Tips for Photographing Children







By Jon Wason copyright 2011
Photographing children can be a challenge but a few simple tips can help you capture some great shots. Children can be hard to photograph because they move quickly. Children also tend to have a short attention span and their mood can change from giggling to crying in two seconds.
The first thing that I recommend when photographing children is to move down to their level because if an adult six feet-tall stands close to a four year-old and shoots a photo of that child most likely the resulting image will be the top of the child’s head. Not a great portrait.
So kneel or sit down and your photographs of children will improve. If you are getting older and your knees can’t take much kneeling; then pull up a chair. You will find yourself closer to eye level with you subjects. Also try moving closer. Some people are always too far from their subject and their images include too much background.

Because little kids run around a lot the photographer has to be ready. Using a flash can stop some of the action. Sports photographers know this. The duration of typical photo strobe is 1/10,000 of a second. Even a sugared up three-year-old does not cover much territory in that short amount of time. Even on a sunny day a flash can improve your photography because mid-day sun tends to created harsh shadows under the eyes, nose and chin. The light of a flash can reduce this problem.
If you are attempting to shoot a formal or semi-formal portrait of a child in a studio setting get the camera and all the equipment set up before the child (or children) are asked to pose. Otherwise the ten minutes or so that they can refrain from running, jumping and playing are wasted as you set the ISO, changes lens and adjust the shutter speed. By the time you are ready to start, they are all done and twitching to get out there and play.





Talented child photographers know how to use props like bubbles, balloons and puppets to get children to look at or at least toward the camera. Babies can be especially challenging since they are just learning to respond to verbal commands. A three-month old cannot understand, “Smile for the camera,” but she will probably look at a red balloon or turn toward a squeaky toy. Be warned that even these new and exciting stimuli will lose their interested after a few times.
What happens if the happy children are uncooperative, bored or crying? I usually try to enlist the help of the parents to get the child to cooperate. But I do not push it too far. I believe that children (and all people) have a limit of how long they can pose for the camera. Even professional models have limits.
Threatening a child to smile or face punishment is not effective but I have witnesses several occasions when a well-meaning parent said something like, “smile or I’ll take away your Gameboy.” It doesn’t bring a smile to the children’s face.
The candid approach is very effective for children. Just let kids be kids and photograph them from a distance. Shoot a lot and delete the ones that did not work out. Also keep practicing. The more you practice the better you will get at photographing children.

Flash Memory is a Marvel of Modern Science

The tiny memory cards that store hundreds of images for digital cameras may look insignificant at a glance but they are amazing. Their storage capacity, the speed at which they write, and their low cost make them a modern marvel. These little rectangular Compact Flash (CF) cards and SecureDigital (SD) cards are silent, have no moving parts and can withstand exposure to magnets, intense pressure and temperature extremes. Even if you accidently drop one in the toilet, it will not be damaged.


The person credited with inventing flash memory is Dr. Fujio Masuoka. In 1984 while working at Toshiba he made major developments in his work with cells that hold data and can be erased rapidly then rewritten. Flash was suggested as an appropriate name for the new type of memory because the process of erasing data from the cells was like a camera’s flash. History was made in 1984, when he presented this new technology at the meeting of the Institute of Electrical and Electronics Engineers (IEEE) in San Jose, CA.
Intel and other companes saw that flash memory had great potential. In 1988 Dr. Eli Harari and Sanjay Mehrotra, former coworkers at Intel, formed a company to produce flash memory for consumers. They founded SanDisk, which is now a world leader in digital memory devices. Sandisk’s launch in Silican Valley was perfectly positioned to take advantage of the the arrival of digital photography.
Some early digital cameras like the Sony Mavica stored images on a floppy disk. People liked this because it was easy to take the floppy out of the camera and insert it into a computer to transfer the images. The next generation of Mavica recorded images to a CD. But flash cards ultimately became the prefered media for digital cameras because they were small, had no moving parts and could be erased again and again.

Flash memory, unlike RAM (Random Access Memory) can continue to store information in the absence of a power source. This made flash memory a good choice not only for use in digital cameras, but also PDAs and video games. As consumer demand for flash cards grew Sandisk, Lexar, Kingston, Samsung and other companies offered Memory sticks, xD, SmartMedia and MultiMedia and other removable flash memory products.
As competition heated up, each brand would advertise higher capacity cards: Attention we have 4 Gigabyte cards! Look 8 GB for sale! Introducing 16 GB! Come and get the amazing 32 GB card! 64 GB cards are here! And as the public purchased the newest memory cards they found that the price paid per GB dropped steadily. That is the good news, but there is also bad news.
Unfortunately, counterfeit CF cards that look authentic but are knockoffs of the big name flash memory cards have appeared. These are passed off as the real thing to bargain hunters who later may find their joy of getting a great deal replaced by the sinking feeling that accompanies the realization that their data is lost.
Overall the invention of flash memory has been a great benefit to photography. So next time you are clicking photos take a moment to appreciate the wonders of modern technology.
