New Topic

NUMBERS


I have so many different ideas on how to approach this topic. Can't wait to see how everyone else interprets it.

As always, if there are any suggestions for topics leave a comment or e-mail me. It has also been suggested to have more topics to help get more out of your DSLR. If there is anything you want to learn or practice with your camera, we can work on that for a fortnight too. Also, feel free to post questions or discussions about photography, techniques, lenses...anything!


**For those who shoot AUTO....get your camera, switch it to Av mode & never go back to auto :) we will eventually get you using full manuel mode. Challenge for this fortnights photos – Shoot using aperture priority (A or Av mode). This allows you to set the aperture YOU want to use & the camera automatically chooses the shutter speed to get a “correct” exposure. (A small number eg. F2.8 means the aperture is opened wider, lets in more light, and also create a shallower depth of field…less in focus before & beyond the point of focus. When you stop the aperture down, you dial in a larger number eg. f11, but the aperture opening is getting smaller, letting in less light….so the shutter speed would slow down to let in more light.

This week play with different aperture settings. You can always use the exposure compensation if you want to overexpose or underexpose the shot (if you don’t like how the camera has exposed the shot with the chosen shutter speed:) Make sense??


Here are 2 examples of different apertures on the same photo. The focus point on both these shots are on the purple 0. I also used a tripod because of the slow shutter speeds.

Wow, I have beem out of it for a couple of months. I tried to do the shadows topic. I tried to take some 'moon shadows' when it was a full moon. When to bed and could see all the great shadows out of the window, so got up and took the camera outside. Clouds came across the moon and that was that :(
Anyway, I would like to ask a question ... I really liked the old towns that I drove through last November on my way to my sisters. The only trouble was, it was always midday as I drove through and the sun was very harsh and the shadows on the verandahs of the town that I was trying to photograph were extremely dark in comparison. How do you take good photos in the glare of midday or when the sun is bright and high?

I definitely want some DSLR advice but don't really know what I need to know to stop just using auto all the time. I am waiting until we move home so I can have lessons with Emma!

Good question Helen (hehe) I usually avoid taking photos at midday, especially when there are no clouds... I will do a post on this later, as I'm sure there are tips about shooting in harsh sun.

Bindi - DONT SHOOT IN AUTO!! :D I will put up a challenge for this weeks topic for anyone else who shoots in auto. Just start off practicing with semi-auto modes...either aperture priority or shutter speed priority :) I'll update the new topic now....

Helen: Lens hood? (Do they work) Find a shady spot?

I was just talking to kalista today about how I used to try and use the A and S and P modes more but now I just tend to use landscape, sport, and portrait (to avoid a flash) in the auto modes (to get the same kind of effect?) because I take photos of my kids mostly and I need to be quick. Sometimes I just don't have time to set stuff up. Do you find that Emma or do you just get faster and get to know your aperture numbers better with more practice? I like the idea of doing tips like this along with topics. Sorry I have been slack. I will try harder now we are into a new year :)

OK. Just set my camera to 'A' and am determined to leave it there for the rest of the week. Will experiment in the next couple of days and let you know how I go. Thanks Emma.

It just dawned on me that you've used the number theme in taking these! I'm so thick! I know it's just an example shot but I love how the top one is perfectly graded from sharp to blur.
