Processing Images in iPhoto

Photo’s taken with a digital camera need to be reduced to kb size to use in your word docs. Changing image size and/or cropping your image can accomplish this. The minimal steps included in this document should produce a good quality image but for more extensive help please refer to the Wellesley College Computing website. Here you will find directions for downloading software, such as Photoshop, as well as directions for using it to edit your digital photos. The link for PCs (search under P for Photoshop after getting to the page) is http://www.wellesley.edu/Computing/pc.html and for Mac OS operating systems it's http://www.wellesley.edu/Computing/macintosh.html.

If working in iPhoto:

Open the image in iPhoto by double clicking on it.

Go to Photos: photo info and note the current size of your picture. You need to reduce the image to kb size to avoid filling mailboxes with their quota when you try to email your photos or your documents.

Below the image is the edit icon:

Click on edit: Notice your picture will reframe with new icons

Click on Crop and cut out the section of the picture you want.

Check Photos: photo info – if you are now in kb (not Mb) you can use this photo

Click on effects or any of the other options to try to improve the clarity of your image.

If you are satisfied with the photo: export it to the desktop and use this version.

If the image is still too large, use the icons on the lower right

Clicking email will open this window

Use the drop down menu and select small

Select small and save the picture.

Photoshop provides more options for improving your photo and it is on the lab computers. After downloading to iPhoto on the macs in the lab, select the images you wish to modify and drag them to a desktop or to a folder with your initials. Be sure to trash your photos after you select and email the final version to the conference.

Open Photoshop and within Photoshop use File: Open. Browse for your image.

Go to Image: Image size: and notice the size and resolution of the image.

This picture is still too large. Notice it is 1.69M.

You can change the size of your picture in several ways but crop it first.

Be sure the rectangle tool is highlighted

Outline the area you wish to keep and click Image: Crop

Once you have the area you wish to keep, click on Image: Adjustments: Auto color to see if the computer can enhance the image for you. You can also adjust color on your own Image: Adjustment: levels. Once you are happy with the area and color save the image

Recheck the image size, most likely it will still be too large.

To reduce the size, start by changing the image width and height, this will provide you with a way to keep images similar in size. The shape of each cropped image is important; similarly sized images will make a more attractive figure.

If your image is still too large, you can change the resolution. Usually a resolution of about 100 will bring a cropped image to a reasonable size (kb).
