Dust in Sensor

In one of my recent trips I have end up having some dust in my sensor and my attempts to clean this had caused more damage than help. I tried the local canon service center but they would not help as my EOS 350 D is too old and is no longer supported. The only option that seems left out for me is to go for a new camera. I also visited the canon store to check out some new camera, I liked Canon 5D MarkIII and Canon 6D but this is going to burn a huge hole in my pocket. I am sure this is not only going... continue reading

Olympus OM-D E-M5 Review

If you follow my blogs and forum posts, you know I've long been a fan of the Micro Four Thirds system.I'm a firm believer that for most photos or end uses we have reached a point where full frame cameras are an unnecessary expense (each to their own, of course!).I've been putting my Canon dSLR and micro four thirds bodies to the test over the last few months and they come out very close.There were a few things keeping me from fully committing, however.The Olympus E-M5, released in the last... continue reading

Lesson number 1: how to buy a camera body

When I bought my first SLR camera, I had absolutely no idea how it really worked and what to do with it. I soon worked out that just pointing an expensive lens at something and pressing a button did not automatically generate a work of art. This was a major blow for me, as I am fairly lazy and like things to work out first time. However I persevered and with time, I got to grips with my camera.The main obstacles I faced were the huge choice and range of equipment and a lack of some of the very... continue reading

Sensor size

Some of us pay more attention to aspect ratio than others.Some prefer to shoot at the camera's native aspect ratio and crop later while others prefer to compose in the final aspect ratio.At least that is what we have been telling ourselves since the dSLRs we're used to only have one option :)One of the things I love about my Panasonic GH2 is the ability to view and compose in the final aspect ratio, including square![An interesting side note is that I occasionally find myself still rotating the camera into 'portrait' orientation when I'm shooting in square format - which says something about how much my years of shooting 3:2 aspect has influenced my habits...]... continue reading

Is the lowest ISO the best?

I have to admit that when it comes to ISO, I've always assumed that the base ISO was going to have the cleanest output.I had read articles on how some models of cameras were noisier at the 'in-between' ISOs (ISO 125 and 160) than the base numbers (100, 200, 400).This was true on a camera I had a while back, so I didn't really give it another thought.I read an article in a magazine (link here) where someone took a Canon 7D with a lens cap on and compared the noise with the levels boosted up.... continue reading

How to check your camera sensor for the presense of dust.

My technique to check my camera sensor for the presence of dust.Pre-requisites1. A white paper sheet.Steps1. Set the white sheet on a table.2. Mark a black spot(with a marker) on the sheet.3.

Observe the picture, if it contains random black dots other than thedot on the sheet, it means that there is dust on the camera sensor or the mirror... continue reading

Diffraction Limited?

I've been looking into a new body and have decided not to go with the latest Canon 50D.I'm turned off by the high file size, but also because we seem to be getting into territory where more megapixels are making some things worse.While I haven't tried either the 50D or 40D for any length of time, and am therefore not qualified at all to talk about ultimate image quality, I did encounter a few discussions on diffraction, and the impact of smaller pixels.As someone who shot film pre-digital,... continue reading

Lightroom Vibrancy

Vibrancy is a nifty little image processing utility that is available, as far as I know, only in Adobe(R) Photoshop(R) Lightroom(R).This image would not be possible without it.It is an image of a stained glass door of a shop. It was taken from the outside, but as the interior of the shop was not bright enough, it actually looked just greyish from outside the shop.Nonetheless the camera' sensor was sensitive enough to discriminate these faint colours and captured some data, but that was... continue reading
