How to avoid digital disaster

1 Comment

Currently in the news, here in Toronto, is the story of a hospital patient who had a family laptop stolen from his room. The laptop contained three years worth of irreplaceable photos of the patient’s granddaughter who recently died. The family is pleading for the return of the digital pictures.

(Added May 13: updated story here: laptop recovered but hard drive erased.)

In the days of film, people had no choice but to get prints made from their negatives. But in today’s digital world, many people keep their pictures only on the memory card in their camera or cell phone. This is always a huge mistake. Prints are not often made these days, as photos are usually viewed only on a device’s LCD screen, which saves the small cost of prints. This, too, is always a mistake.

Zooming big

No Comments

From time to time, some photographer friends and some “normal” friends (i.e. non-photographers) will send me pictures and ask that I make them bigger. Apparently, I do a good job. Well here’s my secret:

I’ve been using PhotoZoom Pro since version 1.0, back when it had the catchy name of “S-Spline Pro”. The software works as advertised. Unfortunately, I don’t get paid to say that, I’m just a happy user.

PhotoZoom Pro 3 [as of 12/2012, it’s up to PhotoZoom Pro 5] isn’t particularly cheap but BenVista just released a new “lighter” version called PhotoZoom Classic 3. This uses the same technology as the Pro version but it has slightly fewer features and costs less than half the price.

But I have a zillion-megapixel camera. Why do I need to up-sample?

If you can fill the frame with your subject all the time then you may not need this software. But if you need to resample after a huge crop, this software can do the job. If you need to up-size low-resolution pictures sent in from your readers or customers, then this software will be useful.

I’ve cropped images from 36 MB (12-megapixel Nikon D2X) down to less than 1/6 of the frame and then resized them back up to 36 MB with PhotoZoom Pro. Editors were none-the-wiser!

Certainly, after any large up-sampling, the final image is never as perfect as the original. But it’s garbage in, garbage out. If you start with a small, poorly-exposed, out-of-focus image, then you’ll end up with a big, poorly-exposed, out-of-focus image. This software, like all other interpolation applications, makes the photograph bigger not better. Although, sometimes bigger is better.

 

Being Different

“Performance artist” may be the best description for Chinese artist Li Wei. Although “crazy” could also be used.

Take a look at the mind-boggling photographs on his web site. (The site doesn’t seem to mention the name of the photographer(s).)

Aha! They’re all fake! Photoshopped pictures!

Actually, you might be surprised.

While several of the images were edited to erase the steel cables or ropes that supported the flying people, not all pictures were altered. Apparently, for a few high-air pictures, Wei just climbed up and did his stuff.

Many of his floating head pictures have no digital magic whatsoever but they do use old centuries-old trickery. Some of the floating heads in the “Dream-Like Love” series must have been Photoshopped because there seems to be no other explanation.

The web site also has small videos which show some behind-the-scenes activity. In one video, while dangling from a 25th-floor ledge, Wei is suspended only by a rope handheld by two other guys.

While this work was done purely for the art, apparently Wei’s plan is to move into advertising. Do you think wildly different pictures like this might help get a business noticed?

Does corporate photography always have to be safe (and boring)? When should a business take a risk with its marketing photography?

 

Reputation Protection

Earlier today, I received a panicked phone call from a photographer here in Toronto. He had lost some pictures on a memory card and had no idea what to do. His corporate client needed same-day delivery which he had promised.

This was the seventh time this year that a photographer has phoned or e-mailed asking for help to recover lost images.

Photographers, here’s the deal:

If you want to be a professional photographer, you MUST have recovery software. It’s not an option.

Data recovery software for memory cards has been available for at least eight years. There’s absolutely no excuse for not having this business-saving and face-saving software.

If you ever bought a pro memory card from Sandisk or Lexar in the past six years, (and why wouldn’t you have done this?), it came with free recovery software. But note that recovery software has to be kept up-to-date to recognize new raw formats.

Pro-level recovery software is no longer free. But it’s a cheap US $29 from PhotoRescue, which is probably the industry standard.

Today that $29 software saved an $800 job for a photographer. It also saved his reputation which is probably worth a lot more.

 

Advertise You not Them

There are a lot of folks who have either an iPhone or a BlackBerry. I know a couple of photographers in Toronto who carry both: company-issued BlackBerry on one hip and personal iPhone on the other.

If you have one of these devices, and haven’t done this already, you may want to remove the third-party advertising from your e-mails. Unless, of course, you want to brag that you have a new toy. :-)

By default, e-mails sent from an iPhone end with “Sent from my iPhone”. Similarly, e-mails from a BlackBerry end with something like “Sent from my BlackBerry on the Rogers Wireless Network”.

Replace these with a promotion for your business.

Half-full or half-empty

If you weighed a 10-lb bag of potatoes and found that it weighed only 5 lbs, would you be concerned?

If a store clerk said that a 10-lb bag of potatoes weighs 10 lbs only if you buy it in the morning, would you be confused?

Let’s talk about camera flashes, in this case, the Nikon SB-800.

I was shooting a photo today with a Nikon D3 and an SB-800 flash manually set to 1/2-power. Deciding to add more flash, I upped the flash to full power. Surprise! The flash exposure remained the same. What’s going on and where’s my light?
