Photoshop getting started tutorial (2): temporary disk storage and ruler settings, photoshop getting started tutorial
After creating a document, you can edit the image. Before editing an image, let's take a look at how to view some basic information about the image. In the lower left corner of the software, such information is displayed.
1 window indicates the current image display ratio, and 200% indicates that the current display is magnified by two times. Double-click the left button to modify the display ratio.
2. the space occupied by the current document is displayed in the window. Place the cursor in the figure.Press and hold the left buttonIn the displayed window, the current image information is displayed.
Temporary disk storage settings
By default, Photoshop temporary storage is on drive C, but disk C is limited as a system disk. When processing large files, disk C is insufficient. At the same time, the system response speed will also decrease. So how do I modify the temporary storage?
Menu Bar: Edit -- preferences -- Performance
You must select another disk as a temporary disk to cancel the C disk as a temporary disk, and select a non-system disk as the temporary disk. You can also modify the memory occupied by the software. If you have a good video card, select "use graphics processor" to accelerate the graphics processing speed, especially when rendering 3D layers, of course, the premise is that there is a good professional graphics card. Processing two-dimensional images is ineffective. You can also modify the number of historical steps and cache. Don't forget to click "OK"
Ruler unit settings
When making some large inkjet advertisements and posters, the size is usually measured in meters (m) and centimeters (cm). If pixel (px) is used) unit measurement is inconvenient and difficult to convert. In this case, you need to modify the ruler unit.
1. display the Photoshop ruler first.
Menu Bar: View-ruler (Ctrl + R)
2. Then modify the ruler Unit
Menu Bar: Edit -- preferences -- Performance
In the unit selection box, click the scale drop-down menu and select the desired unit. If you select millimeter, the working area ruler changes accordingly. Click the lower-left corner of the window to view the measurement unit of the ruler.
The above is the basic preparation for image processing. At last, don't forget to save it. When processing images, you must develop a good habit of saving images in a timely manner. Otherwise, in the case of crashes, power outages, and other emergencies, you will be able to give up and regret your failure. You can also set Automatic save.
Menu -- preferences -- File Processing
Modify the Automatic Storage interval in "file storage options. We recommend that you do not set Automatic saving too frequently to affect normal operation. Manually Ctrl + S to save quickly.
Popular Photoshop storage formats
1. PSD (*. PSD)
The PSD format is an image mode generated using Adobe Photoshop, which supports all layers, channels, reference lines, comments, and color modes in Photoshop. When saving an image, if the image contains layers, it is generally saved in the Photoshop format. If you want to save a PSD image with a layer to an image of another format, the layers are merged during the save, that is, the saved image does not have any layers. The PSD format compresses files during storage to reduce disk space usage. However, due to the large amount of image data information contained in the PSD format (layers, channels, editing paths, reference lines, etc ), this is much larger than image files in other formats. However, because the PSD file retains all the original image data information (layers), it is more convenient to modify it. This is an advantage of the PSD format.
2. JPEG (*. JPE; *. JPG)
The full name of JPEG is Joint photographic Experts Group (Joint image Expert Group ). images in this format are usually used in image preview and some Hypertext files (HTML files ). the biggest characteristic of JPEG format is that the file is relatively small. after high-rate compression, it is currently the most compressed format in all formats. however, the JPGE format will lose some data in distortion mode during compression and storage, so the saved image is different from the original image, without the quality of the original image. because it is best not to use this image format for some printed materials.
3. GIF (*. GIF)
The GIF format is a graphic format provided by CompuServe, which is more economical for communication and transmission. It can also use LZW compression to compress files without occupying disk space. Therefore, it is also a compressed format. This format supports the color pattern of bitmap, grayscale, and index color. GIF format can also be widely used in Internet HTML webpage documents, but it can only support 8-bit (256-color) image files.
4. PNG (*. PNG)
PNG is a format developed by Netscape and can be used for network images. However, unlike GIF images, PNG can only store 256 colors (8 bits ), the PNG format can save 24-bit (16.7 million-color) Real-color images, and supports transparent background and the function of eliminating the Sawtooth edge, and can compress and save images without losing the real. However, because the PNG format does not fully support all browsers, and the saved files also greatly affect the download speed, the use of the web page is much less than the GIF format. However, we believe that with the development of the network and the improvement of the Internet transmission speed, the PNG format will be a standard image format used in web pages in the future. PNG files support Alpha channels in RGB and grayscale modes, but not Alpha channels in index color and bitmap modes.
In the days to come, we will learn Photoshop modules. Further understanding of Photoshop's powerful image processing capabilities.
