Example text

Let’s say that you have scanned and edited a hundred images and are ready to archive them to CD. You want to convert them to 300dpi JPEG files in a new directory. To do this, simply start the actions recorder and perform all the required actions for one file. Stop recording the action, then apply the new action to the entire directory of images. The program then loads each file, changes it to 300dpi, and saves it to a new directory as a JPEG file. Best of all, this all happens unattended, so you can be in the next room watching Sea Hunt reruns.

If you do decide to go with bulk scanning, we highly recommend that you try to group your images according to exposure and subject matter. Put your macro images together and organize your wide-angle images so that you can scan them faster. Select one image from each group and make a test scan. Make any necessary adjustments and then scan the whole group. You will find that most of Most of the scanned the scanned images will closely resemble your first images will closely scan, so very little adjustment will be necessary in resemble your first Photoshop.

Draft resolution. DIGITAL RESOLUTION 45 5 PHOTO SOFTWARE BASICS B efore you can start editing your underwater photos with accuracy and efficiency, you need to learn the basic software editing tools and understand how they work. These tools are not really difficult to learn to use, it just takes time and practice. The key is to push all the buttons, read the manual, practice using test images, and take advantage of the help function. Before long, you will be amazed how this knowledge will enable you to quickly improve your underwater images.
