PS 08 - How to Link/Unlink Slices

Optimizing multiple slices can be done with linking slices together. If you are going to have same optimization for all the slices, you can link them together instead of selecting each and every one separately. You can select one of the linked slice and assigning a format will share the same format for all the linked slices.

Linking is for image optimization only, it does not affect the slice behavior (layer based slice / user based slice). But, un-linking auto slice will promote to user based slice.

Linking slices together will display a link symbol next to the number sequence, by default all the auto slices are linked.

(fig 1.0)

To link the slices, go to ´Save for Web´ dialog box (File > Save for Web) and select the slices you want to link. (fig 1.1) i have selected slice 03, 13 and 07 (hold ´Shift´ when selecting multiple slices).

After selecting the slices, go to ´Optimize Menu´ and select ´Link Slices´(fig 1.1 - 2). This option (´Link Slices´) activates only if you select more than one slices.

(fig 1.1)

You can see the links in the selected slices, which also display color for easy viewing. Inside save for web dialog box you can see the linked slices with colors, but after you closed this window and go to working area (fig 1.2 - 2), you will only see the link and not the color.

(fig 1.2)

Once the slices are linked, select any one linked slice and change the format.

Here (fig 1.3) i have changed the format to WBMP, just so you can see it more clearly. Changing format for one slice will change all the other linked slices with the same format.

(WBMP is a standard optimizing image format for older mobile devices where it supports only 1bit, black and white)

(fig 1.3)

This will save a huge amount of time. Saving all the slices at once will save each and every linked slices in their own format.

(fig 1.4)

As you can see the (fig 1.5) the format change and the color are reflected only inside the save for web dialog box and not in the working area.

(fig 1.5)

By default auto slices are linked together, you can notice the link symbol next to the number sequence, you can also unlink any one of the auto slice from others or select multiple slices by holding the shift key and unlink them. Anytime you unlink any one of the auto slice will get promoted to User based slice.

(fig 2.0)

To unlink the auto slice, go to save for web dialog box and select the slice you want. I have selected the auto slices in-between the blue boxes (fig 2.1 - 1), and go to optimize menu and select ´Unlink Slices´ from the menu.

(fig 2.1)

Not only it unlinks all the selected auto slices, but it also promote to user based slice. Once promoted, these slices are no longer an auto-slice.

In the Essentials for Slice Select Tool III you can learn many ways to unlink auto slices.

(fig 2.2)

You can also remove the promoted auto slices, just select the slices and press delete. Deleting the promoted slice will bring back the auto slice. But you cannot delete any user based slice which created with slice tool and expecting it to promote to auto slice.

Try it out

- Select any auto slice
- Go to ´Optimize menu´ inside save for web dialog box and select ´Unlink Slices´ (this option is available even if you select one slice)
- Press ´Done´ to close save for web dialog box.
- Select the same slice in the working area, you will see the handles.
- Press 'Delete'

 (fig 2.3)

If you are interested you can buy this keyboard [here]

Deleting the promoted slice will bring back to auto-slice and also retains the same number sequence and links. Please note this works only on auto slices only.

(fig 2.4)

Lets see how to unlink all slices at once, we have couple of linked User based slice and Layer based slice along with auto-slices here.

(fig 3.0)

Even without selecting any slice, you can go to optimize menu and select 'Unlink All Slices'(fig 3.1 - 1). All the linked slices will be released (fig 3.1 - 2).

Note, this works only if you have any link on user based slice or layer based slice. This won't work on auto slice even if you select them. If you want to unlink auto slices, you have to use 'Unlink Slices' from the options.

(fig 3.1)

Linking slices is very useful when you want to share one image format for a set of graphics.

You can Link, Unlink Slices, or Unlink all Slices to any of the slices, but these options is available only inside 'Save for Web' dialog box. If you are saving your image through save for web dialog box, there are some limitations in the image format.

PS 07 - How to Turn Off the Transformation Values

Transformation values are the great new addition inside Photoshop CS6, its a powerful feature which display the values straight-a-way without opening the info panel.

Let me tell you why it is powerful, then you can decide whether you want to keep it or not.

Transformation values gives you the info for the object right away. And it only appears when you draw the shape on the screen, after you release the mouse button it goes away.

Sometimes you need to open the info panel to check the dimensions while drawing and it can take up your screen space, but with this transformation value you can get rid of the info panel and you can work freely even in full screen mode.

(fig 1.0)

It displays more than dimensions.

Dimensions:	When drawing any shape or even cropping
Dimensions + Coordinates:	Hold the 'Spacebar' to display the co-ordinates
Height:	Displays only the height value when you adjust the height position.
Width:	Displays only the Width value when you adjust the sides
Angle:	When you use perspective transform, you can see the angle right way
Rotation:	You can see the rotation values while rotating the object
Directions:	When moving the object to any side
Angle + length:	When drawing with line tool

(fig 2.0)

I agree, not everyone what these information to be displayed on the screen. And here's how you can turn them off.

Go to Edit > Preferences > Interface. You can use 'Ctrl + K' (Cmd + K in Mac) to open the general preferences and select Interface from the list.

(fig 3.0)

You will see the option called 'Show Transformation Values. Select 'Never' from the options. This will hide the values.

If you want to keep, you can also try other options in the list.

(fig 3.1)

Never:	When will never display the values (just like in the older version of photoshop)
Top Left:	When Display's top left
Top Right:	When Display's top right
Bottom Left:	When Display's bottom left
Bottom Right:	When Display's bottom right

(the display value box will change based on the direction you draw)

(fig 3.2)

You can turn it on at any time, but this option is available only as a interface option inside preferences panel.

Photoshop CS6 - Essentials - The Crop Tool

Cropping in Photoshop CS6 has improved drastically compared to CS5, at first its hard to control and might be little confusing, but once you get your hands on, its pretty easy and powerful.

Unlike the older version of photoshop, you don't need to draw a rectangle on the screen to display the cropping box. In CS6, when you select the cropping tool the cropping box appears immediately with cropping handles.

Crop Tool Options Bar

1. Tool Presets

Tool Presets helps you to save your presets which you can use it for later use or you can access even if other tools selected. You can also save your presets in a folder and you can load them in the older version of photoshop or even you can share it with your collaborators who are working on a same project.

 2. Aspect Ratio Options
Clicking the dropdown arrow will show you the presets and other options for the aspect ratio.

Unconstrained
This option will let you freely adjust any of the cropping handles without constraining to any aspect ratio.

Original Ratio
Will maintain the original aspect ratio of your image. Lets say you have a 16x9 aspect ratio of a frame and if you crop the image, the ratio is still maintains to 16x9. 

Presets
1x1 (square)
4x5 (8x10)
8.5x11
4x3
5x7
2x3 (4x6)
16x9 
are the presets which ships along with photoshop. You can use them if you want or you can create your own

Custom Presets
User presets are displayed below the photoshop presets.

Save Presets
You specify the width and height in the options bar and click the Save Preset from the drop down menu, which will bring a pop-up window. You can give any name you want, and click 'OK' will add that to the preset list.

 Delete Preset 
This will delete the preset on the list, selecting this option from the drop-down will bring the pop-up box ‘Delete Crop Preset’ where you can see the available presets, select the one you want and click delete will remove that preset from the list.

Crop Image Size & Resolution
You can use this option to save your presets with resolution. The width, height and resolution you add here will display on the current opened image. If you want this to be on your preset list, you can select 'Save as Crop Preset' at the bottom of this window and click 'OK' will display the 'New Crop Preset' box to confirm the name and it'll added on the list.

  
If you select the Source from the dropdown menu, you have an option to select Front Image, (current image aspect ratio and resolution) or Crop Box (crop region on the current image with resolution) and also you can select any opened documents, selecting any of these will automatically fill the width and height in the field box including the resolution.

You can see the image below, i have three documents opened 'Front Image (current document) and the others are at the end of the list.

Rotate Crop Box
This will rotate the crop box in the image, you can also press 'X' on the keyboard for shortcut.

3. Orientation

Which is the same as the 'Rotate Crop Box' under the aspect ratio options. Also the same shortcut key 'X' on the keyboard.

4. Straighten

This will straighten the image. This tool acts much faster than the 'Ruler Tool' under eyedropper. 

In Ruler Tool under eyedropper you have to draw a line on the image and click the 'Straighten Layer' button on the options menu to straighten the image. That leaves with empty pixels around the image and you have crop the image to remove those pixels.

But here in crop tool, you draw a line and you release the mouse, the image is cropped immediately. And you can still rotate or crop the image without committing. And if you want to cancel this operation just press the 'Esc' key. It is as simple as that. 

If you are in the crop tool, pressing the 'Ctrl' in the keyboard will toggle the tool to straighten. 

5. Overlays

Overlay are the grids that appear inside the cropping box. You can turn them off or turn them on, and you can also rotate them.

In the earlier version of Photoshop we have only two grid options, Rule of Thirds and Grid. But in CS6 we have six type of overlays to can choose from. Rule of Thirds, Grid, Diagonal, Triangle, Golden Ratio, and Golden Spiral.

Three options for displaying overlay on your image, Auto Show Overlay, Always Show Overlay, and Never Show Overlay.

Auto Show Overlay 

Will display only if you select the cropping box. You can see the image below, the first image has a bounding box but no overlay and the second one is the same, but with the mouse click you can see the overlay.

Always Show Overlay
This will display the overlay always inside the crop box.

Never Show Overlay
Will never show the overlay, even if you click and drag the crop box. If you do not like overlay all together, then you can select this option.

Cycle Overlay
This will cycle through all the six overlays, you can also use the keyboard shortcut 'O'.  

Cycle Overlay Orientation
You can change the orientation of the overlays. And the shortcut is 'Shift + O' which rotate the overlay, this is best for Triangle, Diagonal, and Golden Spiral. Other overlays like Grid and Rule of thirds are not clearly visible, since both has an even pattern.

6. Additional Options
Additional options will give you more control on the crop tool.

Use Classic Mode
One of feature in the additional crop tool options is to turn off the new cropping features. Photoshop let you turn them off so you can use the crop box just like in the older version.  

Use Classic Mode will disable the Auto Center Preview, Show Cropped Area and as well as Auto Adjust Opacity. You can also use the keyboard shortcut 'P' to toggle On or Off the use classic mode option.

Remember, when you select the crop tool, make sure you select the crop box (in the image) to activate the cropping handles (or grids) then select 'P' to Turn Off or On to use the 'Use Classic Mode'. If the cropping box is not selected, pressing 'P' will switch your tool from crop to pen tool, which shares the same keyboard shortcut 'P'.

Auto Center Preview ('Use Classic Mode' should be Turned Off)
ON: This feature let you keep your crop box in the center of the screen, so if you move the crop handle the image moves and not the crop box.
OFF: Just like in the older version, when you move the crop handle the crop box moves and the image stays in the center of the screen.

In the example below, i have made a grid to illustrate this feature more clearly. I have moved the crop handle from top left to the bottom right.

The first image shows the crop box is in the center of the grid and it always stays in the center, and only the image moves. The second option is where the crop box moves and the image stays in the center.

Show Cropped Area ('Use Classic Mode' should be Turned Off)
This feature let you hide the cropped area. It basically show the canvas color, if you are in the full screen mode with black as a canvas then this feature helps you to focus on the aspect ratio more clearly. The keyboard shortcut is 'H' on your keyboard.

Alternatively, you can also use the crop shield to set to 100% with the Match Canvas as a color, which gives the same result but you cannot turn off or on with keyboard shortcut.

Enable Crop Shield
Enabling crop shield will turn on the cropped area color. This will help you to see how much the cropping is made.

Color
Match Canvas: Will match the color with the canvas color
Custom: If you want a different shield color then you can use this option, which brings the color picker.

Opacity: Control the transparency for the shield color, it works both for match canvas and the custom color.

Auto Adjust Opacity
If you select, move or rotate the crop box, the opacity for the crop shield will dim down. This is helpful if you are on the full screen mode and you have the opacity between 90% to 100% . By clicking on the image will reveal other pixels more clearly.

This will affect only the shield opacity and not the image. You can see above, on the left i have set the shield opacity to 80% and on the right when i select the image to move, opacity dims down from 80%.

If you Turn Off the shield this feature is disabled and also if you Turn On the 'Use Classic Mode' (older crop box) this option is not available.

7. Delete Cropped Pixels
One of the great new feature in CS6 for the crop tool is 'Delete Cropped Pixels' option. After you made the cropping, you can decide whether you want to keep the remaining image (cropped area) to be there or you want to delete them completely.

You can see the first image has a 'Delete Cropped Pixels' selected, and i have made a smaller crop box and committed which deletes the cropped pixels completely and you can see the file size has been reduced to half. 
The second image with uncheck 'Delete Cropped Pixels', even-though it is committed to small size the file size remains the same. 

Doc: 24.8M/51.3M 
(24.8M - is the size of the cropped image  and  51.3M - is the size of the original image)  
 
The advantage of keeping the remaining pixels is, you can come back anytime and and get your full image back, all the pixels are preserved, even if you saved and closed the document. 

8. Reset, Cancel, and Commit
These tools are available when you activate the crop box.

Reset will reset the commands. In the older version of photoshop it was called 'Clear'.
Cancel will cancel any operations on the screen and also deselects the cropping box selection (but the default cropping box display will be there) and Commit will accept any changed on the screen you made.

All three tools are activated only if the cropping box is selected in the image. If you select one of the preset from the 'Tool Preset' (not the aspect ratio preset) only the Reset Button is visible.

Reset: 
When you make custom aspect ratio in the width and height box, you can reset to clear the box. If you have made any cropping in the image or if you have rotated the image, you can press reset to go back to where you have started. Reset will still keep the selection on the cropping box and you can still see the grid. it just resets your action back to 0.

But remember reset is not like a revert command under File menu, which takes you back to the start of the image. 
Lets say you have an image with 500x500 px and you cropped to 250x250px and you have accepted the changes and committed, pressing reset after commited will not take you back to 500x500px. If you haven't committed but made some adjustments to the crop box, then using reset will clear the adjustments.

Reset tool will work only on these selected options and including the crop box adjustment on the image.

Cancel
Cancel will cancel the operation and deselects the crop box. You can also use the 'Esc' key on the keyboard to cancel the operation.

Commit 
Accepting changes. You can also use the 'Enter' key on the keyboard to accept the changes.

Right Click on the image
Almost all the presets and custom aspect ratio and other options you can access without selecting the crop box (first image). If you select the crop box you get extra two options, 'crop' and 'cancel' which is at the end of the pop-up menu.

PS 04 - How to Color your Menus

Coloring your menus in photoshop is one of the effective way for the beginner to fasten their workflow. It also help you to focus on the menu quickly without searching for it.

Coloring option is available for all the menus in the menu bar.

For this tutorial, we'll see how we can color our file menus with blue, which indicates all the open commands. I've made red for close and green for save, just so you know you can assign different colors.

The coloring option is available in the Edit menu. Edit > Menu.. and the keyboard shortcut is 'Ctrl+Alt+Shift+M'

If you are interested you can buy this keyboard set here

This option opens the 'Keyboard shortcuts and Menus' window. Select the 'Application Menus' from the dropdown 'Menu for' option, if its not selected.

Expand the File tab.

Click the 'None' to open the color set and choose the color you want for the selected menu.

With the 'Keyboard Shortcuts and Menus' window open, you can still access the menu bar to see which color you need to assign for the menus.
Because the 'Keyboard Shortcuts and Menus' window will display all the menus and submenus as a list and sometimes its hard to scroll down and see.

Note, even though you can access the menus from the menu bar without closing the Keyboard and  Shortcuts and Menus window, you cannot see the assigned colors, after you accept the modifications and click 'OK' only the colors will show up.

Once the changes has been made, you can see the colors in the menu, this won't go away even if you close the photoshop and open later.

For some reason you don't want to see the colors, then..

Go to the Interface in the General pop-up window in the Preferences dialog box (Edit > Preferences > Interface). If you want to use the shortcut you can use 'Ctrl + K' to open the General tab.

If you are interested you can buy this keyboard set here

From the interface option, uncheck 'Show Menu Colors'. This will temporarily hide the colors in the menus.

If you have used the keyboard shortcut 'Ctrl+K' the General tab will open first, then click the 'Interface' (left side) right below the General.

Once you clicked OK from the Preferences you can see the menus without colors, but remember this doesn't remove the the colors, it just hide them temporarily. If you go to Menu option (Ctrl+Alt+Shift+M) you can still see the colors and you can change them.

If you need to see those colors again, Just go to the 'Interface' from the preferences menu and check the 'Show Menu Colors'.
