Contrary to the item description, the width of the supplied background material not 285 cm, but at least about 300 cm. It is thus, for example for use with the 307 cm wide Walimex Telescopic Background System or other background system, which contains the 307 cm long Walimex Telescopic Background rod, ideally suited. For a wrinkle-free attachment to the walimex 3-Fold Background System of material, however, is too broad. Usually, it makes sense, the background fabric with two suitable clamps (z. B. to secure Walimex Studio Clip on the crossbar of the background system to prevent slipping and to stretch.
The background material contains naturally pronounced wrinkles, which originate in particular from the rectangular folding in the transport packaging. The folds can be largely eliminated, however, by the fabric is hung up on a background system and processed with a steam iron. The remaining smaller wrinkles are usually acceptable because usually the background looks blurred when shooting portraits. In addition, the background fabric should in principle not be sharp in order to avoid moiré effects.
The relatively light background fabric is of course not light-tight and therefore not completely opaque. However, that fact is often problematic, since usually worked before the background fabric with flashing lights, so that the contribution of the translucent through the cloth background light is negligible. If required, however, a correspondingly suitable background system could be used with a second, halfway neutral background fabric to make the background opaque.
The color of the background material is not neutral gray, but blue-gray. With an even soft lighting and blurred image of the cloth has a noticeable color saturation of approximately 10%. The color on the color wheel is approximately between 220 ° and 230 °, making it blue. The luminance is approximately between 40% and 50%, so that the substance is only slightly darker than typical gray maps, which are used for light.
The blue color makes the background fabric especially for portraits very interesting. Due to the simultaneous contrast Patterncolors appear against this background some reddish or warmer, which may be beneficial for skin tones in particular. This anwärmende effect occurs already with proper white balance (in which the background is displayed correctly in blue) on. The blue color of the background also lets you to adjust the color temperature in the white balance inconspicuously to warmer shades towards. The background color changes from blue-gray while a more neutral gray, while all other colors are warmer motive. When the white balance so far as adjusted, that the really blue gray background appears completely neutral gray, is the shift of about 20 to 25 mired. (Ie, the effect is approximately between a CT Straw- and a CT Orange correction filters.) So you can for example in a typical flashlight with an actual color temperature of about 6,000 K color temperature for the white balance up to about 7,000 K increase of without background gets an orange hue.
