tethered shooting

On the eleventh day of Christmas…

Eleven Pipers Piping… so today it’s all about getting your pictures from your camera to you computer screen when you shoot tethered.

High-speed tethered shooting

Tethered shooting is a topic that is really popular amongst this site’s visitors and today I have a top tip about tethered shooting with the EOS Utility software to speed up the previews on your computer. EOS Utility is available to all EOS DSLR customers with their cameras.

RAW files are too big

If like me, you almost always shoot RAW, then you know that RAW images from an 18-22MP camera are around 25MB in size. To send this big file over a USB connection takes a little time. If you are photographing people then you will often shoot several pictures one after another in search of the right expression. The lag in seeing the pictures on the computer screen is significant as all that data backs up.

My suggestion is to shoot RAW + JPEG on the camera; even if that sounds counterintuitive.

I also ensure I have a big fast memory card in the camera since your camera will now have to hold all the RAW images plus the smaller JPEG images too.

EOS Utility can be configured to transfer just one of the images when shooting RAW + JPEG on the camera. So you can take a full resolution RAW image and have the camera also prepare a smaller sized JPEG with a smaller file size. This smaller file will transfer quickly over USB or WiFi (EOS 6D and EOS 70D folks).

Now your JPEG might only be 5MP, but how many megapixels is your computer display? My 1920 x 1200 pixel screen is just under 2.4MP.

About the twelve days of Christmas

The Twelve Days of Christmas start with Christmas Day and ends with the eve of Epiphany on January 5 th. The Twelve Days of Christmas dates back to English origins in the sixteenth century although the music is reputed to be French. The first publication date for The Twelve Days of Christmas (The 12 Days of Christmas) was 1780.
