Over the days leading up to the 25th of December I’d like to give something to everyone who stops by my blog. These tips cover camera settings, flash, lighting, software and gear. I’ll be providing a pair of tips each day until 25th December.

#19 – Choosing and using the right colour space

camera colour space

Your camera can create images with one of two different colour spaces. The default is sRGB with AdobeRGB as an option. If you shoot JPEG images, then the choice is fixed in your pictures, if you shoot RAW you can decided when processing the files on your computer. So which should you use?

AdobeRGB offers increased range of colours mostly in the blue and green tones – think sky and grass. sRGB usually handles skin tones slightly better, but there is very little in it. If your client asks for a specific file, deliver that. If you will print from your JPEG on a high quality inkjet printer, then AdobeRGB is usually the best choice for it’s extra headroom in blues and greens. For most online use, sRGB is the best choice as it looks better on non-calibrated screens.

One effect of choosing AdobeRGB on the camera is that the filenames created will have an underscore character as the first character.

app colour space

If you shoot RAW, you need to make the decision when processing your photos. Canon’s DPP software offers five different colour spaces, and if you choose one in the preferences it will be the default for all images, unless you change it on an image by image basis.

Alternatively you can have DPP follow the colour space that was selected in the camera when the photo was taken when you select the checkbox indicated.

 

 


#20 – Keep your lenses clean with Lens Pen

Camera lenses get dusty and dirty, so you need to clean them. There are countless ways of doing this, but I find that for general maintenance the Lens Pen is the most practical solution for me. It’s handy that it drops in to one of the pen pockets in my camera bag, and then is always ready for use. To use the Lens Pen you need to make sure there’s not grit on the lens, and there’s a handy soft brush on one end to gently brush the dust off. Once that’s done a couple of turns of the cap and then you remove the caps to get to the cleaning part. This is simply pressed against the lens and moved over the glass surface.

In my experience it does remove just about all marks I’ve had on my lenses, and over time they are easy to clean if you get in the habit of doing it regularly. I almost never use a protection or UV filter on my lens and the one in the picture is approaching 30 years old. It’s been cleaned with lens cloths in the past, but for the last fifteen plus years only the Lens Pen (Amazon).
