How to resize your photos
for submission to our web site and slideshows
Digital photos comprise thousands of dots called pixels. The human eye 'reads' these pixels and translates them into an image. To achieve optimum optical quality it is important to have the correct pixel count depending on the application. Every size of photo print and every type/size of video display demands certain pixel specifications to reproduce high quality images. Here we present a simple approach to resizing your photos to the pixel count needed (or requested).
When you download your images from your camera they will be set to some predefined size and resolution. The camera manufacturers and the computer software accepting your images predefine many specifications including size and resolution. Simply stated, "one size fits all" is not applicable in the world of photography. In this brief guide we do not discuss the capabilities of different cameras and the complex world of sensors, processing, etc. Instead we look at how to adjust whatever appears on your computer screen so that the photo dimensions fit the application that you are going to use.
As an example, we have specified 1024 pixels (on the long side) for photos submitted to the club web site or for club assignments. Now, if you wanted to make high quality 11 X 14 prints from those same photos, the chart indicates that the image should be set to 3032 pixels (or larger) for excellent, photo quality results.
If you enter photo competitions or provide your photos for some other purpose, more often than not you will be presented with instructions relating to size/resolution.
We strongly recommend that you print out the resolution reference chart
and keep it handy.
Step 2. Resize your photos
Step 1. Select the resolution
Most photos are printed (prints, books, posters, etc.) or are used to display on a video screen (e.g. web sites, streamed to a TV screen, your laptop, etc.). Photo print sizes and video screen sizes each demand a certain number of pixels to reproduce a high quality digital image. The image 'Resolution Chart' provided here lists the pixel count for many applications:

For great prints it is essential that your video monitor is calibrated for color, brilliance, etc. The presentation provided by Jeff Fier at the December, 2015 club workshop meeting delved into this topic. His presentation slides are provided in the PDF file here:
On a recent club trip to shoot the night sky over Joshua Tree National Park we learnt a lot about night photography and different approaches to post-processing the photos. Our desert sky is magnificent (even more so up in Joshua Tree Park), give it a try sometime.
Here are some useful resources to help you gain the most from your night shots:
