Click OK and at this point it is a good idea to use the Unsharp Mask filter to sharpen the image. Note that at this new size, the image is only 1.9 Megabytes, a fifth of the original size. If Constrain Proportions is checked, the Height will automatically change proportionately. If the image is horizontal, change the Resolution to 100 ppi and the Width to 10". Lets go back to Photoshop and change the size of the image to more economically fit into PowerPoint. All those extra pixels are not necessary, as PowerPoint will not use them. Compare this to the initial pixel dimensions of the image to be inserted. PowerPoint defines the area of one slide (in On-screen Show setting of Page Setup) as if it were a piece of paper 7.5 " high and 10" wide at 100 ppi. Images do not need to be this big to appear well when projected so we want to reduce the pixel dimensions before inserting into PowerPoint.
This is a very large file and inserting only a few images of this size into your presentation will require alot of memory and likely slow down or even crash the computer. Note that this image requires 10.1 Megabytes of space (uncompressed) to save.
Make sure the Scale Styles, Constrain Proportions are checked and set Resample Image to Bicubic. Open the image you wish to insert into a PowerPoint presentation in Photoshop and open the Image Size Dialog Box. When you resize an image to place in a PowerPoint presentation, you will be changing the pixel dimensions as detailed in the folowing section. In this case by changing the Resolution to 300ppi, the Width and Height automatically changed to 7.68 and 5.12 respectively. Now when you change the values of either the Width, Height, or Resolution, the other values will automatically change while retaining the same Pixel Dimensions. We didn't add or subtract pixels, we just told the printer that we wanted a smaller, higher resolution print of the image.Īnother way to change the Document Size without changing the Pixel Dimensions is to uncheck the Resample Image box (red arrow) at the bottom of the Image Size Dialog Box. Also note that in this process the Pixel Dimensions stayed exactly the same. When you open the Image Size Dialog Box again, you see that the image will print at 7.6x5.1 inches at 300ppi. Be sure that you have the Constrain Proportions box at the bottom checked, this will make any changes proportional to both the height and width.

These are somewhat awkward dimensions, so I try to make the following changes as soon as I download an image: Change the resolution to 300 (this is a standard resolution for printing and publishing photographic images) and in the pulldown menus next to Width and Height choose percent. For some unknown reason, when you download an image from a digital camera it always sets the ppi to 72 at a large print size.
In this case, the print would be at 72 ppi (pixels per inch) at 32x21.3 inches. The lower box, Document Size, tells you what size the image would print if it were sent to a printer and what the resolution of that print would be. In this case, the image is 10.1 Megabytes (Mb) in size. The upper part of the box, Pixel Dimensions, tells you exactly how large the image is in pixels and how much space the image requires on the hard drive if it is uncompressed. Open an image in Photoshop and then open the Image Size Dialog Box under Image in the menu bar.

To optimize the file sizes of your images, it's important to understand how to use the Image Size function of Photoshop. Inserting digital images and movies into PowerPoint is easy, but care must be taken to optimize the file size of the images to keep the program from hanging up or crashing during the presentation. PowerPoint has become the most used slide show program fror teaching and training and most everyone in science will have to use it at some point. Sizing Digital Images For Powerpoint One of the most prevalent uses of digital imagery is in PowerPoint Presentations.
