Mastering Night Photography – Focusing

February 15th, 2015

A lot of people are doing nighttime photography these days including yours truly. There are many good sources of information on nighttime photography. I’ve written a few blog posts myself (Exciting Nighttime Photography in 10 Easy Steps). Nighttime photography falls into two categories – star trails and night sky. In this post I want to elaborate on something I’ve discovered recently with regards to night sky photography.

Mastering Sharpness – Fuzzy Photos

May 2nd, 2014

How many times have you returned from a shoot with some photographs you are really excited about only to find out they are out of focus.  That’s always very disappointing and often frustrating.  And it happens all too often to me.  At the Joshua Tree Gathering this past March someone asked the question, ”How many ways can a photograph be out of focus,” and that got me thinking.  This would be a fun article to write.

But let’s get something straight from the start.  Not all ‘out of focus’ photographs are out of focus.  They may not be sharp but that can come from two causes.  They can actually be out of focus or they can be blurry.  This may seem like a subtle distinction but it’s an important one.  So let’s take them one by one and explore their causes and solutions.

But before we do, I want to make another very important point.  A photograph that is out of focus or blurry is not always a bad thing.  Often times the artist does it intentionally because that is his or her artistic vision.  When it’s done intentionally to create an expressive photograph then it’s not only OK, it’s necessary.  It’s when it’s unintentional that we get frustrated and loose great moments.

But now, let’s get into the details.  We’ll talk about blurs first.

Mastering Sharpness – Depth of Field

March 2nd, 2014

A topic that receives a lot of attention in our workshops is focus.  It’s incredibly important, so important that I consider Appropriate Sharpness to be one of the four pillars of a successful landscape photograph.  (For more, read Making a Photograph – The Four Pillars.)  Most of the questions center around depth of field and hyperfocal distance.  In fact, this is so important that I give a class on Appropriate Sharpness during just about every workshop.  Let’s start the discussion with Depth of Field

Depth of Field

This is the range, if you will, of objects in the view of your camera that are in focus.  Objects in front of this range are out of focus as well as objects behind the range.  A deep depth of field would have the flowers just a few feet from you camera and the distant mounts miles away all in focus.  The depth of field would then extend from a couple of feet to infinity and for all practical purposes would be infinitely deep.  This is often referred to as a ‘near-far composition.’

Making a Photograph – The Four Pillars

May 20th, 2012

I’ve been giving a lot of thought recently to what goes in to making a great landscape photograph. It turns out there are four things, four pillars if you will.  Four, that’s a good number.  There are the four legs of a table or the four wheels of a car.  And not to forget the four sacred directions of the Native Americans.

In landscape photography the four pillars are evenly divided between the aesthetics and the technical.  So what are they?  The two aesthetic pillars are Fantastic Light and Strong Composition.  No surprise there.  The two technical pillars are Appropriate Sharpness and Optimum Exposure.  No surprise there either.  If just one of those pillars is missing, well, the table collapses, the image suffers.

Let’s look at them one by one….
