Methods of creation of the image

• To cancel the last operation, use command Edit> Undo (Editing> to Cancel) or keyboard shortcut Ctrl+Z. Keep in mind that it is impossible to cancel some commands. To cancel some steps, click on prior event on palette History or by means of tool History Brush recover certain areas of the image.
  
• Periodically click by button Create new snapshot (to Create a new picture), allocated on palette History to save image versions. If you want to return to the appropriate version of the image, click on a picture miniature.
  
• Use an adjusting layer to experiment from times personal colors, and then unite adjusting layer with lower, thereby fixing the gained effect, or delete adjusting layer. By means of slider Opacity (Opacity) allocated on palette Layers, it is possible to weaken effect of application of an adjusting layer. To restrict action of an adjusting layer by what is allocated immediately under it, create cutting group (clipping group), including a layer allocated immediately under the adjusting.
  
• By means of command Edit> Fade (Editing> to Weaken) or keyboard shortcuts Ctrl+Shift+F it is possible to weaken effect from the last applied filter, a command of adjustment or the tool of editing without usage of a command of repeated action or a canceling; at performance of command Fade select the mode of mixing necessary to you and opacity level.
  
• To interrupt copying of the screen after command or filter application, select other tool or a command (if want to cancel a command while the performance indicator is displayed, simply push ESC key).
  
• Select the least possible resolution and image sizes taking into account requirements to printing quality. It is possible to create a sample of the image with smaller resolution, saving used commands in the form of action, and then to play back action for the same image with more high resolution. Remember that vectorial layers (layers of the edited text and figures) at the press have printing device resolution, instead of document resolution.
  
• Simultaneously display the image in two windows, big and small that it was not necessary to you permanently
  
• To change its scale.
  
• Save the difficult selected areas in the special half-tone channels named alpha channels (alpha channel) which can be loaded and used at any moment in any image. Or create a circuit or cutting circuit - they occupy much less disk space, than alpha channel. Afterwards they can be transformed to boundaries of the selected area.
  
• Use mode Quick Mask (the Fast mask) to transform the selected area to a mask which leaves the protected areas of the image visible, and the unguarded areas closes, then by means of the paint tool it will be possible to change the mask form. Ungear mode Quick Mask if want to transform the closed area reversely to the selected.

• As CMYK-files are processed more slowly, than RGB-files, use command Proof Setup> Working CMYK (Setting of a trial print> Worker CMYK), to have possibility beforehand to view the image in mode CMYK, and at the termination of operation with the image transform it to high-grade representation of type CMYK.
  
• Remember as much as possible "hot" keys. Begin learning with "hot" keys for a choice of tools (the section "Toolbar" above in this chapter see). For help use tooltip balloons or address to the list of "hot" keys allocated in the end to the book. "Hot" keys are specified and in the majority of the instructions resulted in the book.
  
• Try to select not less than 60 MB of a random access memory for program Photoshop or in 4 times more than the size of the document.
  
• Periodically use commands of submenu Edit> Purge (Editing> to Clear) to release a random access memory occupied for operation with Clipboard (Clipboard), commands Undo (Cancelling), palettes History (History) or for all aforesaid All All) - fig. 1.68. It is impossible to cancel commands of submenu Purge.
