So there are pragmatic reasons to produce greyscale output from a colour file. Any later adjustment, retouch, spotting etc can then apply to all versions automatically. This means that one does not need to commit irreversibly to a particular greyscale conversion, and that the single file can be used for (maybe several) colour versions plus maybe a series of greyscale options, depending on the layer comp. This can be printed from directly (or a one-shot TIFF made for print resampling) but it arises from a colour RGB master. One practical issue, for those working in (e.g.) Photoshop: greyscale conversion from colour is often done with an adjustment layer approach (and there are a number of ways to do this) resulting in a monotone or colour tinted tone RGB output. The photograph isolates and perpetuates a moment of time: an important and revealing moment, or an unimportant and meaningless one, depending upon the photographer's understanding of his subject and mastery of his process. On that basis, provided you get the right information into your image file, Greyscale should produce the fundamental basis for then going on to produce top quality B+W prints. I use PhotoShop only to replicate, basically, what I would have done in a conventional darkroom and have found conventional B+W workers, who know what they want in a wet darkroom are more likely to be able to produce equally excellent digital prints. That converted into same for digital printing, meaning my quality standards have remained as high as before. There are lots of conflicting methods, some very muddled, others seemingly superior.Īll I can say is I had a respected reputation for producing the highest quality darkroom prints and ran workshops for same for those wanting to produce high quality for many years. after a lot of tests (meaning making prints) I found the brightness values of the scene in colour are best recaptured tonally using the Greyscale conversion method. If your documents keep opening in grayscale mode, go to File>New and make sure color mode is set to RGB or CMYK in the new document dialog box.Ĭheck out The Reason Photoshop Keeps Changing Your Colors. To get back to a standard color mode, click Image>Mode and select RGB or CMYK. The photoshop image appears in black and white because it’s on grayscale mode. It is useful for specialized printing.įind out more on color modes from adobe. Multichannel mode has 256 levels of gray for each color channel. The numeric values in Lab describe all the colors a person with normal vision sees. Lab color mode is based on the human perception of color. Images are formed through the interaction of Red, Green and Blue light to display up to 16 million colors.ĬMYK is the mode for images intended for print where colors are combined using four inks Cyan, Magenta, Yellow and Key (black). RGB is the color mode that’s used primarily for images intended for screen displays. I ndexed Color mode produces 8‑bit images with up to 256 colors. Black and white images look better on grayscale mode than color as the contrast is improved.ĭuotone Mode is used for turning your black and white image into an image with 2, 3, or 4 colors. Grayscale mode is used when editing an image that’s already in black and white, such as a drawing or painting. The color modes in Photoshopīitmap mode uses either black or white to define the pixels in an image. Grayscale may also be used on color images that have been converted to black and white using a third-party software or by the camera itself (typically for printing purposes). Grayscale is most often used to display black and white photographic images, artworks and line art. Grayscale Mode: Grayscale mode displays images with a monochromatic or single-color palate of gray scales based on the level of lightness (from black to white). If all your documents keep opening in grayscale mode, go to File>New… and in the new document options, make sure color mode is set to RGB or CMYK and not grayscale.
