The Photoshop and illusions.hu flavors also produce the same result when the top layer is pure white (the differences between these two are in how one interpolates between these 3 results). These three results coincide with gamma correction of the bottom layer with γ=2 (for top black), unchanged bottom layer (or, what is the same, γ=1; for ...
Gradients of RGB intermediate colors (orange, lime green, sea green, sky blue, violet, and fuchsia), and a full hue spectrum are also present. Color charts are not gamma corrected. These elements illustrate the color depth and distribution of the colors of any given palette, and the sample image indicates how the color selection of such ...
A linear, or axial, color gradient. In color science, a color gradient (also known as a color ramp or a color progression) specifies a range of position-dependent colors, usually used to fill a region. In assigning colors to a set of values, a gradient is a continuous colormap, a type of color scheme.
The following depth map of a shark with smooth gradient produces a perfectly readable autostereogram, even though the 2D image contains small monotonic areas; the brain is able to recognize these small gaps and fill in the blanks (illusory contours). While intelligible, repeated patterns are used instead of random dots, this type of ...
I've made some edits to the photo. Ran it through auto contrast/level/colour in Photoshop and rotated it 0.5 degrees clockwise. Enochlau 13:10, 17 December 2005 (UTC) Oppose. The sky looks great, but it dominates the image and places much of the stand in shadow. Warofdreams talk 18:02, 19 December 2005 (UTC) Oppose. The stands are too dark, and ...
Vignetting is generally regarded as true light fall-off due to physical phenomena (eg obstruction of lens, etc) though, not a darkening of the image periphery in photoshop. I know the end-product is basically the same visually, but I think a real-world example of vignetting is more appropriate for the article than a synthesis.
"Overlaying" or folding or hammering on gold foil or gold leaf is the simplest and most ancient method, and is mentioned in Homer's Odyssey [8] and the Old Testament. The Ram in a Thicket (2600–2400 BC) from Ur describes this technique used on wood, with a thin layer of bitumen underneath to help adhesion.
The images must be free for any purpose, commercial or otherwise, by any person, in any medium, and at any size. -- Gmaxwell 00:14, 20 June 2006 (UTC) [ reply ] Right on all counts except the size - rather, you forgot a detail: the photo will be never be any 'bigger', in any good quality, than the size it is published.
