Mac versus PC, RAW versus JPEG, Coke versus Pepsi, all solid battles in their own right but Adobe RGB versus sRGB is still one that confuses more people than anything else. One of the problems is that there is big name experts on both sides of this argument arguring why their side is right and the other is totally off-base. What we will try to do is to show how both affect images so that you can choose the right one for your situation.
Although you may think that no two situations are alike, the fact is that there are quite a few constants that you can rely on to give you a good starting point. The sun is one of these things you can count on to be consistent. Of course there are things that affect the sun’s output like the time of day, haze, fog, and clouds, but on a bright sunny day the light output is very consistent and knowing the camera settings for this condition will give you a guideline to make adjustments. This is where the “sunny 16” rule comes into play.
A big stumbling block for many new camera users is how to figure out how much depth of field a particular image will have it in given the focal length of the lens, the aperture used and the distance to the subject. Trust me on this, trying to do the algebra to figure it out is not something most people want to try to do in their heads. In this article we will cover all of the math involved and then make it real easy with an Excel spreadsheet and some links to some free applications to help you out.
Yes, RAW vs. JPEG, the seemingly endless debate, almost as bad as Mac vs. PC or Film vs. Digital and people have been asking me to write up an article on this based on my opinion and experience and I have really put this article off for a long time as I wanted to be as unbiased in how I write this given that this is a very biased topic.
I have heard the phrase â€œI donâ€™t need no stinking light meterâ€ more times than I can count, your LCD display and histogram are all you need for a perfect exposure right? Would you be surprised if I told you that your camera was lying to you? We first need to know why our LCD and histogram is wrong before we can believe that using a light meter will be of benefit.
