film (log amps are nice that way).

    Thanks Bruce. I've done some more work and it looks like the Epson color management selections are creating difficulties, for me. I turned off color management and it seems to give the results I am looking for. More work needed.
