I post-scan-processed “long road home”. This part is mechanical, just adjusting to bring out the best possible image. But the visual reward – to have truly printable high quality images – just the impact of that many pixels is incredible. The original canvas is 30″ x 40″.
This image links to the reasonable-sized detail image – the blue outline is the section that the detail image captured – the detail image links to a full size image of the section – you will have to scroll around to close it, it is larger than the resolution of most monitors (the image size is roughly 1200 pixels x 2200 pixels). It does give you a sense of what a 44 MB jpeg image can capture – distilled from a 618 MB TIFF file.
This was not sharpened except at the noise reduction filter level, and that only slightly. To print effectively it is likely to require more sharpening. There is a technique called high pass filter sharpening , which failed miserably in this case, but was outstandingly effective on “weathervane”. On this painting image, it turned the colors toward shades of grey, and I went back and started over again.
High Pass Noise Filtering (Photoshop CS2)
On the Layer palette select your Background Layer and right click. Select Duplicate Layer.
- With this new layer highlighted select Filter / Other / High Pass. Set the Radius to 10 and click OK.
- Zoom into your image to Actual Pixels level so you can better see what you’re going to do next.
- Go back to the Layer Palette and select Hard Light from the left drop down.
- Now go to the Opacity Slider and select a level of sharpening that seems best to you. Usually something between 20% and 70% will be best.
