What price image quality? The rational empiricist response

“What price image quality?” The rational empiricist response Well no self-respecting engineer was ever going to let it rest with that concluding rhetorical flourish! 🙂 Barney kindly provided this addendum to where I left off: “In this post you pose a great question: the file sizes are much larger, but what price image quality? Maybe […]

Post-Processing III – Image File Formats: They Matter

Image File Formats – they matter To come back to the accurate rendering of colours, we need to return to the format in which the image is taken. We can use the same example of the colour space for this purpose, although this time there’s another limitation we want to avoid. Recall earlier that it […]

Post-Processing II – Colour Spaces

Colour Spaces Most cameras are set by default to use a certain ‘colour space’, within which to capture images. That colour space is termed ‘sRGB’ – standard Red, Green & Blue. Bear with me for a moment while this is explained. Imagine this: You’re a painter, and you’ve been commissioned to paint an accurate colour […]

Post-Processing I – Profile your monitor!

Profile your monitor! Now that you have captured the best image/s, it’s time to consider the workflow that will bring out the potential in your work. Note that it would be a rare shot indeed that could not be improved by intervention between camera and posting on a website (or even more so, before printing). […]

Lenses – At the heart of an image

Lenses – At the heart of an image Before proceeding, this would be a good opportunity to review the in-principle material on aspects of lenses. There’s much focus (yes – pun) on cameras. Forgivable for a compact, as you buy into the lens as a fixed part of the camera. Nonetheless, even here it is the lens […]

Choices, Choices…

Still with us? Good effort – keep going when you’re ready! Choices, Choices… Digital cameras are for the most part just another item of consumer electronics. They break down, we break them, we start hankerin’ for the next new best thing since sliced bread… So maybe now or maybe later, you’ll be looking for an […]

A Primer

A Primer To start – a look at some principles to better understand what’s going on when we ‘take pictures’… The elements of photography are in essence unchanged: there’s a light-proof ‘box’, a shutter mechanism that determines how long we let light into that box, and a lens to focus the picture onto a sensor […]

Information about camera bodies and lenses

There are two websites I’ve used extensively for information about camera bodies and lenses, and in the process helped my own understanding of some underpinning concepts: www.dpreview.com contains comprehensive reviews and tests of nearly every digital camera made (including tests of dynamic range, as touched on today). Has some limited lens and other reviews too. […]
