Metering A White Background


 Metering A White Background

Consider if the subject in the foreground was holding a piece of the white background seamless paper next to their face with only the key and fill lights on. When the exposure for the face was correct the paper would be reproduced as white wouldn't it? Not 255.255.255 blown out white, but something in the range of 240s which makes it look like what it is, a piece of paper not the blazing sun.

Creating a vintage Hollywood portrait

 Creating a vintage Hollywood portrait

An online search and a trip to the library turned up plenty of vintage Hollywood portraits for study. A closer, objective look at the photographs revealed a few surprises. This is a pretty common part of the process for me. You see, I had an image in my head of what a vintage portrait looked like and it was pretty accurate, overall. But the camera angles, in particular, were lower than I would have thought. Eye contact with the camera wasn’t as common as I’d envisioned. Research pays off.

Understanding digital image interpolation

 Understanding digital image interpolation

Image interpolation occurs in all digital photos at some stage-- whether this be in bayer demosaicing or in photo enlargement.  It occurs anytime you resize or remap (distort) your image from one pixel grid to another.  Image resizing is necessary when you need to increase or decrease the total number of pixels, whereas remapping can occur under a wider variety of scenarios: correcting for lens distortion, changing perspective, and rotating an image.

Diffraction in Photography

 Diffraction in Photography

Diffraction is an optical effect which can limit the total resolution of your photography-- no matter how many megapixels your camera may have.  Ordinarily light travels in straight lines through uniform air, however it begins to disperse or "diffract" when squeezed through a small hole (such as your camera's aperture).  This effect is normally negligible, but increases for very small apertures.

 Methods for focusing self portraits

Self-portrait shooters usually rely on the trial-and-error method of focusing. Shoot, shoot, and shoot again until the perfect combination of pose, exposure, and focus are achieved. But there is a better way (several, in fact)! All of these methods are quick and easy and will give you accurate focusing without a lot of frustrating trial and error.
