Photoshop Getting Started Tutorial (ii): Scratch disk settings and ruler settings

After you create a new document, you can edit the image. Before you edit the image, let's look at some basic information about how to view the image. In the lower left corner of the software, there will be such information displayed in the window.

The 1 window represents the current image display scale, and 200% represents the current magnification of twice times the display. Left-click to modify the display scale.

2 window displays the space occupied by the current document, the mouse is placed in the icon position, Press and hold the left button , the 3 window appears, displaying the current image information.

Scratch disk Settings

Photoshop Scratch Disk By default is in the C drive, but the C disk as the system disk space is limited, when processing large documents, C disk space will not be enough. At the same time, the system response speed will also decrease. So how do I modify a scratch disk?

Menu bar: Edit-Preferences-performance

To uncheck the other disk as a temporary disk to cancel the C disk as a temporary disk, select non-system disk as scratch disks. At the same time can also modify the memory of the software, if there is a good graphics card, tick "Use graphics processor" to speed up the graphics processing speed, especially when rendering three-dimensional layer of the effect is obvious, of course, the premise is a good professional graphics card. When dealing with two-dimensional images, the effect is small. You can also modify the number of steps for history and the cache. Finally, don't forget to click "OK"

Ruler Unit Settings

When making some large-scale inkjet ads, posters, the size is usually in meters (m), centimeters (cm) units, if measured in pixels (px) is very inconvenient and bad conversion. In this case, you need to modify the ruler units.

1. First display the Photoshop ruler.

Menu bar: View--ruler (Ctrl+r)

2. Then modify the ruler units

Menu bar: Edit-Preferences-performance

In the "Units" box, click the Ruler drop-down menu and select the desired unit. If you select millimeters, the work area ruler will change accordingly, click on the lower left corner of the window to see the ruler unit of measure at this time.

The above as image processing of the preparatory work is basically ready to complete, and finally, do not forget to save. In the processing of images to develop a good habit of timely preservation, otherwise encountered in the crash, power outages and other unexpected situations, naught, regret. Of course, you can also set auto-save.

Menu--Preferences--File processing

In the "File storage Options", modify the auto-save interval. It is recommended that you do not set auto-save too frequently and affect normal operation. Manual Ctrl+s Quick Save.

Photoshop Common storage format popular

1.PSD (*. PSD)

The PSD format is an image pattern generated using the Adobe Photoshop Software, which supports the formatting of all layers, channels, guides, annotations, and color patterns in Photoshop. When you save an image, it is generally saved in Photoshop (PDS) format if the image contains layers. To save a PSD format image with a layer to an image in another format, the layer is merged when it is saved, that is, the saved image will not have any layers. The PSD format compresses files to reduce disk space while saving, but because the PSD format contains more image data information (layers, channels, clipping paths, guides, etc.), it is much larger than other format image files. However, because the PSD file retains all the original image data information (layer), it is more convenient to modify, which is the advantage of PSD format.

2.JPEG (*. jpe;*. JPG)

The full English name of JPEG is Joint Photographic Experts Group (joint image expert team). Images in this format are typically used for image previews and some hypertext documents (HTML documents). The most important feature of JPEG format is the small size of the file. After high-rate compression, is the highest compression rate in all formats. However, the JPGE format loses some of the data in the process of compressing and storing, so the saved image differs from the original. The quality of the original image is not good. It is best not to use this image format for some printed matter.

3.GIF (*. GIF)

The GIF format is a graphic format provided by the CompuServe, which is more economical in communication transmission. It can also use LZW compression to compress files without taking up too much disk space, and is therefore a compressed format. This format supports color patterns for bitmap, grayscale, and indexed colors. GIF format can also be widely used in Internet HTML Web documents, but it can only support 8-bit (256-color) image files.

4.PNG (*. PNG)

PNG format is a format developed by Netscape Company, can be used for network images, but it is different from GIF format image can only save 256 colors (8 bits), PNG format can save 24 bit (16.7 million color) True color image, and support transparent background and anti-aliasing edge function, You can compress the saved image without distortion. However, because the PNG format does not fully support all the browser, and the saved files are larger and affect the download speed, so the use of the Web page is much less than the GIF format. But it is believed that with the development of Internet and the improvement of Internet transmission speed, PNG format will be a standard image format used in future Web pages. PNG format files support alpha channels in RGB and grayscale mode, but alpha channels are not supported in indexed color and bitmap mode.
