Fellow UHH'ers.;
Started a new informal learning class on photography. I need to submit photos related to the class to be used in training presentation.
Using Nikon's Vnx2 software and just learning Photoshop CC (long ways to go). Problem: I need to reduce the MB size of the photos from the 3MB recorded on SD card and downloaded to processing software to 1 MB in order to send as an attachment to an e-mail to the class. UHH'ers have been great with info, so, hoping to get some good information on how to do this.
Thanks.

Photo Shop has a save for email feature that works very well.

You should ask the teacher what the dimensions, in pixels wide by pixels tall they require. Some clubs require 2048 pixels on the longest side, and a maximum file size of 500kb or 1 mb. This would result in an image that will fill a screen with a nice, high resolution image. More than likely you will make it under their max file size, if not, you can adjust the quality of the jpeg to make it come under the limit.

You can do this easily in Photoshop by displaying the image, and selecting the File>Image>Image Size menu option - You can select the new width size to be 2048, and if the width and height are linked (small "clip" icon to the left of width and height), you will end up with the correct height. The next step happens when you save the file. Do File>Save As, and select a variation on the file name - I usually add descriptive words like downsized to 1mb or 500kb. You will next see a dialogue box that offers some jpeg options. Your concern is the quality setting. There is a slider or you can input an exact number. Moving the slider to the left decreases the quality and lowers the file size. There is a checkbox for Preview - it should be checked so that you can see the file size as you adjust the quality in integer numbers. In Photoshop, this image would be just slightly over 1 mb with a setting of 8 and 480kb with a setting of 3.

I used Lightroom to generate these images, but the drill is basically the same, and you can be a little more specific about file size rather than have to pick from integer-based options.

As you can see, in this image there is little difference between the different quality levels of the downsized image. But the first, full-size image has the full resolution of the orignal capture, and when you click on download and then the + sign, you can see exactly how much detail was recorded.

There is no "Save for Email" option in Photoshop. But you can use File>Export>Save for Web which essentially combines the two steps in my process to a single dialog screen. You can adjust the image dimensions, quality and see the file size results in the bottom left corner of the image.

I use this in windows XP and 7 (Not sure if it works in 10 though):

It becomes part of the right click menu in Windows Explorer and simple to use.

Fantastic info. Thanks for the quick and thorough responses. First thing in the morning I am going to check all these out.
Thanks.

Buy Lightroom. You can export batches of photos to any pixel size you want with a click of a mouse. If you are working with the web, use 1050 pixels for the longest edge and your images will be 1 MB or less for the web. I process 300 images per day to post to Dropbox for real estate clients. Photoshop has no method for handling volumes of images. If you are downsizing a few, use 1050 pixels for the horizontal edge.

Click on >Save for web<, in the up-coming dialog-box you can adjust quality and size!

ok; save to web. Then how to I get access to the photo to attach to an e-mail?

You just store it were you like, what ever you choose, then when sending an email, you get it from there and attach!
