This post talks about some of the options for exporting images from Photoshop to the web especially using the Save for Web dialogue box.

The goal is to save the image for the web. Before doing so, the image must be scale down to an appropriate dimension.
By changing the quality of the image, and with changing the format into JPEG.

Working with document templates

Using Templates allows you to make new documents with any desired properties very quickly and easily.
And in this post, it introduces:

  • how to use the Templates dialogue to create a new custom image
  • hot to edit a new custom image template.
  • For create a custom template in the Templates dialogue, what needs to do is goes to Windows, Dockable Dialogues, Templates.
  • Then you can see a list of the available templates that can be used to create a new template.
  • All you have to do is choose the template you want and double click it.
  • There are also buttons to create a new template, to duplicate a template, to edit a template, and to delete one.
  • Once you want to edit the name of a template, you can just double click on the name and type down the new name.
  • And if you want to edit the icon for the template, also double click the icon here.
  • Or by clicking the template at once, then choose“ Edit Template”, and entering the number you would like to adjust. Finish this step with click “OK”.

Saving selections

By saving selections, you can avoid having to recreate a selection every time you need it.
This post tells us the two basic ways of saving selections:

  1. re-activating saved selections
  2. Saving selections as channels.

The first one is pretty simple, the only thing you need to do in order to do is to leave the selection active when saving and close the file.

The second is to save the selection as a channel.
To do that, just go to the select menu, and choose save to channel.

In the channels dialog, the saved selection will display as an extra channel.

In conclusion, this post introduces both Photoshop and Gimp’s function and some skills while utilizing them.
