Translation of "Rotfilter" in English

Depending on the red Standard to be achieved, an additional red filter is then used.

Floodlights were installed and red filters attached to them at the foot of the dam wall of the Silvretta reservoir.

Also, a red filter can be fitted instead of the close-up lens.

The red filters were particularly pleasant, as red hot or black hot selectable.

The Red filter provides great colour correction in blue or tropical water.

A and D were measured behind a red filter, B behind green filter and C behind blue filter.

Only the filter lever is operated mechanically, which pivots the internal red filter in front of the camera lens.

The density loss of the cyan dye was measured with an X-Rite® densitometer equipped with a red filter.

How many red filters do I need?

When diving the adapter can also be perfectly used in combination with a magenta or red filter.

In addition, there is a red filter.

Analysis of precovery observations in the visible spectrum between 2002 and 2007 show that it may be amongst the reddest objects in the Solar System, being more than 1.5 magnitudes fainter in the G (green) filtered versus the R (red) filtered images, which may offer some clues about its composition and origin (also see color indices).

The results in terms of the sensitometric data measured behind a red filter (cyan maximum colour density and sensitivity) are summarized in the following Table.

After colour development, the photographic material on which the step wedge has been copied is measured in a densitometer behind a blue, green or red filter.

Only those nickel complexes which do not discolor the image receptor layer beyond densities of 0.07 measured behind blue, green or red filters when present in proportions of 50 mmol/m2 are suitable for use in image receptor layers or the dye diffusion transfer process.

Testing the filter exposures behind blue, green and red filters shows that the reproduction of green areas are markedly improved when using the dyes according to the invention without any diminution of the blue areas.

Therefore a red filter is conventionally arranged before flash and camera and a red-sensitive film is used.

Then the red spectral component firstly reaches a red filter 11 which improves the color separation, and afterwards reaches one half of a CCD solid body chip of a highly sensitive black and white CCD solid body camera.

Samples of these materials were exposed with a flash lamp (2×10-3 sec) through a red filter and a density gradation wedge. The exposed samples were processed in a roll developing machine for 30 seconds at 35° C. with a developer of the composition given below, treated in a commercial fixing bath, washed for 30 seconds, and dried.

The color densities which were measured under blue-(B), green-(G) or red filters (R), were measured after one hour of contact time and are summarised in Table 3.

The properties in percent (absorption maximum and half band width in nm, density increase on metallization (measured behind a green filter)), the subsidiary densities measured behind blue and red filters and the relative density loss in percent measured at high intensity illumination, and the dye transfers obtainable with the individual dyes after metallization with nickel are summarized in the following Table.

This colour picture was created from many monochrome exposures taken through blue, yellow/green and red filters, supplemented by exposures through a filter that isolates light from glowing hydrogen gas.

Red filter: Especially at night it is important to keep an optimal dark adaptation on both eyes.

As illustrated in FIG. 1, in the case of customary density measurements, an individual red filter is inserted upstream of a photoelement sensitive to white light and in each case filters out from the remission curves of cyan only a wavelength section around approximately 600 nm for the photoelement.

The density of cyan is therefore measured with the aid of a red filter at a wavelength of approximately 600 nm.
