Resize your digital camera images and preserve the
megapixel
It's important to maintain the high quality of your images (resolution) when you modify them.
Resolution is described by the quantity of megapixel, and more is better.
Megapixel, resolution, is the reason you bought your digital camera. Once you take pictures with
your camera you need to download them to your computer (or external hard drive). Once
downloaded, you should archive your images, rename them, and resize them for printing or for the
Web or to send to family and friends.
Change the image quality setting on your digital camera
Find the setting on your digital camera called ‘Image Quality’ and set it at the highest possible
setting.
My 10 megapixel digital SLR Rebel XSI camera’s function for image quality is called simply ‘Quality.’
I have 12m 4247x2848, the lowest option I have is 3.4m 2256x 1504. I always set my camera on the
highest setting 12m 4247x2848.
Fewer higher quality images is better than a bunch of lower quality images
The highest image quality setting means fewer pictures on your memory card. A lower quality
setting means a lot more pictures. Buy another memory card if you want to take more pictures or
buy several. They can be inexpensive.
Other digital camera options that will impact the number of photographs you can take on your
digital camera is the type of digital image output. Most of you will take pictures using the JPEG
option. You may also have TIFF and RAW options. JPEG is the smallest file size but the image
degrades every time you use it, move it, download it, or save it. The other images are larger file
sizes so this is the tradeoff.
Refer to your digital camera user manual if you can’t find this option on your camera. If that doesn’t
work take it to a local camera store and see if they can assist you.
Use good photo editing software and keep image quality integrity
All photo editing software is not created equal. The software that came bundled with your camera
may not give you the options you need. The ability to change resolution manually is the reason I
believe Adobe Photoshop Elements (or CS3 or other PhotoShop editing programs) is a cut above
the rest. Most Adobe PhotoShop programs allow you to manually resize images, these functions
may be in a different locations, however.
Adobe Photoshop Elements has a low price is geared toward photographers.
Resolution recommendations
Resolutions is expressed in dpi (dots per inch) and as a quantity of megapixel.
For printing = 300 dpi or higher
For the Web or to send to family and friends through e-mail = 72 dpi
Remember, what you see on the screen in Adobe Photoshop is not the actual size of the picture.
You have to manually resize the image.
Example: resizing your images and keeping your megapixel
1. Open Adobe Photoshop Elements
Before you try any of these resizing techniques make a copy of your image. Goto 'File' pulldown
menu and select 'Save as'
2. Goto ‘Image’ pulldown menu, select ‘Resize’ then ‘Image Size’
3. Uncheckmark 'Resample Image'
Deselecting ‘Resample Image’ allows you to proportionately resize
width and height and resolution as all three are connected
In this example, only width and height are connected
This second image is correct. You want width, height, and resolution connected
4. Change your width height and resolution!!!!
Try changing your resolution to 300 dpi. Notice the width and height get smaller. 300 dpi is the
lowest recommended resolution for printing. I would not print with a lower resolution. Do your
pictures print well? What is their width and height at 300 dpi?
Most digital cameras allow you to size your images down to a perfect 6x4 or 4x6. Let's try that:
