3 Photoshop Tips for Preparing Images for PowerPoint
Here are a couple of quick Photoshop tips for preparing images for a PowerPoint Presentation:1. Setting Backgrounds to White
Do you ever import an image into PowerPoint only to find out that what you thought was a white background, is actually not? There is a easy Photoshop trick to change any almost-white background to white.
- Choose Image > Adjustments > Levels
- Click on the Set White Point Eyedropper
- Click on the area of the image that needs to be changed to white, and voila!
2. Scale Images Appropriately
This is a strangely little known fact, but the size of a default PowerPoint slide is 10" x 7.5" at 100dpi. To avoid resizing images in PowerPoint, it's best to adjust images to an appropriate size in Photoshop before exporting. To resize an image use Image > Image Size.
3. Lower the Quality Setting on jpgs to Reduce File Size
Images add a lot of file size to a PowerPoint presentation. Using lower quality jpgs will help reduce the overall presentation file size. Lowering the jpgs file size and quality doesn't mean you have to make the image look bad. The best way to maintain control when reducing jpg quality is to monitor the image preview as you reduce the quality settings.
- Zoom the image to 100% (this is important to get an accurate preview)
- Choose File > Save As
- Select jpg as the file type from the Format drop down
- Type the name of the file in the Save As text box
- Click the Save button
- A dialog box with the jpg options will appear. Make sure that the Preview box is checked. Start adjusting the quality of the jpg down while watching the preview. Adjust the jpg quality to as low as possible without loosing a detectable level of quality on the image preview. Depending on the image, a quality setting of around 7 will drastically reduce the file size without changing the look of the image.
