Big square filters (again!)
'Lo all I started a post a while ago asking about filter systems. I was looking into the economical way to get the effects I wanted across all lenses (i.e. cokin-style filters so I could just switch them between lenses). However, following the advice from here I decided to go with circular filt...

Big square filters (again!)
Cokin consist of more systems. The normal ones like the P are decent but the bigger ones like the Z-pro is slightly better. They use better quality glass and they have less off a colour cast. There is also HiTech Formatt filters. From what I hear they are better then the standard Cokin filters b...

Which one would you choose?
We'll I've played with the Mac. I went to the city centre a monday to get a camera filter (you see I'm not so indecisive with everything, it's only computers :?) but they need to ordered it and it was in today and to my surprise found an I'am Store a long the way :) Played with the Mac for a long ...

Infra Red, why bother?
It gives you a very special few of the world and some really are masters in it. When you build your camera to IR you've the advantage that the IR filter is behind the mirror so you can still see normally through the viewfinder to compensate your photo. That's the main reason for doing it I believ...

Polarizing filter for my k-x
Yes it will be 52mm I would recommend the Hoya Pro1 Digital (or the latest version). With polarisers there really is a lot of difference from cheap to expensive - reflections, colour cast, distortion, vignetting as the mount is too thick ...

Polarizing filter for my k-x
The more expensive ones will have a better polarizing effect and give you less colour cast or render them differently. Also the more expensive once have multiple coatings to make them better. Hoya and B+W are considered the best.

Sigma releases SD1 (46Mp)
They're being a bit silly calling it 46MP: it isn't, it's ~15MP. On normal sensors, there is what's called a Bayer pattern filter. To greatly simplify, the sensor only 'sees' the light level. There is then a filter which 'marks' each pixel as being of a particular colour. So for example one pixel...

(I'm not sure about sharpness and other qualities) Bayer filter contributes to softnes, so lack of it in theory may help with sharpness.

Camera bag for holiday
Hi I'm going on holiday in the middle of October and I need a bag for my gear. I'm looking at taking a digital SLR with a medium zoom lens attached and 2 primes. I'm also taking filter holder and filter pouch and also some screw in filters. I was looking at a lowepro flipside 200, the size and sp...

Camera bag for holiday
Hi Dan, I've got the flipside 300 which is a little larger,I really like mine. The gear you have listed would easily fit in the 200, and the 300 would have enough room left for a light lunch and lightweight waterproof. The bottle holder on the outside keeps liquids well away from your gear if ...

Tamrac v Kata
I've used a Kata DR-467 for almost 2 years now. Upon arrival I was suspicious of it's durability and protection because it is very light compared to similar backpacks from other manufacturers and the main straps seemed to have weak stitching where they exit the top of the bag. I can honestly say tha...

White Balance / Colour correction tools
As regards JPEGs, just avoid AWB and use Daylight instead. Then you will record the actual colour of the ambient light. Don't forget to switch off the auto adjustment feature on the K20D and later though. I do any fine adjustments to colour in Photoshop CS2 using Photo Filter, correcting colour j...

White Balance / Colour correction tools
Anything grey will do the job, remote controls, some empty Pentax boxes (£10 off ebay :lol: ) but some are a bit off grey. Get some GREY paint sample cards from Homebase or buy grey card from an artshop. The Kodak Grey card isn't an exact grey anyway. Don't try to WB off white. The RGB for pure w...

White Balance / Colour correction tools
Stefan, I like the Pantone/x-rite stuff and it looks better than just WB alone. The looks good and shows how to balance up the full range of greys. Right from day one video cameras had a button to set the white balance. You just pointed them at what you wanted to balance to and that was it. Pe...

Stefan, I like the Pantone/x-rite stuff and it looks better than just WB alone. The looks good and shows how to balance up the full range of greys. Indeed. What the links shows is the manual way of doing it, with the x-rite software it does that automaticly and save it in form as an profile which...
