How View > Print Size works; or the mythical “72 ppi”

Greetings!

There is a common misconception that the correct “resolution” for images viewed on a monitor or the web is 72 ppi. One of the undesirable side-effects of believing this misconception is that it can lead you to get the wrong display of images with the View > Print Size command in your image editing application.

The problem is that View > Print Size depends on your application knowing the correct screen resolution and your screen resolution is probably not 72 ppi.

For example, the screen resolution of my laptop monitor is 147 ppi (1920 pixels over 13 inches). Let’s say I have an image that will print 6” x 4”. By default, View > Print Size displays this on my laptop at 2.94 x 1.96. Why? Because Photoshop thinks my screen resolution is 72 ppi (the mythical default number). So, by default, View > Print Size displays images at 72/147 = 49% of real size.

In Photoshop, you can set the screen resolution in Edit > Preferences > Units & Rulers > Screen Resolution. Setting mine to 147 results in View > Print Size correctly displaying the image at 6” x 4” on  the screen.

To determine your monitor’s screen resolution, just measure the width of the displayed area in inches and divide that number into the pixel width of your display settings. For example, suppose your display settings are 1600 x 1200 pixels and you measure the width of the displayed area as 13.9 inches. Then your screen resolution is 1600 / 13.9 = 115 ppi. Using that setting in Photoshop will produce the correct image size with the View > Print Size command.

It’s a good idea to verify that you have the right setting by placing a 6″ x 4″ photo up to the screen and comparing. If the image on the screen is smaller, then increase the screen resolution setting. If it is larger, then decrease the screen resolution setting.

NOTE: If you’re using a CRT monitor, be aware that the vertical screen resolution can be different than the horizontal screen resolution. Before you measure your screen resolution, you need to use the monitor’s hardware controls to ensure the display is ”square”.

How to make MagicJack work on a server

We use a MagicJack USB dongle for long-distance telephone calls over our Internet connection. The price is hard to beat and the unit works amazingly well most of the time. We have a cordless telephone base unit connected to the USB dongle and the handsets can be used throughout the house and deck. Provided of course that the MagicJack software is running.

MagicJack does not operate as a Windows service. It needs its application to be running under a logged-in Windows user. Initially, I had the USB dongle plugged into my desktop workstation. But since I often reboot or run heavy CPU applications, my workstation was not the best place for running the MagicJack.

Recently, I set up another computer on our network as a file server and I also wanted it to host the MagicJack instead of my workstation. This server would run Windows 7 and it would be headless (i.e. not have a monitor, keyboard or mouse of its own). To manage the server, I would log into it using Windows Remote Desktop Connection . The question was: could I get MagicJack to operate in this evironment?

In my initial attempts, the MagicJack software kept crapping out, but…

Arts on the Avenue a Great Success!

Thanks to everyone who came out for “Arts on the Avenue” in Ladysmith on Sunday. The weather was awesome and we think more people came through than ever before. For our part, we sold some stuff and we met a lot of very nice people, many of whom signed up for pottery classes and took printing brochures and business cards. What more could one ask?

Thanks again!

We look forward to seeing everyone again next year!

Cheers!

Ladysmith Camera Club - August Theme Shoot “Conflict”

I’m still catching up but not nearly as late this time! The theme for August 2009 was “Conflict”. I don’t know if it was a case of too many folks in a happy mood or the exceptionally wonderful weather we’ve been having on Vancouver Island last month, but our members had some trouble producing “Conflict” images. Even so, we did get some good ones. Click here to see the top 3 results.
