Let's say you are working on a file that has so many details which need a constant zooming and scrolling. You can use the zoom tool to get a closer detail and
zoom out to check how it looks from far. Another way is to use the Navigation panel to control the zoom and scroll.
Did you know Photoshop has this wonder option called Multiple windows of the same document?
01. I am using this 'Humongous World Map' for this tutorial.
For more information about the map >> Humongous World Map (Highly detailed map with 8000x7000 resolution made with shape layers inside Photoshop. 7 Continents, 267 Countries and 129 Oceans, Seas, Gulf and Bay.
Completely editable with organized layers)
02. To open a second window of the same document, go to the Windows / Arrange / New window for <document name>
If you have two or three different documents opened, active window will be shown here.
03. This is not a duplicate window, it is the same document in different window, you can think of it like 'Mirroring'.
Making changes to one document will reflect on the other window.
04. You can also create more than 2 windows of the same document. Any document you work will be
the original. You can Show ruler, Guide, Rotate, zoom in and out for one window without affecting the other. This is a huge time saver if you have dual monitor.
Notice the image below. For the first window (left) the Ruler is visible. Second window has nothing and the third window has Guide. Also note the zoom size at the
bottom of each window.
05. With all these multiple windows, the layers panel is only one.
06. After you made changed, you can save your document from any window.
Here i have included 'United Kingdom' to the map, without saving i'll close the window directly.
On the second image i have closed the third window (the one with the grid). On the third image i have closed the second window. Till now the document is not saved
and there is no save dialog box.
Only when i close the last window the save dialog popups.
Snapping is one of the easy option to find the center of the object/canvas quickly. The guide from the ruler will help you to snap automatically to the center and the corner of the object/canvas when
you drag and drop it.
Lets see how it works.
01. By default if you drag the guide from the ruler slowly to the middle of the canvas it automatically snaps to the center of the screen. This works in both directions.
Make sure the 'Snap' is checked from the View Menu (View > Snap)
02. If you create a simple selection in the canvas. Dragging the ruler will snap to the center of the selection and not the canvas.
03. Also this works on Lasso selection.
If you extend or Add more selection to the existing selection, dragging the ruler again will automatically snaps to a new center point of the overall selection.
04. The selection does not have to say inside the canvas always. If the selection goes outside the canvas, dragging the guide will find and snaps to the center of the selection.
05. Snapping works everywhere. Just like selection, it also works on any created pixels
06. If you have multiple pixels in a layer, you can turn on the 'Layer Edge' from the View menu to see it better.
View > Show > Layer Edges
07. To explain this better, i have used a green dots and a magnet. The green dot is a snapping location.
(fig 07 - 01 )
If you have grouped different layers and put them as one. Dragging the guide will sees all the individual layer + the canvas dimension.
(fig 07 - 02 )
If the layer is selected, the snapping works on the selected layer and also for the canvas.
(fig 07 - 03 )
If none of the group or layer is selected, the snapping works on the canvas. This is default.
08. Above all, if you make a selection, the snap works only on the current selection and it does not see anything. Notice i have selected the layer.
09. We saw earlier the snapping works on both direction, you can also drag the guide from one direction (horizontal or vertical) and hold the 'alt' to snap to the opposite
Snapping on Smart object consider as one object or canvas, and does not see any individual layers inside the smart object.
Snapping also works on Text layer, Shape layer or any opened documents.
