Not all browsers show images in the same way. I am working on a Mac G4 PowerBook. Safari occasionally produces a more strongly saturated and contrasted image than Firefox. Where I’ve let Firefox show
an image too blandly, downloading it and opening it from the desktop
seems to solve the problem. If I compensated for the blandness, the downloaded version will look over-contrasted. Maybe I should optimise for Safari, which reads the original file more accurately.
But there is no way of knowing how those images
will look on a different computer. Results on some screens are just going to look terrible and there’s nothing you can do about it (black and white images are as treacherous as colour).
And the way we edit in the first place is probably governed by our, not the artist’s, idea of colour. We’re used to acrylic paint and strong light, colours used to sell consumer products, backlit screens. They have cheered life up, but the relations between colours were subtler a century ago. We’re dealing in works of art with colours that may, anyway, have faded.
I need to reread Tanizaki’s wonderful, reactionary In Praise of Shadows.
