April Meeting Information
The April Photoshop SIG meeting will be held on Thursday, April 10th, from 6:30 to 8:30pm at Voorhees High School in room 245. April’s meeting will look at the automated features within Photoshop for creating contact sheets, picture packages, and a web photo gallery. Additionally, Walter Chandoha will share some of his experiences with the Raw image format. Members are encouraged to bring in their images for discussion during the question-and-answer session.
Photoshop Upgrades
The recently released 15.2MB Photoshop 7.0.1 download will be available at the meeting for members with slow internet connections. If you would like a copy of the updater, please bring a 100MB Zip disk to the meeting. This update requires version 7.0 and fixes a number of problems discovered after it was released. There have also been a number of minor updates released for Photoshop 7 which are small and easily downloaded from any speed internet connection. The Mac OS X Keyboard Shortcut Fix, 7.0.x File Browser Update, the 7.0.x AltiVecCore Update plug-in, and the ContactSheetII plug-in update are all under 230KB, and can be downloaded at http://www.adobe.com/support/downloads/ in the Photoshop/Macintosh section.
Desktop Printing: Rendering Intent
Anyone who has delved into their desktop printer’s settings may have seen an option called “Rendering Intent.” Generally speaking, this option translates the colors of an image to the color gamut of a destination device. Depending on the final printed output you want to achieve, when selecting your printing settings, you should choose the rendering intent using the following guidelines:
Saturation maps fully saturated colors in the source to fully-saturated colors in the destination, even if the hues change. It will generate a vivid output. It is suitable for business graphics, but not recommended for color matching.
Perceptual (sometimes called Image, or Photographic) tries to compress the gamut of the source space into the gamut of the destination space in such a way that overall color relationships are preserved, even though the colors in the image may be changed in the process. Use this for getting the most pleasing final output from your original RGB image. It is suitable for photographic content.
Absolute Colormetric reproduces those colors the target device can reproduce exactly, and clips the non-reproducible colors to their nearest reproducible hue, sacrificing lightness and saturation. Use this rendering intent for reproducing spot colors, and press proofing but when you want to simulate the color of the paper on the proof.
Relative Colormetric works the same way as Absolute, except that it scales the white of the source to the white of the target. It provides maximum color accuracy and is suitable for proofing with CMYK input. Use this rendering intent for proofing when simulating the paper color is not critical.
Tips and Tricks
Copying a Layer into the Exact Same Spot in a Different Image
If you want to make a copy of a layer, and have it in the same position in a new document, just Control-click on the layer in the layers palette and choose “Duplicate Layer.” When the dialog comes up, under “destination,” select the name of the file you want to copy the layer into.
