How to scan negative film - The Image Quality Professor's Blog

This week the Professor shows you how to easily scan these using your camera and Capture One Pro 8. If you ever need to scan negative film, you should consider using your camera and Capture One Pro 8 to do the job. You only need a tripod, a light box, a macro lens and optimally, a camera that can shoot tethered directly into to Capture One Pro 8. With the Levels tool in Capture One Pro 8 you can easily invert the image and optimize the dynamic range to achieve a perfect reproduction.

Setting The Mood With Low Key Lighting. This image was made using a flash on camera, bounced into an uncoated muslin reflector. The uncoated muslin warms the light up about 400 degrees Kelvin. The reflector was positioned above and to the left of the camera, with the flash aimed into it.

EOS-1D Mark IV, EF 100mm f/2.8L Macro. ISO 100, 1/250, f/4. This diagram shows the lighting for the image above. Last week I wrote about high key portrait lighting and how it creates a very upbeat feel in images lit that way. Light reveals your subject, and shadows define your subject. Indoors, the simplest way to achieve low key lighting is to use a speedlite on camera, bounced off a wall, or into a reflector angled to catch your subject in the face. If you’re able, and want to get the flash off camera, using a wireless trigger on your speedlite, while placing it in a softbox gives you another option to light your subject. Lighting a full length figure, with a natural falloff at the feet.

Sensito du numerique : introduction. La dynamique, point faible du capteur numérique ! Pareillement à la latitude d'exposition du film argentique, la plage dynamique du capteur numérique se lit sur l’axe horizontal, toutefois là entre des limites brusques (non progressives comme en argentique) se rapportant du côté des ombres, à un point de la courbe de réponse caractérisant le niveau de bruit numérique et du côté des hautes lumières, à un autre point marquant le niveau de saturation.

La dynamique, point faible du capteur numérique !

Dans son « encyclopédie » ambitieuse traitant du reflex numérique, René Bouillot note que le bruit, « phénomène produisant des petits points plus ou moins colorés dans les images numériques, surtout visibles dans les zones d’ombre […] se manifeste surtout aux sensibilités élevées ou en pose longue » et « affecte davantage les APN à petit capteur (4) ». Ces deux critères que sont le bruit et la saturation n’étaient pas encore idéals au début de l’ère numérique.

Multi-Pass Sharpening Techniques Using Sharpener Pro 3.0 with Dan Hughes. Wildlife and nature photography - hints and tips - eposing to the right. When shooting slide film, many photographers intentionally under-expose by around 1/3 f-stop in order to saturate colours and prevent highlights blowing.

Wildlife and nature photography - hints and tips - eposing to the right

Slide film is extremely unforgiving of inaccurate exposure and a 1/3 of a stop latitude is about all you will get before your slide ends up in the bin. Digital is much more forgiving in this respect and over/under exposed images can be rescued to a surprising degree - particularly if you shoot in RAW. RAW images have around 1 stop more headroom in the highlights than jpegs.This aspect of digital photography differs radically from film camera technique, so in this tutorial we will explore how to get the very best out of our exposure settings when shooting digital.

In many of his earlier posts, he refers to this technique as panoramic stitching.When I wrote that “Ryan Brenizer invented” this technique, I now realize that invent was the wrong word to use. He no more invented this technique than Columbus discovered America.

Photographe Mariage Nice. 21 jan. Index des Cours Gratuits sur la photographie. Expose Right. On my recent workshop in Iceland (July, 2003) I had a fascinating chat with Thomas Knoll about signal to noise ratios in digital photography. You may recognize Thomas' name — he is the original author of Adobe Photoshop, and also the author of Camera RAW.

(A discussion with Thomas is featured in The Luminous Landscape Video Journal, Issue #6, from the Fall of 2002 when I was reviewing a pre-production Canon EOS-1Ds). But I digress. We spent a lot of time chatting about digital topics during our 3,000 km drive around Iceland, and Thomas elaborated on one that had not occurred to me before, though once I started thinking about it makes perfect sense.

Digital Exposure (Exposing to the Right) Article and Photography by Ron Bigelow www.ronbigelow.com I want to start off by stating that not everyone accepts the information presented in this section on exposure. So, I will present the information and let the reader decide whether or not to utilize this exposure method (I do). Exposure is one of the most basic of photographic skills. Proper exposure allows the photographer to maximize the quality of the image and to determine where detail will appear in an image. In color photography, people often expose for the mid tones.
