All Day I Dream About Photography

Canon users don’t blame your LCD

I’ve been a Canon user ever since my first DSLR and one of the things that always frustrated me is the uselessness of the LCD to evaluate the sharpness of your pictures.

In fact on the back LCD if you try to zoom while reviewing a picture it will quickly becomes pixelated and blurry. No need to tell you my deception when I was trying a friend’s Nikon and noticed the picture was perfect even after a 10x zoom and he could easily check if it was sharp or not.

Sensor dust: Cause prevention is better than cure

Sensor dust is probably one of the worst nightmares of DSLR owners. Manufactures are trying hard to solve this problem with the introduction of “auto sensor cleaning” features in the newest bodies like the Canon EOS 40D or 450D.
Sensor dust will show in pictures as dark spots that will appear constantly at the same place and will be more pronounced at small apertures.

As of today there is no “dust free” solution for DSLR cameras yet, the sensor will accumulate dust over time and you can either learn to live with it or clean it regularly, however some precautions could considerably reduce this problem.

13 of the best flickr silhouette pictures

By definition a silhouette picture is an image where a dark foreground is outlined against a lighter background.
This type of photography is usually achieved by placing your subject in a bright scene and let your camera meter for the background e.g. A person at sunset. The resulting image will be a black, usually without details, focal point that is outlined in a well exposed scene.

For your inspiration and pleasure here is a collection of 13 of the best silhouette pictures that can be found at flickr under the Creative Common License.

A guide to Aurora photography

This is a guest post written by Bud Kunzeli, Bud lives in Alaska and have been shooting Northen lights for years. He was kind enough to write this essay highlighting the most important aspect of Aurora Photography. Bud’s work can be viewed at http://www.pbase.com/santa

There are very few people who have more opportunity to view Northern Lights than those of us living in Central and Northern Alaska. I shoot the lights. A lot. I shoot for 6 hours or more some nights. Some nights they are out 5 minutes. Other nights, 5 hours. Sometimes it’s chilly.

Polarizer: Another must have filter !

I have previously categorized the Neutral Density filter as a “must have filter for any landscape photographer lover. And the reason was that it is one of the rare filters which effect cannot be reproduced in the digital darkroom.

Polarizers would be the other filters fitting that description.

What does a Polarizer do?

Why I never bought a ND Grad filter

Photo by BlueJeff
Earlier this month I have described the Neutral Density Filters as being a must have tool for any landscape photographer, and I was not surprised at all when I got comments that if Neutral Density Filters are important for landscape photography Graduated ND filters should be even more important.
So why didn’t I ever invested in one ?

Why are white lenses … white ?

Photo by seekyu
God knows how many times I’ve read this question in photography equipment forums “Why are most Canon L lenses white?” or “Can’t Canon give me a black L lens?” etc…

Well first of all there are quite few Canon L lenses that are black and second Canon is not the only manufacturer that “offers” white lenses. Lenses are white for a reason.

Why Lenses are white?

Neutral Density Filters: What are they & when to use them ?

Photo by tico_bassie
A few days ago I was shooting when someone passing by stopped to ask me “what are all these pieces of glass you put in front of the lens?” ”¹” so this got me thinking that maybe some of adidap’s readers are not familiar with filters either! So today I will be writing about Neutral Density Filters, aka ND Filters, not to be confused with Graduated Neutral Density filters, or ND Grad filters ”²”.

Exposed: The memory card and ISO affair

Micheal wrote:
Hello,

I hope you can help me I am wondering about the relation between ISO and file size… I have noticed that when I set my camera to a higher ISO I can fit less pictures on it can you explain why ?

Good question Micheal, I will do my best to explain it and I am sure that others will also include their thoughts and input here so you should get a pretty complete answer.

Since you have noticed that higher ISO will generally give you larger files, I think that you might have also observed that a picture file size will vary even at a fixed ISO.
