Photoshop: Vanishing Point Tutorials

Leave a comment

Hello everyone,

Today I want to encourage you to deepen your knowledge of Photoshop.

Architects sometimes need to correct or amend visuals of their design. Visuals are in perspective (usually) and there is special tool called Vanishing Point which allows many kinds of modifications in perspective. You can easily put 2D images in perspective, copy and even clone in perspective and between different perspective grids!

First watch this video tutorial by Howard Pinsky (~8 min.)

and if you still need more information maybe try that one by tutvid (~18 min.)

The tool is present in Photoshop since version SC2.

Photoshop: Turning off the Pixel Grid

Leave a comment

I have stick in the office, technical problems with Overground again, and that’s why I can post another small tip. Something that annoyed me in PS – the Pixel Grid when you zoom in over 600%. It is turned on by default probably since CS5.

How to turn it off:

1. Permanently: select View > Show > Pixel Grid. To turn it off make sure Pixel Grid is unchecked. Photoshop will remember that setting.

2.Temporarily: select View >Extras  or press Ctrl+h (Command + h on Mac)

This will also turn off Grids, Guides, Layer Edges… everything under the Show menu. Next time when you open PS they will be turned on.

ctrl-H

If you don’t see the pixel grid menu option, then you most likely haven’t got OpenGL enabled in your Photoshop preferences. To fix this, select the Edit > Preferences > Performance… menu option. Make sure that Enable OpenGL Drawing is checked.

Photoshop Tip1 – Blend with Altphotoshop tip 1

Recently in my work for a different graphic designer I needed to remove from my B&W render with lights only (Vray Raw Lightning channel) all black color leaving only white light with a transparent background. I couldn’t render it but after some search I have found a way how to do it in Photoshop. This is how to:

1.Copy your image to a new layer. Optionally, place empty layer below.

2.Double-click the new layer thumbnail to open the Blending Options dialog.

3.In the “Blend If” section, drag the “This Layer” black slider to the right to remove the completely black background, then hold down Alt (Option on Mac) and drag the right half of that slider further to the right until you see the effect you’re looking for. (See the attached image)

4.Select All (Ctl/Cmd-A) and Copy Merged (Ctl/Cmd-Shift-C) then paste wherever you need the new layer with transparent background. (NOTE: If you have other layers below this layer, turn them off before copying so that all you retain the is transparency.) Optionally, Merge Down with empty layer.

5. At the end with Levels (Ctr-L) shift all grays to white.

I did it for shadows also (Vray Raw Shadows channel) I hope my readers will find application for this trick.
