Photoshop Navigation Pallet

The Navigation Pallet consists by default of three pallets docked together. You can undock any of these pallets by clicking on the tabs and dragging them away. You can then re-dock them by dragging them back to where they were or add them to other pallets. If you wish to remove them from view drag the tab onto your work space and click on the close icon at the top right corner. To bring it back go to Window on the menu bar and click on the pallet you want back.

The three pallets in the Navigation group are Navigator, Info and Histogram.

Navigator

navigator palletThis pallet allows you to resize your view of the image you are working on either by using the slider underneath the thumbnail, by clicking on the big mountain or little mountain either side of the slider which will change the size in fixed steps, or by typing in a percentage value into the box to the left of the slider. If your image is larger than the window it is in you can use the red box on the thumbnail to move around your image. Just click and hold on the red box and drag it about.

With all these pallets you will see a little arrow icon just below the close icon at the top right. Clicking on this will bring up other options one of which will typically be an expanded view.

Info

info palletThis pallet give you colour, position and size information of a target area which will be defined by your cursor. By dragging your cursor over your image you can see the exact colour readings for the pixels there. It will also show you the location in terms of x and y axis and the dimensions of any selection you make with the marquee tool. It can be used to locate hot spots and the darkest points in image.

 

 

Histogram

histogramThis is the most important pallet in this group. It is extremely helpful to be familiar with reading this tool. Many digital cameras have histograms available which work just the same. It basically is a bar graph showing the amount of pixels in your image that have a particular brightness value. In an 8 bit image there are 256 brightness values with 0 being at the far left and representing black and 256, representing white, at the far right. In this histogram there are not black or white pixels only values in between. That means there are no blown out or underexposed areas. A high peak right at one end or the other would indicate blown out areas. I discuss the histogram and how to use it in more detail in the next section here.
