Looking at Lookup Tables (LUTs)

A while ago, I began hearing a term that I wasn’t familar with:  lookup tables (LUTs).  Curious, I “looked up” the definition, and was mildly puzzled to see it defined as a series of values in table format that helps you interpret or translate another set of values.

Image DataWhat does that have to do with photography?  As it turns out, every part of a digital image is a set of values – for size, dimensions, camera settings, colour space, etc.  We’ve long had the ability to manipulate any one value to our liking through the sliders we see in modern editing software.  Now it seems we also have the ability to redefine broad swaths of data at once.  Find out how.

Believe

One of the hardest lessons I’ve had to learn as a photographer is not to limit myself to the immediate reaction I have when looking at a scene or subject.  There is potential in every situation, even those that to the human eye and the camera initially look like disasters.

A friend of mine invited me to join her to try to shoot car light trails from a highway overpass at dusk, achieving both the capture of the sunset and the movement of the cars through light trails.  Here’s what happened. Continue reading “Believe”

In Full Retreat

I’ve been out of touch for a month.  Sorry about that.  I seem to be busier now than when I had a full-time career.  Recently, I had the pleasure of heading out with my photography club to its annual “retreat”.  A chance to immerse myself in all things photographic for a full weekend.  We chose a destination that we could drive to in an afternoon, but also one that would require disconnecting from all the demands back home.  It was wonderful.

Focusing on What’s Important

In my last post, I commented on my distinct lack of enthusiasm for the new mirrorless camera offerings from Nikon.  Subsequently, both Canon and Fuji have also released new mirrorless cameras.  Each one proudly publishes a fancy spec sheet, full of images of the camera bodies, accompanying lenses and their capabilities.  Pages and pages of data.

Mirrorless CamerasIn the past, this would have caused me to breathe more rapidly, excitement building, as I surveyed the options ahead.  Not this time.  Not for any of them.  And I’ve been trying to figure out why. Continue reading “Focusing on What’s Important”

And So The Battle Begins

As most of you know already, Nikon launched its full-frame mirrorless cameras on Aug 23/18, revealing two models that will appeal to both pros and hobbyists alike.  Priced respectively for those markets, the pro model will be available in September and the consumer model in November.

This isn’t a review of that equipment.  You can get a very good overview of the offering in the great article by M. Zhang from Petapixel.Nikon Mirrorless

What struck me as I watched the launch was just how hard Nikon was struggling to differentiate this product from the offerings already out there.  Perhaps it was the English translation, but “redefine possibilities” and “new light…to pioneer the future” left a lot to be desired as to why I would buy this camera over any other.

The Meaning of Life (ok, not quite)

One of the most confusing parts of photo editing for me is finding simple definitions for some of the concepts inherent in photo editing software.  Things like layers, blend modes and opacity, which are concepts many people ask about.  But also the difference between pixel layers, raster layers, adjustment layers, and fill layers.

Featured ImageWhat are filters and why are they separate from adjustments?  And what the heck is rasterizing anyway? Or the difference between “rasters” and “vectors”?  And what is “rendering”?  And of course, the single most important concept – non-destructive vs. destructive editing.

Despite shooting for many years, I stumble my way through explaining these concepts.  So I finally went looking for the real answers.  It wasn’t as easy as I thought it would be.   But I persevered.  Here’s what I found. Continue reading “The Meaning of Life (ok, not quite)”

Most Bizzare Story Ever

It’s the stuff of mystery novels, with twists and turns and a very unexpected ending.  A sculptor in the US was recently awarded more than $3M in damages for copyright infringement over misuse of his work.

WAPO StoryThe work:  a replica of the Statue of Liberty, designed for a casino in Las Vegas.  The culprit:  the US Postal Service, who legitimately licensed a copy of an image taken of the replica by a photographer who offered it on Getty Images.
