Q: I manage a small wechat group. I would like to add one more person as group admin. However, I don’t see the option under Manage Group. Why?

A: The group small than 40 people doesn’t have this option.

Q: Is it possible to save Photoshop history so that I can show them to someone?

A: It may have many options.

1. Snapshot: snapshots can be useful when making large changes. To create a snapshot, in History panel right click on the history you want to snapshot, and then New snapshot. However, Snapshots are duplicates of your image at a particular point in time, similar to saving a document with an alternate name to create a copy of that document and available only during your current work session. In other words, it doesn’t give you step by step history, and if you save and then re-open it, you loss it.
2. Create an action: you can create an action by click New Action in Action panel, and record anything you do. Photoshop actions enable you to record a repetitive process and save that information as an action which you can then use for other tasks down the road.
3. Layer Comps: to create multiple compositions of a design layout to show your clients, you can create comps out of your image’s layers by using the Layer Comps panel. Here is how: 1) Open a file with multiple layers in Photoshop. 2)Choose Window > Layer Comps to display the Layer Comps panel. 3) Click the Create New Layer Comp button at the bottom of the Layer Comps panel. This creates a new comp that shows layers as they currently appear. 4) .Type a name for the comp and add descriptive comments. 5) Select Visibility, Position, and Appearance (Layer Style). Selecting all three options ensures that the layer comp will appear exactly as you want it to appear. 6) Click OK. The current state of the layers has been saved as a layer comp. This means that the image’s current appearance has been saved as a layer comp. 7) Using the Layers panel, make changes to the image: hide some layers, show others, or add more images. Your goal is to make the image appear significantly different than it appears now so you can save a different layer comp. 8) Repeat steps 3–6 to save your changes as another layer comp. 9) In the Layer Comps panel, click the left column next to the layer comp you first created.
4. Save with history: You can store a text record of the edits that were made to a file in the metadata with the History Log. To save with history, go to Edit>Preferences > General). It is not the true history; you cannot revert the changes, for instance. This is just a text log of the changes you made.

Situation: the client has been using Voyager 5200 UC Wireless Headset for years. After she upgrade her computer, the Voyager 5200 UC Wireless Headset can receive a call and make a call, but doesn’t work with the PC. She can’t listen or record on PC.

Troubleshooting: Installing and upgrading Plantronics Hub Installer software should fix the problem.

There are 3 focus modes to choose from in Sony A7R: autofocus, manual focus, and Direct Manual Focus (DMF). Autofocus focuses the lens for you, and manual focus puts you in full control. Direct Manual Focus is a hybrid of both: When you’re in this setting, press the shutter button halfway to engage the autofocus; once the camera grabs focus, you can then rotate the focusing ring on the lens to ensure accuracy.

If you are using autofocus, you can press AF/MF to switch from AF to MF.
