pretvaranje u rgb ima i u foto manager-u. onda bih mogla tamo da probam. vidis to mi nije palo na pamet. nego, sad na toj fotografiji koju si umanjila, ima pixela koji su u zelenoj boji, bar ih ja tako vidim. na tvom Lidija, avataru takodje vidim neke tackice nepravilnog rasporeda...zasto se to desava? |

Indexed Color mode Indexed Color mode produces 8‑bit image files with at most 256 colors. When converting to indexed color, Photoshop builds a color lookup table (CLUT), which stores and indexes the colors in the image. If a color in the original image does not appear in the table, the program chooses the closest one or uses dithering to simulate the color using available colors. Because the palette of colors is limited, indexed color can reduce file size yet maintain the visual quality needed for multimedia presentations, web pages, and the like. Limited editing is available in this mode. For extensive editing, you should convert temporarily to RGB mode. Indexed color files can be saved in Photoshop, BMP, GIF, Photoshop EPS, Large Document Format (PSB), PCX, Photoshop PDF, Photoshop Raw, Photoshop 2.0, PICT, PNG, Targa, or TIFF formats. |

RGB Color mode Photoshop’s RGB Color mode uses the RGB model, assigning an intensity value to each pixel. In 8‑bits-per-channel images, the intensity values range from 0 (black) to 255 (white) for each of the RGB (red, green, blue) components in a color image. For example, a bright red color might have an R value of 246, a G value of 20, and a B value of 50. When the values of all three components are equal, the result is a shade of neutral gray. When the values of all components are 255, the result is pure white; when the values are 0, pure black. RGB images use three colors, or channels, to reproduce colors on-screen. In 8‑bits-per-channel images, the three channels translate to 24 (8 bits x 3 channels) bits of color information per pixel. With 24‑bit images, up to 16.7 million colors can be reproduced. With 48‑bit (16‑bits-per-channel) and 96‑bit (32‑bits-per-channel) images, even more colors can be reproduced. In addition to being the default mode for new Photoshop images, the RGB model is used by computer monitors to display colors. This means that when working in color modes other than RGB, such as CMYK, Photoshop interpolates the CMYK image to RGB for display on-screen. Although RGB is a standard color model, the exact range of colors represented can vary, depending on the application or display device. Photoshop’s RGB Color mode varies according to the working space setting that you specify in the Color Settings dialog box. Note: ImageReady uses only the RGB mode to work with images |

... hm, a da napravimo neki mali priručnik za PS? Npr. sliku smanjiti sa: 1. 2. 3. i tako to. Ja ne radim u njemu, ali vidim da mi nema leba... pa da uz korake lakše taj lebac umesim! |
