1. Smart object and Smart filters
In short, Smart Object and Smart Filter allow you to revert the actions made on images; let it be effects, filters, or different sizes. In another word, once you’ve converted them to Smart objects/filters, they are non-destructive, original state, and be easily recovered when wrong decisions are made.
An image, after converting to Smart Object allows you to resize to any dimension without losing the image quality. To convert an image to Smart Object, right-click on the image layer, select Convert to Smart Object.
An image, after converting to Smart Filter allows you to remove and re-apply filters without needing to bring back the original image and start all over again.
2. Absolute Positioning
Say you have a canvas size of 500×300 and you want to place the iMac icon right in the center/middle. By positioning the icon manually with a mouse, or perhaps with some Photoshop ruler guidance I argue it’ll be slightly inaccurate and it’s time-consuming.
Here’s a simpler way. Simply highlight the canvas size, make sure you are selecting the iMac layer, select the Move Tool V and click on these 2 buttons on the top.
Align vertical centers
Align horizontal centers
You can rest assured that your icon is now absolutely center/middle.
3. The Hand Tool
You’ve got a big size file but a rather small working canvas, if navigation from places to places within the canvas is troublesome, try the hand tool. Hold Space (your cursor will turn to a hand symbol) + left mouse click to move around your canvas. A pretty handy shortcut.
4. Layer Comps
Layer Comps is great in controlling the visibility of a combination of layers and folders. They are extremely useful when you need to communicate your design with your peers, superiors, or clients. It allows you to on/off any layers and folders at ease. All you need to do is define each visible screen to a layer comp.
Layer Comps can be found at Windows → Layer Comps.
5. 1 Click Zoom Reset
I think it’s a designer’s habit to zoom deep into a specific part, do some adjusting or tweaks and then move on to others. You can zoom in to an opened Photoshop document by using Alt + Control + +. To zoom really deep, just keep pressing the +.
No matter how many times you’ve zoomed in, you’ll just need one command to reset back to your original size. Here’s the keyboard shortcut you need, Alt + Control + 0 (Windows), Option + Command + 0 (Mac).
