polarizing filters and color saturation
hey, im kind of new to all this photography and am still on an ever rising learning curve. i recently purchased a polarizing filter in the hope that the colors would appear like they do through a set of quality sunglasses. through the viewfinder all the colors appear much more sharp and clear......

polarizing filters and color saturation
Perhaps a sample would help. I've never experienced a "dull and grainy" photo caused by a polarizer. The polarizing might have no effect is the light is at the wrong angle to the filter or the colors are more intense with glare reduced.

polarizing filters and color saturation
There are two types of polariser, linear and circular. You will need a circular polariser for use with autofocus cameras as the linear type upsets the autofocus system. I don't know if some exposure metering systems can also be affected. In any event, TTL exposure should be fine but a separate me...

Filters for B/W
In practical terms I would still use a red filter for most of my monochrome work even with C41 process films. I think the main drawback is that the image is made up of dyes instead of silver and it lacks the absolute "sparkle" that you can get with the silver-rich films such as Plus-X, Tri-X, FP4...

Filters for B/W
Hi Kim I didn't really answer the question, did I? As far as I can recall from the last time I used the chromogenic films, the filter effects are similar to conventional films.

Cheap medium format- which one and how?
Just to expand on Matt's comments, the Rolleiflex is a fixed lens camera (75mm or 80mm), although Mutar lenses that bayonet into the filter rings can be used to alter the focal length. These are rare and very, very expensive. There is a Wide Angle Rollei with 55mm lenses (£3000 new, maybe £1500 used...

Nature Pictures-Help
Hi Bobby, The foggy looking water is created by the motion of the water during the exposure. It is created by keeping the shutter open for a period of time, for example 1/4 second to 3 seconds. This is just a guideline and should not be taken as the absolute truth...experiment. You will also n...

eBay listings
Someone has put up an SMC-F autofocus 50mm/f1.7 up: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=15240&item=3872161844&rd=1 (I have this lens, and it's razor sharp, especially with an HMC Pro 1 UV filter on ;) )

Some thoughts on Hoods
Hi, A recent thread on hoods started me thinking about something new. Now I know a 50mm "std" lens has an apparent focal length of 50mm and this doesn't alter regardless of which camera it is used on. According to the Pentax literature, it has a field of view of 47 degrees. This is assuming you ...

Some thoughts on Hoods
Kim is quite right that a tighter hood would work with the 18-35 on the D/DS. However, I think JR is also right in saying that it probably doesn't make much difference in practice. I personally have shot pictures straight into the evening sun with this lens, and seen no ill-effects whatever. No...

Beginning of the end for 35mm?
I understand they are also very good for infra-red photography, using the R72 filter, as they are quite sensitive to IR light.

Camera straps.
My lens hood has another convenient little piece of plastic to loose. The pop out bit so that you can use a polariser filter. Now that is odds on favourite to get lost soon. ( I do not have a polariser, but I am sure that I will loose the plastic bit any way) ps the eye piece tends to have a ...

Extension Tubes, Bellows and Macro Lenses
Kim C.'s manuals have provuded extensive information on the use of Extension Tubes and Bellows with M42 bodies and the Takumar family of "Normal" lenses. He was trying to head off my usual silly questions, but here's a few that slipped through Kim's excellent defence perimeter. I've had no experi...

The Bare Bones
I wandered out for an hour or so last week shooting some film for a change. I just had a Z1p, Tokina ATX-Pro 20-35mm F2.8, a 50mm F1.2 and a Cokin red filter (I was shooting B&W). It made a nice change from shooting digital but I am missing the instant review of results. I wandered about Edin...

confusion about filters...
Thanks Matt. I'm thinking about buying : The COKIN Modular Bellows is a unique, flexible and self-supporting lens shade which can fit almost any camera available thanks to a simple COKIN Adaptor Ring. The bellows provides excellent control over the ambient light conditions, and cuts the glare o...

E6 Slide Processing
If you are testing gear, using E6-process slide film is not only the cheapest way to do it, but also probably the best. You will instantly see whether the cameras are under or over exposing, you will not lose any special effects or filter effects you apply because there is no automatic printing mach...

Confessions of a Vain and Shallow Gearhead
We've just had a short thread on Pentax Macro Lenses, and how much we love them - often as general purpose lenses as well as the wonderful close up work they allow. I am the world's worst when it comes to image - not the image in the viewfinder or on the print - the photographer's. The minute ...

Flood Lamps
This topic doesn't fit into the established catagories, so I thought I'd try it here if OK by you folk. Hi! I'm having a lot of fun with Macro, tube, and bellows photography, and am not very good at exposure factors when using flash. I'm using Spotmatics (all three models) and find the TTL me...

Flood Lamps
The 3500K etc., refers to degrees kelvin, the absolute temperature scale. This is colour temperature, and the lower the figure the more red the light will be. It does also relate to wavelength of the light, but this is not directly relevant to the practicalities. To get correct colour rendition w...
