Image upsizing with Topaz Gigapixel AI

If you are making prints, sooner or later you’ll have to upsize the image file. Even with such a basic task, there is much to be gained by using appropriate apps. In this post, the third and last in a series devoted to the Topaz suite of AI-based tools, I examine Topaz Gigapixel AI upsizing […]

Deblurring a film image with AI-based apps

Located north of Arctic Circle, Gates of the Arctic National Park and Preserve is the ultimate wilderness park in the country. Absent any facilities such as trails, signs, or campsites, it is often possible to feel that you are the first human ever to set foot in the park. No roads lead into the park. […]

Pisgah: how to photograph a cave with a single light

Caves open for tours geared towards the general public, such as those found in national parks, generally have paved paths and beautifully installed lights. What sometimes makes them difficult to photograph are restrictions like the prohibition of tripods. Outside of those caves, there is a whole world of undeveloped caves that offer a wild and […]

Topaz Labs Sharpen AI: Deep Learning Comes to the Rescue

How many times have you left a scene convinced that you got the photo “in the box”, only to find out upon looking at the file at 100% on the computer that it was unacceptably blurry? Some photographers advocate making generous use of the digital trash can when images are technically flawed. However, when images […]

Night Landscape Capture and Processing Example

Despite being one of the most spectacular spots on the entire coastline of Acadia National Park, Ravens Nest on the Schoodic Peninsula is a little known and unmarked location. I will elaborate in the next article, which will be a location guide. In this article I discuss how I photographed and processed the image using […]

How to Convert Digital Files for Printing: Step by Step Example of RGB/CYMK Conversion

A main technical obstacle in making great prints from digital files is that you are translating an image viewed through the transmissive vehicle of the computer screen to a physical medium which is reflective. In this article, I explain with examples how to compensate for that difference, using as a step by step an improved […]

Processing tip: Brightening in Lightroom Explained

Brightening an image in Lightroom with sliders looks like a straightforward task, yet there are two ways of doing it, and they can yield very different results, as illustrated with images and stepcharts. This framework is also used to examine the most useful Lightroom slider. Brightening an under-exposed image This image of the White Cliffs […]

Processing Tip: Highlights and Shadows in High Contrast Scenes

In this post, using images from the Black Canyon of the Gunnison for which I had described the location, I demonstrate two of the processing steps I use most frequently for high contrast scenes. Both consist of somehow counter-intuitive, but extremely simple and effective, opposite slider moves. Although this post is illustrated with Adobe Lightroom, […]

Quick Tip: Change Aspect Ratio to Preserve Composition

Amongst the many new controls brought by digital processing, one of the simplest, and most often overlooked, is the possibility to change an image’s aspect ratio. One could do a lot of changes in the darkroom, but altering the aspect ratio by optical means was very difficult. Why would someone want to do that? When […]

Polarizing Filters and Vignetting on a Wide-Angle Lens: Corrections in Processing

Modern zoom lenses are quite amazing compared with what was available a few decades ago. A lens such that the Sony FE 24-105mm f/4 G OSS (reviewed here) offers a great combination of sharpness and versatility in trans-standard focal lengths, all in a relatively compact package – consistent with the appeal of their A7 series […]
