Analogue Photography: Part 3 – A Nostalgic Race and a Suburban Shopping Centre with Kodak Tri-X

Polished chrome and proud owners – Jaguar XK120 | Kodak 400TX

Introduction

As promised in my previous analogue articles, “Analogue Photography – A Personal Journey Part 1 and Part 2”, I’ve started shooting with film again and will be sharing the results from each roll in this series.

The pictures you see in this article all come from a single roll of Tri-X, shot at ISO 400 and developed and scanned by bildskanning.com in Sweden.

For the first instalment, I wanted to begin with one of the oldest and most classic black-and-white films available: Kodak Tri-X. It’s a cornerstone of analogue photography, used for generations by renowned photographers. Tri-X first appeared in the 1940s as a sheet film rated at ASA 200, and since 1954 it has been available in 35mm and 120 roll formats at ISO 400.

Understanding F-Numbers and Light Transmission

Introduction

When comparing camera lenses, one of the most commonly discussed features is how “fast” a lens is—usually expressed in terms of f-numbers. But what do those numbers actually mean, and how precise are the differences we talk about, like “half a stop” or “two-thirds of a stop”?
In this article, we’ll unpack how f-numbers relate to light transmission, explore why the system isn’t always as exact as it seems, and show you how to calculate these differences for yourself—or simply reference our handy table at the end.

REVIEW: TTArtisan 35mm F/1.4 Tilt (APS-C)

Introduction

TTArtisan previously released a full-frame 50mm tilt lens, designed to control focus to a thin slice of the scene, or extend it for deeper focus. It’s also fun to experiment with, especially for creating a playful miniature effect. In May 2025, they followed up with an APS-C equivalent: the 35mm f/1.4 tilt lens, offered at a budget-friendly price. Of course, it can also serve as a fast f/1.4 standard lens. Let’s take a closer look!

REVIEW: TTArtisan AF 40mm f/2

TTARTISAN 40mm f/2 on Nikon Z7IIIntroduction

TTArtisan is trying to catch up in the autofocus lens market, having previously focused mainly on manual lenses while other companies gained ground in AF development. Their latest release is a full-frame 40mm f/2 lens—a popular focal length with a bright aperture and an ace up its sleeve: a dedicated aperture ring, something not all AF lenses in this class offer. Let’s take a closer look.

REVIEW: Viltrox AF 15mm F/1.7 Air

Viltrox 15mm f/1.7 Air

Introduction

Viltrox has recently released a couple of small, lightweight lenses in its AIR series, both for full-frame and APS-C cameras. These lenses have generally offered strong optical performance with impressive sharpness at affordable prices. Now, Viltrox has added a wide-angle 15mm lens for APS-C sensors to the series (22.5mm equivalent). This lens is also very lightweight, and at $239, it can still be considered budget-friendly. For the first five days after launch, it comes with a 5% discount — and using the affiliate links provides an additional 5% off*. But is it any good? Let’s find out!
