Re: Inverting Tones in a B and W image

Marv, You can always convert a 16 bit Black and white image to a 48 bit colour image without degredation of quality. The colour image just takes 3 times the space im memory, in a 16 bit BW image every pixel is represented as just one value, in a 48 bit image with 3 identical values for R, G and B. I...

Re: How to crop

Chris, I do such tasks like this: First I crop to the size visible by the passe-partout, 13 x 8.6 in your case, with a 1 to 2 mm oversize, depending on the size of the image and the quality and tolerances of the frame and passe-partout. From now on it can go in a workflow: I resize the image to the ...

Re: Layout Transform

Marv, But you can only compare the quality if you know what method is used by Layout. If your specific image rescaled to your specific size has a (visible) better quality using a resampling method other then bilinear you should probably resize in an extra step. Expanding the range on a absolute diff...

Re: Layout Transform

Jonathan, what resampling method is used in Layout ?

Marv, if you want to compare the resizing in Layout with Resize you should use the same resampling-method in both cases.
If different methods are used in Layout and Resize minor differences would be normal.

Re: DL-C.COM Maintenance

Jonathan,

The website looks ok now, but I didn't do any further testing.
The link to DoF works fine, I downloaded and installed the latest version yesterday morning.

Re: Clever idea for scanning film

Mark, I have used a pair of rulers put on the borders of the negatives to keep them flat.
I have used steel rulers, but if it isn't too light everything straight will do.

Re: Clever idea for scanning film

Very nice idea, thanks for sharing. I did something similar with medium format negatives my mother has from way back time. My film scanner is not capable of processing medium format, so I took a white sheet of paper, illuminated it with 2 halogen spots, put a glass plate above it and put the negativ...
