Photoshop open 10 things



Adobe Photoshop is the most popular one of graphic design software. It can be said, as long as you touch graphic design, then no matter sooner or later, you have to deal with it. About Photoshop, say it is too much, but whether you want it to be your right-hand man, or just use it for some of the most basic image processing, then the following are 10 things you must know , whether you are a beginner or already have some knowledge about it.

1. Shortcut keys to use: This is the basis of the basic Photoshop, it is also the best way to improve work efficiency. The use of shortcuts, so you can better focus energy on your work rather than the tool panel. Once you are able to skillfully use the shortcut keys, you can use the full screen of work, save the unnecessary panels, and make the vision more open, maximize the use of screen space; some simple commands can use the keyboard to complete, not choice of the tool distraction, even if it only takes up very little time, but we hope not to be interrupted at work.

Note: You should use the shortcut keys as much as possible, following these shortcuts is to improve the efficiency of a good helper, but I do not know why so many books are passed over, not even mentioned, be sure to keep in mind.

Ctrl + J: Copy the current layer to a new level;

J: Switch to the spray gun tool;

M: Switch to the Marquee tool;

[]: Tools for the pen in the current mode (including the spray gun, brush, pencil, brush and imitation stamp history, such as rubber and fuzzy tools and deepen), followed by written change in size;

Shift + BackSpace: Fill in the dialog transferred out.

The beginning, you may not remember all the shortcut keys, you can use Photoshop's tool tips to help you. Is to open the Edit> Preferences> General, select "Show tool tips." In this way, when you move the mouse to tool panel, the tool name and its shortcut will appear, until you remove the mouse will disappear.

2. Seamless Texture: both for the production of 3D images or pages, seamless texture is very important, we can easily be completed in Photoshop. Good for your custom images, run Filter> Other> displacement, in the horizontal and vertical displacement, the general displacement of the image size set to half of the most important thing is to set back and defined area. After the completion of displacement, with a rubber stamp tool to smear the image of the mosaic Department, to eliminate seams, then the image is defined as the pattern. Filled with this pattern, you can get seamless background image.

3. A combination of commands for commonly used custom action: when dealing with images Hou, in many cases we will use combination of command. For example, the image needs to be a multi-document to another document. The most efficient and secure method: New layer Shift + CTRL + N; put together all of the following visible layer Shift + Alt + CTRL + E; select all the images Ctrl + A; Copy CTRL + C; Deselect Ctrl + D; delete the current layer. This set of commands is for the images to establish a mapping that contains the current layer of all visible layers under the image, then you have already left the clipboard image content, so long as it is pasted on the document needed Ke Yi the. This is a very typical example, although you can use a series of shortcut keys to complete this set of commands, but it is recommended to save it as an action, the action options panel, you can set for this action a convenient function keys such as the Shift + F2, so that you always call, very convenient, especially the images from Photoshop into other applications at the right time save considerable time! Shift, Control, and F2 to F12 of these different combinations, you can define a lot of movement, greatly improving efficiency.

4. Automatically selected layers: a little trick quite modest, but is also used, especially in multi-layers of large files, even sticking to the command for each layer, according to the order of stacked layers, the choice is more problematic - you might not remember which layer they belong to, the consequences of the wrong operation is sometimes terrible. At this time, you can first select the move tool, the tool options check the "Auto select layer", so, in addition to slicing tool, the path component selection tool, Pen tool and starting point for tools, other tools in the toolbox for the current selection, hold down the Ctrl key while the current tools are being turned into mobile tools, click on any object on the canvas, Photoshop will automatically go to it in layers, so that you can operate the. In the current mobile tool, even if not chosen automatically select the layer, hold down the Ctrl key as long as the same freedom of choice can belong to different layers of the image content.

5. To create a custom brush: In Photoshop, there is a very useful but not fully utilize the resources of most people, that is to create a custom brush. Create a new document produced by brush size to the size of black (or a different color or grayscale, but this system out of the brush lighter color) Draw your brush image, such as a flower, How many pieces of small tree and so on. Then use the Rectangular Marquee selection, defined as a new brush. If there is no choice, then Photoshop will define all the images on the canvas brush. In this way, you can use a custom brush creation of these unique images of all kinds, especially the border and other decorative designs.

6. Lens flare effect: in the primary image processing, lens flare can be said that one of the most common modification effect. In general, you can use the filter in the image> render> lens flare, to increase the atmosphere of the image. So, if you are a time lens flare effect is very satisfied with the hope that it preserved, we can use the mixed layer properties. Advance in the image on the new layer, fill with black, and then implementation of the lens flare filter, then a layer of this hybrid model layer is set to "screen", so that the black was faded, you will get a separate flare layer effect. However, this is the only drawback is that the image can not be displayed in white.

7. Lighting effects filter: This filter gives the biggest surprise is that it can create a variety of realistic texture. The simplest usage is: place texture to a simple one channel, and then apply a layer of filter> render> lighting effects, texture channel selection in the store just the texture of the channel, adjust light settings corresponding This will be a three-dimensional texture effect.

8. Using adjustment layers: No one can grasp an image adjustment will be very imperfect, and therefore, in addition to develop good backup habits, the best time to use adjustment layers to make use of adjustment layers Hou. You may find trouble, but this trouble and loss of damage to the image comparison are minimal. And more importantly, you can at any time in the creative process to make new adjustments to the image without worrying about damage.

9. Fast replication techniques: in the same document, determine the current mobile tools (or temporarily move the tool), press the Alt key while dragging the object, you can copy, hold down the Shift key, can guarantee by 45 degrees angle of multiple mobile; between different documents, hold down the Shift key when moving, if two documents are the same size, then the object to the new location of the same document, if the document sizes, then the object is copied to the new document center. Copy this way, not only convenient, but also can reduce the use of the clipboard, to further save system resources.

10. The accumulation of the results: When you use Photoshop for some time, will save a lot of good stuff down. If you painstakingly prepared the gradient, contour, pattern, etc., but also facilitate the work of some other color palette. These are just temporarily stored in Photoshop's, when heavy equipment, Photoshop will be restored to the default state, so clean Yo, these custom stuff will disappear without a trace. This is not only unfortunate, it will also impact your work (as defined palette is missing). Therefore, the best time for every editing software to use the default manager Hou preserved, stored in a special folder. Preset Manager can save the brush, palette, gradients, styles, patterns, contours, custom shapes, such as your work will not be lost. After reloading, cover with the corresponding documents can return to a familiar work environment.

Microfilm only by a small amount of space occupied, and the traditional paper medical records take up a lot of space and maintenance costs compared to a year savings for the hospitals is considerable.

Paperless storage remarkable results

1. Save the human, financial, and material costs

251 patients discharged from hospitals each year about 4 million people, such as paper storage requires a lot of paper medical records need to purchase the aircraft and increasing medical records storage room. From the full implementation of electronic medical records storage, the part of each paper medical records an average reduction of about 30 sheets A4 paper, 90 by discharge / day per day for hospital medical records of only one can save paper and nearly 3000. From 2007, the implementation of paperless electronic medical records storage, more than two years our hospital has saved more than 1 million yuan print consumption. Because a lot of space occupied by Medical Records Storage and maintenance costs are substantial, the direct annual cost savings of up to 150 million yuan.

2. Optimize the case management functions

In the past, medical record room staff mainly engaged in paper-based medical record for finishing, binding, shelving and other complicated work, part of the medical records in question may be in the hands of more than 5 times can be filed. At present, the medical record room staff just finishing some small amount of paper, and the rest you can check in online, so that medical records from a single medical record room staff in order to work gradually freed to focus on the inner of Medical Records quality of management, the number of personnel is also reduced from the previous 5 to the present two.

3. To reduce the nursing workload of office clerks

Take care and office clerks original order by a doctor after another in the medical process of medical instruments, printing or writing, the patient's informed consent, inspection, test departments gradually returned to the report card, the nursing process gradually produced a single medical advice, treatment orders, vital signs sheets, etc., work load significantly, and prone to error.

4. To ensure that medical records storage media and information security

Paper medical record not only needs some storage space, and medical records kept in kind, there are some security risks, such as fire, moisture, mildew and so on. Electronic Medical Records Storage Medical Records can be backed up after the entities have fundamental change, making it possible to be preserved; on the other hand also enhanced the security of medical record information to prevent information leakage, tampering and theft.

5. Improve the discharge rate of medical record three-day archive

Medical staff on the medical history will not repeat printing, thus reducing the discharge of medical record filing procedures, so that hospital medical record filing rate over the previous three days had significantly improved. Before and after implementation compared with the same three-day hospital medical record filing rate from 86.97% to 96.66% increase and improve range of measures than any obvious.

The basic conditions for paperless storage

1. Integrity

A variety of development tools known medical history can not be the same time the text, images, tests, electrophysiology, etc. can come together and solve the medical records data integrity issues. The patient's medical records are records, including the following four parts: First, hand-written medical personnel, and second, the information automatically generated, three is a natural information, diagnosis and treatment of four was recorded. We index information to all their different form of electronic records, primary index number in the hospital under the form of virtual printing PDF files, to achieve the purpose of complete medical records.

2. Timely accuracy

On vital signs, electrophysiology, pathology, PACS, LIS, endoscope and other records of the formation of different interfaces and methods are required by different software in a timely manner the formation of electronic records; on the objective examination of test results and disease evolution, at a specified time node recorded, either automatically generated or the medical staff's treatment of written records, require timely and accurate, can withstand the patient, hospital quality control and inspection laws.

3. Non-repudiation

Handwritten signature database technology and step by step level can not be changed after submission, and process real-time disclosure, medical records, has made paperless electronic medical records storage will no longer be a problem. To display the watermark on the illegal printing techniques, so that the illegal termination and non-privileged users can not access to clean print of medical instruments, but also "special seal affixed medical instruments as a legal basis can be" prompted to resolve disputes only One version.

YouTube expected profit model


Sept. 8 news YouTube, despite the establishment of only 19 months, but has become the darling of the Internet video site. The video has reached 100 million, YouTube's success attracted other new startups and giant jealous, Microsoft entered the video sharing market, launched its own service; this summer, SKYPE and KAZAA also introduced a Venice project to become a YouTube killer.

In this hectic situation, people seem to forget that so far the video sharing is still a high investment, low profit, non-profit business. YouTube plans to launch a new business model, each user can put their own video content. It should create their own advertising, and plans to spread through the Googel and Yahoo.

YouTube monthly inputs from 900,000 to 1,500,000 U.S. dollars, most of the inputs to the server provider and broadband provider in the hands. As the YouTube video piracy issues are being addressed, if faced with legal proceedings, the cost will be higher.

More importantly, it faces a difficult problem, how to achieve profitability? YouTube can make money from this growth, while maintaining the user can expand. If the introduction of advertising, the user can be alienating. Given this risk, YouTube founders Chad Hurley and Steve Chen of the advertising business is not eager to implement. In a two or three minutes of video in the tentative 30-second commercials running. YouTube in the development of a new model that allows advertisers to establish a video channel, or to place the home page of YouTube video content.

To open up new channels for advertising, logically possible, but in this competitive environment, how to seek avenues of cooperation? YouTube, Warner Brothers introduced the first branded channels, and promotion of new Paris Hilton CD. But for those who are not content businesses, another method is to build a theme-based management of channels. Or YouTube through technical means and in accordance with the user's browsing interest ads.

Another problem is that, YouTube does not help advertisers achieve the best video content. Gartner analyst Allen Weiner said institutions, YouTube could create separate channels to provide more professional video content.

So far, YouTube executives have been no positive stand on the advertising business. Company wants users to pirated content on the automatic filtering, for advertisers to establish an innovative approach to community faces enormous challenges, such as organized or sponsored the film festival video competitions.

YouTube, a good beginning, but a new generation of mainstream sites and new start-ups than before, its impossible to have too much time to get into video services, real money.
