New to editing software, not sure where to start...
Thanks for letting me know about Aperture and non-destructive editing. It is a superb way of working. The BW conversion I have in mind is quite specific in that you have the ability to click and drag on colours you want lighter or darker. For example, you can click in an area of blue sky and dr...

New to editing software, not sure where to start...
Hi - I'm fairly new to SLR photography, although loving every minute with my K7 and I currently don't have any editing software (beyond the basics in Apple's iPhoto). I don't want to go mad and spend a fortune as I'm also a bit of a purist, but I'm keen to learn more. Can anyone recommend the best s...

shooting through glass
Manual focus, careful lining up to avoid reflections and maybe a polarizing filter.

Something I don't understand about Cokin filters
Hello All I'm currently pricing up a Cokin filter system. Considering I don't have much consistency in filter thread size but do have some large diameter lenses it is a much more cost effective way of getting a comprehensive filter set. For the price of 2 decent polarisers for a 72mm and a 77mm ...

Something I don't understand about Cokin filters
Agree with John. I've done the Cokin filter system and although it's fine for first filter explorations, I'm personally now in the process of replacing it with dedicated filters. One set of very large filters with step downs for your smaller lens filter diameters are a reasonable compromise cost...

Something I don't understand about Cokin filters
I'd pick up a couple of round polarising filters for your most used lenses, and you can always get stepping rings to adapt them for other lenses if need be. Anything Hoya is probably acceptable. I'm not sure if you need the new slim-fit, HD-ready, "it's got electrolytes" versions. I use an old s...

Something I don't understand about Cokin filters
You may have noticed a little square part that pops off on the bottom of your Pentax hoods, with it removed you can rotate your polarising filter, that is its purpose. Shooting into the sun isn't an issue with polarisers since they would have no effect whatsoever, they work when the light source ...

Something I don't understand about Cokin filters
You can't use a lens hood with filter holders, but a lot of people do use them and I think with a little care there is little effect on iq. People use them because there is no way of reproducing the defect without making multiple exposures and pp-ing. Screw in grads don't give you enough control....

Something I don't understand about Cokin filters
Fyi, stacked cokin ND filters are a particular problem for Pentax cameras - Pentax lets in more IR than most systems. By the time you've stacked several, your image becomes magenta. Cokin filters in their own (ie just 1), seem fine. The P and A series indeed have that problem but the Z-pro and the X...

Something I don't understand about Cokin filters
Sounds like sticking to the circular filters is the plan for most applications and then a square set for some graduated NDs. Can probably get away with: Walkabout lens: - polariser - an ND or two Landscape lens: - polariser Tele and macro: - nothing Cokin/square filters: - ND gra...

Something I don't understand about Cokin filters
I probably wouldn't know what to do with any other filters anyway. I've already found out that an infrared filter is useless with the GX20. I get better pics from the old Kodak superzoom I took apart and removed the ir pass filter from. They say that about the K10D to. The problem is there is ...

Something I don't understand about Cokin filters
Hefty, you can test it. Aim the camera at something without a shining surface, so something that shouldn't effect the exposure when you turn the filter and turn the filter. If the exposure change when you turn then it doesn't work with the light meter. Cedric already tested it once with the K10...

Something I don't understand about Cokin filters
If you like using square filters, like Cokin, try some SINGH-RAY filters. They're all good quality glass filters and instead of using a filter-holder, Guffer Tape works excellent (this way you can stack multiple filters in different angles all at the same time). There not cheap by any means, but yo...

new computer for photoshop
I thought graphics cards mainly benefit games and some 3d modeling apps, but apparently with Photoshop cs4 there are some 'GPU-accelerated features that require graphics support for Shader Model 3.0 and OpenGL 2.0'. What this means exactly is a bit unclear to me but I'm sure some users here have mor...

Sharpening technique for photoshop CS2+
I've copied Matt's sharpening method as advised by Stefan but need a quiet two or three hours to ge my head round it! I have a version of Photoshop which was lauched at the Great Exhibition in the 19th century, so up to this point have used either unsharp mask or Gareth's suggestion of two layers...

Bag recommendations/comments?
I'm using a Lowepro Slignshot 200AW and I can fit a vast amount of stuff into it! If I'm not walking great distances it will contain my K20D, 3 large lenses, 2 large flashes, 4 small lenses, and the last two partitions and front pocket full of all the other crap - 3 hard filter cases (77mm), Raynox...

Polarised filters
Point it to a matte wall or object, white paper for example and turn the filter. Since no reflection change, light stays the same but with a linear filter the camera changed the shutterspeed at around 1 stop when set to Av while turning, with circular filter it doesn't changed at all.
