How to Properly Calibrate Dell U2413 / U2713H / U3014 Monitors

Dell U2413

After we published our article on 10 bit per channel workflow, our readers requested to provide information on how to calibrate monitors with a built-in Look-Up Table (LUT). Specifically, a number of our readers asked to provide a detailed guide on how to properly calibrate the Dell U2413, U2713H and U3014 monitors, which we have recommended a number of times before due to their affordable price, attractive features and superb color reproduction for photography needs. Historically, true 10-bit and higher monitors with hardware LUT capabilities were extremely expensive, making them only attractive to those with large budgets. With the introduction of sub-$500 monitors featuring professional-grade IPS panels (read our article on best monitors for photography to understand IPS terminology), those with tighter budgets are now seriously considering such monitors for photography work. Unfortunately, many end up even more confused after acquiring such tools due to questions related to proper monitor calibration.

Lens Calibration Explained

Lens Calibration Explained

If you are wondering about how to calibrate lenses, this article has detailed explanations and different methods of AF fine tuning. Due to the nature of the phase detect autofocus system that is present on all SLR cameras, both cameras and lenses must be properly calibrated by manufacturers in order to yield sharp images. Various factors such as manufacturer defects, sample variation, insufficient quality assurance testing/tuning and improper shipping and handling can all negatively impact autofocus precision. A lot of photographers get frustrated after spending thousands of dollars on camera equipment and not being able to get anything in focus. After receiving a number of emails from our readers requesting help on how to calibrate lenses, I decided to write this tutorial on ways to properly fine tune focus on cameras and lenses. Lens calibration is a complex topic for many, so my goal is to make this guide as simple as possible, so that you could manage the process by yourself, while fully understanding the entire process. In addition, I strongly recommend to follow these tips every time you purchase a camera or a lens in order to identify and address any potential focusing issues. But I have to warn you – this article is NOT for beginners. If you just got your first DSLR, you might get very quickly frustrated with the calibration process.

How to Quickly Test Your DSLR for Autofocus Issues

Nikon D800 Focus Test

Below is the easiest and quickest way to test if your DSLR has an autofocus issue, along with a recommendation on what to do if there is a problem. This test can be used to detect front focus or back focus issues with a particular lens or a camera body. I will be using the Nikon D800E as a reference camera for this article, but any modern DSLR with Live View capability can be used for the same test (even entry-level DSLRs such as the Nikon D3200 have a Live View mode). Why would you want to test your camera for autofocus issues? Because if your camera or your lenses are defective or have a calibration problem, then you will not be able to obtain critically sharp images.

How to Calibrate Your Monitor

Display Color Calibration

Color calibration should definitely be an essential part of every photographer’s workflow. Otherwise, it is impossible to tell whether the colors that are displayed by your monitor are truly accurate and whether what you see will match the print. There are many ways to do it and the process can be fairly simple or very complex, depending on how accurate you want to reproduce the colors and whether you are also printing your work in-house. The simple method involves free and commercial tools for color profiling LCD / CRT monitors for everyday photo editing and image viewing, and there is also an end-to-end professional-grade color profiling that requires very concise calibration of all display and output devices (such as printers). In this article on how to calibrate your monitor, I will only focus on simple methods to make your monitor show more or less accurate colors, so that you could rely on it for everyday photography needs.
