Project 1: Composite Movie Ad 976. Choose Image>Image Size.You created this file at 300 pixels per inch, which is appropriate for commercial print requirements. For web distribution, however, 300 ppi is far more than you need. To further reduce the file weight and resulting download time, you should downsample the file to 72%u00a0ppi %u2014 an appropriate resolution for most web display requirements.7. With the Resample option checked in the Image Size dialog box, change the Resolution field to 72.When the Resample option is checked, changing the resolution does not affect the file%u2019s physical size; rather, the actual number of pixels is reduced. In this case, at 72 ppi, only 630%u00a0%u00d7%u00a0810 pixels are required for a file that is 8.75%u02dd %u00d7 11.25%u02dd.8. Click OK to finalize the change.9. Choose File>Save As. Click the Save on Your Computer button if necessary.10. In the resulting dialog box, choose JPEG in the Format/Save as Type menu, then click Save.You are using the Save As process so that you can review the compression settings that will be applied in the resulting JPEG file.11. In the resulting warning message, click Replace/Yes.Because you did not change the file name, you are asked to confirm whether you want to overwrite the existing JPEG file.12. In the JPEG Options dialog box, make sure High is selected in the Quality menu, and then click OK.When you first saved the file at the beginning of this exercise, the resulting JPEG file was over 1 megabyte. By%u00a0reducing the resolution, the file is now approximately 200%u00a0kilobytes.13. Close the active file.
