Price Pledge ensures we won't be beaten on price! We actively monitor the prices offered by our competitors daily and adjust our own pricing accordingly. We pledge to match the price on most products offered by UK based dealers that are selling officially imported or manufactured UK stock, with full manufacturer warranty and is authorised to do so by the relevant manufacturer.
Prior to the point of sale CVP will endeavour to match the price on most products subject (but not limited) to the following criteria:
For further details please call us on 02083807400.
Details of where you have found the cheaper item.
The prices shown are an estimate based on the purchase of a single item with nothing else in your basket. The prices and options do not include shipping regulations and duties which will be checked in the checkout process.
At CVP we always strive to get your order to you as quickly as possible, but in the interest of clarity please note that next day is defined as the next working day (ie: excluding weekends, UK bank holidays and public holidays).
Orders placed and security cleared before 14:00GMT where all items are in stock will normally be dispatched on the same business day for ultimate delivery according to the shipping method selected.
Where an item is not physically in stock, the actual delivery time will be extended by the lead time for the product in question. Shipping to the Channel Islands, Northern Ireland, Republic of Ireland and some remote UK postcodes are not next day but 2 working days.
All transactions are subject to CVP security checks which are for our mutual protection against identity theft and fraud. In the event that additional checks are required you will be informed and dispatch time will be extended by the time taken to resolve any queries raised. We apologise for any inconvenience this may cause.
*Due to unforseen circumstances, on some occasions same day dispatch may not be possible. In this event we will always do our utmost to keep you fully informed of any delay imposed.
After a clear protection filter, a polariser is probably the first filter which any camera user should purchase. The principal use of the polariser is to eliminate surface reflections, glare and hot spots from any light source entering the camera. This reflected light often shows up as a whitish glare which reduces the colour in the image. The polariser is used for colour and contrast enhancement and removes reflections from substances such as water and glass. It can darken a blue sky and increases colour saturation.
When two polarisers are placed together it is possible to achieve near black out, dependent on the angle in which they are aligned. This enables intense effects to be created. One of the polarisers is rotated until the required effect is achieved.
POLARISING FILTERS EXPLAINED:
Natural daylight is partially polarised. When light from the sun hits molecules in the atmosphere, the blue end of the spectrum (the short wavelengths) is significantly scattered. This scattered light is partially polarized. The red end of the spectrum is largely unscattered and consequently less polarized. The resulting light reaches the surface of the earth from all directions and makes the sky appear bright and blue. Without an atmosphere the sky would appear black.
Use of Formatt polarising filters can remove the scattered (and partially polarised) component of the light and only allow light in one plane to pass. The effect of this is to darken clear skies. Where there is moisture present, mist, haze, smoke etc, the scattered light appears white owing to the large size of the molecules. These larger molecules have a depolarising effect. Consequently using a Formatt polarizer will significantly increase the contrast between clouds and sky.
From Malus’s Law the maximum level of light which can pass through a polariser is 50%. Formatt filters are HN38 polarizers, meaning that a maximum of 38% can pass. This equates to 1 1/3 stops and suitable adjustments should be made. Formatt uses a very high specification iodine tinted polymer for its polarisers, ensuring a neutral grey with a flat transmission curve, minimising the risk of any colour distortion.
Extinction values on crossed Formatt Polarisers are better than 98%.
