Is Flickr giving away your photography lunch?

Using the new image search function from Google, it looks like my Flickr account is the biggest source of unauthorised use of my images.

I have traditionally used utilities such as Tineye to assist in determining where my images are being used. They do an excellent job of identifying images or portions of an image, but they have not indexed a lot of my photos, despite have a business relationship with Photoshelter who host my image archive.

Google recently released a new image search function which is almost the opposite of Tineye, having indexed a larger percentage of my images,  but their partial image recognition is lacking …. no doubt they have people working on improving this.

To me as a photographer, the perfect match would be if Google purchased Tineye and combined the technologies… major indexing clout, combined with powerful image recognition.

I decided to take the Google image search function for a spin and see what it could do.

One of  the results that struck me most, was a image of the inside of a computer portable hard disk drive posted to Flickr less than one month ago . This image has a Rights Managed (RM) copyright license which has special conditions for offering exclusivity of use, and I know from my records that it has not sold from any of my stock photography sites.

Doing a Google search, I see my image appears on a number of other sites. Visiting each site, I was able to identify the images came from my my Flickr account, as I use slightly different copyright watermarks on each site that I post images.

46 Secrets to Improving your Underwater Photography

I recently received the following question via my website asking for some secrets to improving underwater photography, and as I started to compile the list, I thought that I would share a few of my secrets with you.

…” I just purchased a Canon G12 and the WP-DC34 underwater housing for it. I am an experienced diver, I have decided to get into underwater photography and was amazed by your photos and video with the Canon G12.. I was wondering if you could share some secrets and pointers for my upcoming trip to Belize. I would love to return with some quality video and photos…. hoping your insight could give me an edge. Thanks, Lowell”…..

Thanks Lowell for the great question.

I sat down and started to make a list. It got quite long (some people have written whole books on this subject), so I have tried not to get too carried away.

Some of these secrets are scattered around in previous posts, and I have tried to keep my list to a few key points. Some points relate specifically to the Canon Powershot G12 (which I also own), but most points are general and relate to all cameras that can be used for underwater photography.

Before the Dive

My list starts before the dive, as I am a big believer in preparing things correctly allows you to be more relaxed during the dive, which in turn allows you to take better pictures.

My obsession with preparing and cleaning my underwater housing and lens

Continually concerned with underwater housing leaks, and having experienced a number of images and videos ruined by dust or other material on the lenses, I border on obsessive when preparing and cleaning my underwater housing lens.

Underwater housing lenses suffer the usual problems of dust and lint, but are also susceptible to things like sunscreen (my pet hate), salt residue, sand and other nasties.

Whenever I travel through Cairns, I always stop in to visit the friendly staff at  Digital Diver and pick up cleaning accessories.

Preparation Tips

I follow a set procedure each time for housing preparation:-

  1. Remove the main o-ring and use a lint-free cloth to wipe around the o-ring groove, removing any excess silicon, sand or hair that may have lodged in the groove. A piece of hair or sand under the o-ring can cause the housing to leak. (Tip:- use a plastic credit card to remove the o-ring so you do not damage it. I use my cert card as a reminder for me to take it diving).
  2. Use a second lint-free lens cleaning cloth on the inside and outside of the underwater housing lens to remove dust, lint or finger marks.
  3. Unfortunately cloths can adsorb oils and spread them around. My new favourite cleaning accessory is lens cleaning tissue paper. lens cleaning tissue Continue reading My obsession with preparing and cleaning my underwater housing and lens

Which Canon Powershot to buy for underwater photography – G10, G11 or G12?

An email received today asked for my advice on choosing a Canon Powershot G10 or G11 for underwater photography. There are a number of things to take into account, so I thought I would cover a few in a post.

I received the following email enquiry today:-

“Carl, Please counsel with me on a camera purchase. I am putting together an underwater system and wish to use the Canon G10 or G11. I will get the Canon underwater case. Should I get a near new G10 (ie. from Craigslist – approx. $450 US) or get the G11. Please advise. Thanks! Darrell”

Thanks to Darrell for the question.

I am a keen user of the Canon Powershot G Series cameras for underwater photography, and have owned a G10 and G11 camera.

The G10 vs G11

The G10 and G11 are both good cameras and popular with many professional photographers. There are a few new functions in the G11, but the fundamental differences are:-

  • G10 has 15MP sensor, G11 has 10 MP sensor.
  • G10 has a flat screen back, G11 has a flip screen back.

The smaller sensor on the G11 provides better in-camera noise performance (see my previous post Noise Comparison – Canon Powershot G11 vs G10). I find noise can become an issue underwater, particularly when you are going deeper where there is less natural light.

Using an external flash or video light helps to keep the shutter speeds fast at those deeper depths, reducing noise.

Noise is also becoming less of a problem in post processing. Particularly if you are using Adobe Lightroom 3 with its new software engine, which is doing incredible things with noise reduction. (I have to regularly stop myself going back to old images and improving the noise, as I would never get anything else done.)

I also like the G11 flip screen for taking pictures from different angles, but in the underwater housing it does not make any difference.
