Podcast 218 : Oct '09 Assignment - Only 50mm! - Results

Prefer to listen? There’s an audio player at the bottom of the post.

Today we look at the results of the October MBP/WebSpy Assignment on the theme Only 50mm! We have some great back-stories to share too!

Once again, the quality of the entries for this assignment was outstanding. Thanks to everyone that participated! As has now become the custom, I’ve got three great back-stories from the winning photographers to share with you today.

Let’s start with the third place winner and that is Marcus Bain with image m14607 (below), entitled “Calm after the storm.” Marcus was placed in the August assignment too, and the next two winners were winners have also been placed a number of times already, so we are certainly seeing some consistency here.

Last month I tried to rewrite the back-stories so that I could tell them myself, but I’m going to [...]

Podcast 217 : Photography Fundamentals for the Beginner - Part 2

Prefer to listen? There’s an audio player at the bottom of the post.

last week we started this two part series to update a 5 year old forum post on the fundamentals of photography, which was revived by Chua Kim You, from Montreal, Canada. Thanks again Chua for reviving that thread, and I hope you are enjoying these Podcasts.

If you are just tuning in, and didn’t catch the first episode, it’s not essential to listen to these in order, but if you are really just starting out, and looking for some basic tips, we will be building on last week, so it might be better to go back to Episode 216 first.

It turns out that once again, as I prepared for this week, I ended up writing about twice as much as I can fit in one week’s episode. We’re going to finish up the basics series with this, but I’ll [...]

An Exercise in Magnification with Extension Tubes

Extension tubes are really handy. Because they have no glass elements, they aren’t very heavy, and you can couple two or three together and put them into one pouch, and they are no bigger than a small lens, so they fit in the photographer’s vest without taking up much room.

When you put an extension tube between the lens and the camera, your focus distance decreases, so you can focus on things closer than you would be able to without the tube. The caveat is that they also reduce the maximum focus distance, so once fitted, you can no longer focus on infinity.  The wider the lens, the more drastic the change in focus distance. With wide angle lenses, you almost touch your subject before you get it in focus. It can give you some fun effects, but not that practical. Tubes work best with 50 to 100mm lenses, or even [...]

Podcast 216 : Photography Fundamentals for the Beginner - Part 1

Prefer to listen? There’s an audio player at the bottom of the post.

Last week, a new user on the forums, Chua Kim You, user name redpandafire from Montreal, Canada, revived an old thread from June 2004. I’d posted and article called “Fundamental Advice for Photographer’s Getting Started”. I had to admit, that looking back at this post from over five years ago, there were a lot of things that I would have written differently. The article itself is a little presumptuous and I would have worded much of it differently now than I did back then, but I as a photographer have also changed a lot over the last five years, and so I decided to sit down and think about how I would write this today, and that is the topic of today’s post and podcast. In fact, this is just part 1. I’m going [...]

Podcast 132 : Depth-of-Field Explained

This Podcast was originally released on the 12 Apr, 2008.

Prefer to listen? There’s an audio player at the bottom of the post.

I’ve rarely seen an easy to understand explanation of how the aperture and distance to the subject affects the depth-of-field in our images. When I started to think about how I would explain this, I started to understand why, because it wasn’t easy to do this in a simply way, and I still am not sure if I’ve succeeded. I’m sure you’ll let me know. Anyway, I’ve created six diagrams to help me explain this. I’ve not attempted to draw scientifically accurate diagrams, rather just created them in Microsoft Word to help me explain more easily with words. So let’s jump right into it and attack what should be a very simple subject, though it never seems to be.

I’ve included the diagrams below, but I also published a rough [...]
