There are several reasons for holding on to each and every one of the images taken on your photoshoot, until you get back home and view them on your computer.
Travel photographer Lara Joy Brynildssen has put together a great article over at Digital Photography School. She explains why it’s so important not to delete any images while your at a photoshoot.
You may not only lose some real keepers because you can’t see them well enough on the LCD screen, but you could also damage the memory card you’re using.
Formatting is better for your memory card than deleting
Rather than deleting images, the gold standard is to download your entire card, reformat it, then start shooting again. Every photographer has varying opinions on this but this method seems to save wear and tear on your memory cards.
While they aren’t as expensive to replace as they used to be, they do last longer with more care. Reformatting rather than deleting also seems to prevent your card from corrupting, which saves you the time and expense – and panic – of dealing with that issue. It’s never pleasant to download a card and realize half your day’s shoot is corrupt and won’t load.
Usually, recovery software works and you can eventually retrieve those images. But if skipping in-camera deletion helps prevent corruption, then by all means, let’s all stop doing it.
Chimping and deleting takes you out of the moment
While you’re chimping and deleting images, you’re no longer in the moment. You take yourself out of the present and start reviewing images from the past. If you were on a roll or having a moment of magical oneness with your camera and your subject, you’ve just disrupted all that.
When you start pressing the delete button, you’re pressing the disconnect button too. You’ve stopped being an artist to chimp, delete, and save space on your memory card. Will you be able to immediately reconnect with your inner artist when you’re done chimping and deleting? Most of us can’t get back to that creative place quickly or easily so once we get there, it’s best to stay focused there.
You’ll miss some great shots while your head is down
What are you missing while your head is buried in your camera’s LCD? You’ve traveled all the way to [insert your favorite place here] to photograph [insert your favorite subject here] and instead of photographing it, you’ve let your OCD take over and you’re cleaning up your memory card. Is that a good return on your investment? Are you making the best use of the time and money you’ve expended?
When you bury your head into the technical parts of your camera, you miss so much. Yes, a quick glance at your histogram is fine. Yes, you can quickly double-check your focus to make sure you’ve nailed it, but then keep shooting before you lose your mojo.
