Some Christmas cheer



WHAT

This shot was taken on Christmas day at my mum's house where my family had Christmas dinner together. It depicts some of the table settings and decorations my mum had laid out.
I took a bunch of photos that day of the family and other objects in the room but I felt this one turned out the best.


WHY
I've mentioned in a previous blog post: http://kylietphotography.blogspot.com/2010/12/race-day.html the importance of capturing the little things that really MAKE a special day what it is- things such as table decorations, food, table settings and the little touches people have added. Hence why I opted to take this photo.

There were other table settings available to use for this shot, but because this one was on a corner it meant I could easily move around the table till I found an angle I was happy with. I also liked how the golden bon bons in the background were arranged at right angles to each other from this position.
As it turned out, I ended up sitting at this very table setting later on for our big meal!

HOW
Because I was indoors and there was very little ambient light coming in from the windows (it was a miserable rainy day outside), I used a tripod for this shot. Using a tripod was another reason I selected this particular place setting to shoot- it meant I could actually fit the tripod in without having to move too much furniture. A tripod also ensured I could keep the ISO down low (200) to avoid a grainy shot.

I shot in manual mode and adjusted the shutter speed until it was at an apprpriate speed as determined by the camera's light metre. This turned out to be 1/5s.

I used a short aperture of f/5 to make the items beyond my main subject blurry to really focus on santa - otherwise I risked losing him amongst all the other stuff on the table. Plus I like the blurry background effect.

POST-PRODUCTION
In photoshop I increased the clarity, adjusted the black levels, and increased the highlights.

Why it's important to continually check camera settings

A few days ago I went to the Springbrook National Park which is a beautiful rainforest filled with wildlife and waterfalls located in the hinterland of the Gold Coast, Queensland, Australia.

As I was taking photo after photo of what I hoped would be great waterfall shots, I happened to glance at the ISO setting and saw that it was set to 1600 – far and above my intended setting of ISO 200! I had no idea for how long it had been set to 1600 or how many of my shots were now going to appear slightly grainy due to the high ISO.

I definitely didn’t deliberately set the camera to ISO 1600. I’m assuming it happened with an accidental press of the ISO button prior to winding one of the dials with the intent of adjusting the shutter speed or aperture. Therefore, while I thought I was changing one thing, I was actually cranking up the ISO. Curses!

Incidents like the one above have reminded me how important it is to check and re-check the camera settings throughout the day/session.


Here’s a list of the things I’ll be checking and re-checking from now on:

The mode I’m shooting in – is it manual, aperture priority or shutter priority? This of course depends on what is important in each shot – depth of field or capturing motion (frozen vs fluid). I’m often switching between modes during my photography outings depending on the subject I’m shooting so it’s good to always be aware of what the camera is set to each time.

ISO setting. To prevent a repeat of the above!

Cleanliness of the lens. At another waterfall photography outing, I was shooting from inside a dark cavern/cave and failed to notice the misty spray accumulating on my lens during some long exposures. This resulted in many of the shots from that day being utterly useless.

Aperture. As stated above- if I’ve decided that depth of field is important, I have to decide HOW MUCH depth I want. It’s much easier to blur the background (by increasing the size of the aperture) at the time of taking the photo than to do so in post-production. Similarly, if I want all of that lovely landscape shot to be in focus, it pays to check I have selected the correct aperture.

Exposure level (ie shutter speed). If I’m capturing the motion of a scene such as a waterfall or a bunch of passing cyclists, I have to decide if I want it sharp (fast shutter) or blurry (slow shutter). The available light usually also plays a part in what shutter speed is used.
