Plenty of filters to purchase both low and high end, but like most things in life you get what you pay forin relation to quality. However if you want to start with the most versatile filter for landscapes I would recommend a circular polarising filter, they can be used to increase colour saturation...

Having learnt the lesson the expensive way myself i would suggest going straight for lee filters, im speaking through experience that the cheaper alternatives are not nearly as good To get started i would recommend a 2 & 3 stop ndgrad a polariser is also an extremely useful filter to have ...

Thanks guys. I have a QP Card for the colour but how would that help with exposure? I also have a Tiffen card somewhere as well. Take the exposure off a grey card. You could use a filter such as the Expodisc but it would mean pointing the camera towards the light source. A handheld incident li...

What's New in Photography?
I think conditions, be they weather or studio and the artists vision should be able to create infinite possibilities. New methods and New locations certainly do not stay New for long. (We've all found ourselves setting off in the car to a place 'cause we saw a shot we liked and wanted our own on...

OK gang, back on topic please. We're not talking here about black and white options with colour sensors, we're talking about doing away with the Bayer filter altogether so the only information being recorded is luminance at each and every pixel. If you did the same thing with a colour filter in plac...

Nikon have been flirting for years with the idea of an interchangeable sensor. I think the worry is that it may cost as much as an entire camera. I think the idea has merit. If you could carry one or two bodies with a 'normal' back, mono back, infra-red back, high ISO back, low ISO back, etc wh...

Ken's discussion is intended to be about having black and white only sensors Of course, it depends on the price. Some reading material on the topic: B&W conversion (panochrome Bayer filter removal): http://www.maxmax.com/b&w_conversion.htm M monochrom: http://www.luminous-landscape.com/r...

I wonder if the increased resolution has more to do with the anti-aliasing filter than the Bayer matrix... ? For example, this company removes the AA filter from the D300: http://www.maxmax.com/nikon_d300hr.htm Nikon now provide the D800 without the AA filter too. Some Googling shows that ot...

I didn't realise that removing the AA filter rendered the images in B&W. I thought the camera with no name has no AA filter and those Nikon images look quite colourful. Are we straying off topic again?

Removing the AA filter removes the slight blurring that is introduced to avoid moire effects. This has nothing to do with colour. It is why all digital images are slightly soft direct from the sensor and some sharpening is needed. The sensor always sees in black and white, the colour being introd...

Just to reiterate... The Bayer filter is there to 'see' in colour. Then the AA has to be added to reduce the effects of moire that are created by using the Bayer filter. With all these options I can see that there could be issues when working in JPG in camera. But anti-moire algorithms are m...

There is absolutely nothing wrong with the term colourise. And I think the results from the new sensor seem to prove the theory that natively capturing a monochrome image is better than capturing a colour image and throwing away information to create a black and white photo. No Bayer filter or AA...

Grad ND advise
Without teaching you to suck eggs I hope that the next few lines will offer some tips and pointers. The ND Grad is used to balance the exposure between bright areas and darker areas. However, you also need to know the difference in stops in relation to the light and dark areas and then use an app...

I don't think I've quite mastered locking the exposure You don't need the camera to your eye to do it, just point it in the direction of the ground and half press the shutter followed by the exposure lock, which you should have no difficulty finding as you can clearly see the back of the camera, you...

Yes, meter for the grass without the grad in place, (it doesn't have to be totally out of the holder) I say meter for the grass but I suppose as long as you keep the sky out of the frame you could try metering from anywhere, it's still not going to guarantee a perfect exposure it's more of a quick ...

Another approach (that might be a touch quicker) would be to use spot metering. Raise the filter so that a clear part is over the centre AF spot, take a reading (and lock it), lower the filter and "Hey Presto"! Results will vary depending on the colour/reflectance of the part of the image that is ...

Thanks guys, I frequently use manual when the camera is on a tripod (I wasn't thinking I suppose). So in a sense it serves me right for not being too critical in the field. Sorry to belabour the metering but, If I meter the grass with the filter out (or at least through the 'thin' bit) the sky...

If I meter the sky through the 'thick' bit anything then seen through the 'thin' bit will be much lighter -- This is were I'm still puzzled as the grass patently wasn't lighter That's because the difference in required exposure between the sky and the ground was not balanced out correctly by either ...

It all sounds a bit complicated to me but am sure the challenge will be fun. I have an old meter and tomorrow I think I'll take readings off the camera, pointed at the lawn then the sky and do the same with the meter to see how they compare. Am I right in thinking the readings should roughly be the ...
