Introduction, Raw Scans, Neg Film, Highlight Compression, Slide Film, PhotoShop, Conclusion (updated 7 Mar 2013) Introduction Some time ago I wrote an article about getting the most from colour negative scans with VueScan.
Since writing the article my workflow has changed significantly, and these are the main reasons why: It takes far too long to profile the film base colour using VueScan, scanning isn’t fun at the best of times and I’m an impatient person.I’m now shooting a lot more colour slide film, and wanted something that would work equally well if I needed to tweak colour.I’m shooting 8×10 & 4×5 sheet film which doesn’t have an area of clear base that I can sample.I realised that the old method didn’t stop me having to tweak colour in PhotoShop, and that often the output was worse than from a film preset.

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.

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. 1) Why Calibrate? Why is there a need to calibrate lenses? 2) Camera vs Lens Calibration 3) How Calibration Works 4) Calibration Naming Convention. How to Quickly Test Your DSLR for Autofocus Issues. 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. 1) What You Will Need For this test, you will need the following: Any DSLR with Live View mode capability such as the Nikon D7000.At least one lens, but preferably 2-3 lenses if you want to isolate the problem to the camera or your lenses.A good stable tripod.A flat vertical surface in a very brightly lit area. 2) Set Up.

Imagine an exposure computer so advanced that it uses your eyes as a sensor. The processing unit is as powerful as your brain. The computer is accurate over a light range from reflected starlight through the light produced in a hydrogen fusion reaction. This computer weighs nothing and operates without batteries. It comes with instructions to allow you to implant the capabilities of the computer directly into your own memory so you can accurately judge a correct exposure by simply looking at the type of light that the subject is in.
You are using this computer right now! Everything I've said above is true. However, I'm sure you've noticed that the only thing before your eyes is a World Wide Web page.

K20D deleted all—not 1. Of course it was while on vacation that a big problem made me remember the value of mental pictures — even to photographers. By an evening fire I passed around my K20D for all to see on its LCD the last days' shots of a pair of Bald Eagles and 100 other wonders of Nature from the Endless Mountains of north-central Pennsylvania. Before crawling into my sleeping bag, I deleted one poor shot. Instead of the quick flash of the orange light indicator of a deletion, the light continued flashing and the camera showed repeated DELETING — not typical of getting rid of one image. The oddness of it made me try to stop it, but I could not interrupt it. The dysfunction emptied the 8GB card.
The next day as I carefully rechecked every shot, another new problem developed: Though all images showed for a moment on the LCD after being shot, when I reviewed them later, some came up with error message "CAMERA CANNOT DISPLAY IMAGE. " I was very careful the rest of the trip. Since then, no more problems. Digital image recovery - ZAR usage demo. Recover Images from a Damaged SD card.
