Photoshop can be said to be the most popular image processing software now. Photoshop is not large in itself, but it requires a high amount of memory when processing images, usually more than five times times the size of the currently processed graphics file. Looking at such a good software, in their own computer on the hard work, they can not help but ask a "is there really no way?", the computer Theme House (www.51ztzj.com) tells you that as long as we have a reasonable setting of Photoshop's operating environment, we should pay attention to some skills in operation, can get faster image processing speed.
The first thing to understand is that Photoshop is running with the image data stored in memory, scratch disk (Photoshop on the hard disk in a dedicated virtual memory space) and operating system virtual memory, when the memory is not enough to use both, but the processing speed will be greatly reduced. Looking at the efficiency status shown at the bottom left of the Photoshop screen, if its value is below 100%, indicating that there is not enough memory, Photoshop is already using the scratch disk, then optimization is necessary to ensure that Photoshop runs fast.
The key to improve Photoshop image processing speed is to let Photoshop only use memory to store image data, avoid using low speed hard disk virtual memory, there are two ways to achieve: first, adjust the system settings, improve the amount of memory available to Photoshop; the second is to use reasonable operation method, Reduce the amount of memory that Photoshop needs to run.
First, adjust the system settings:
1. Increase the amount of memory available in Photoshop The amount of RAM available to Photoshop is determined by the model, and if the system is equipped with higher memory, you can allocate more memory to Photoshop in the Finder; in Windows, The default amount of memory available for Photoshop is 75% of the current system availability, and if your PC has more than 32M of RAM, you can increase the ratio of "parameter settings" in Photoshop. To do this: Open the Potoshop software and select the memory&image Cache option in the Preferences drop-down menu under the "File" menu. Increases the proportion in the Used by Photo-shop item in the dialog box. When you are done adjusting, click OK to return.
2. Set a large enough scratch disk regardless of whether Photoshop is using the scratch disk, the free space of the scratch disk must be greater than the amount of memory available to Photoshop. The reason is that Photoshop writes the contents of the entire memory to the scratch disk while it is waiting, and if the free space of the scratch disk is less than the available memory, Photoshop will automatically reduce the amount of memory used. For example, if Photoshop has 60M of memory available, and the scratch disk has only 40M free space, 20M of memory will be idle. By default, Photoshop takes the boot disk as the scratch disk, and the user should have the fastest, most free space, and the least fragmented disk as the scratch disk. To do this: Open the Potoshop software and select the memory&image Cache option in the Preferences drop-down menu under the "File" menu. Change the setting in the/plug-ins&scratch Disk item in the dialog box. For friends who often deal with large graphs, it is a good idea to have a separate partition above 300M as a dedicated scratch disk for Photoshop.
3. Upgrade Photoshop version This is not to do more introduction, the higher the better.
4. Use memory compression software if there is a high-speed Pentium core, but not enough memory, in the processing of large graphics, the use of memory compression software is an effective way to improve speed. Although memory compression consumes CPU time, it is still much faster than using a scratch disk.
Second, reduce the application requirements:
1. reduce file size
Method One: Set the appropriate resolution and size for the graphic. Usually the default resolution of the Photoshop file is high, before processing the Photoshop file, you should set the resolution and size of the graphics according to the output requirement, so as to avoid high resolution editing low-resolution output.
Method Two: Edit the color graph using RGB display mode. If you are making a file to color separations, you should first edit in RGB mode, output before converting to CMYK mode, because the size of RGB files only CMYK 75% size.
2. Using image caching Photoshop You can use image caching to speed up the redraw of high-resolution images. To do this: Open the Potoshop software, select the Image Cache (Macintosh) in the "Preferences" drop-down menu under the "File" menu, or select the "in the Preferences" drop-down menu under the "File" menu. Memory&image cache (Windows) option to change the size of the buffer, enter a valid value between 1~8, the larger the number, the faster the screen redraw, but the cache occupies more memory, if the system has sufficient memory, should be set to the maximum. To increase the speed at which histogram graphs are displayed, you should set the use of the cache display histogram diagram in the preceding options, but with a slightly lower precision.
3. Erase unused data in memory remove graphics and selection blocks that are saved on the Clipboard, defined patterns, and snapshots occupy memory, and clear the contents to increase the amount of available storage for Photoshop. To open the Photoshop software and select "Purge" under the "Edit" menu, use Undo to remove the memory occupied by the previous operation data.
4. Free some irrelevant memory examination large forums use "Clipboard" to release the memory of the Clipboard contents, using "pattern" or "Snapshot" to release any patterns or snapshots occupied by memory. In addition, merging layers that are no longer needed and deleting unused "channel" can increase the amount of available memory for Photoshop.
5. Use less memory-intensive routine operations
A: When you transfer and copy data, you should use drag-and-drop, less use of the Clipboard.
B: Turn off the pre-view function of the Panel menu.
C: Use the selection block reasonably. Saving the selected block in channel, or making a complex selection block of color files with grayscale files, can reduce memory footprint and save processing time. When working in a bitmap diagram, it can be faster to save the selected block as a path.
D: Use two working windows. A display of local amplification graphics, another display of the entire graphics, can greatly reduce the window zoom operation, improve operating speed, but also to compare and observe the composite Channel school color and single channel color difference.
6. Use a less memory-intensive approach
A: Use a filter in a single channel. Some photoshop filters, such as warp filters, can only be performed in memory, not scratch disks. Filters can be used in each individual channel if there is not enough memory to perform. In RGB file, each channel only one-third file size, and in CMYK file, only One-fourth size.
B: Use Quick edit. A quick edit can edit only a portion of a file, so it can significantly increase the opening speed of a file larger than 4MB. When the memory is not enough, fast editing is also an effective way to complete the large image processing. Fast editing can greatly improve processing speed when experimenting with different shading or filter effects.
C: Use a low-resolution version to try the color correction parameters. For example, in the color of the graphics, you need to try a number of school color parameters to find the best value, if directly in a high-resolution large image to try different parameters, it will take a long time. At this point you can copy a low-resolution version, quickly find the best parameter values, and then the original school color can be one-step.
