To create a Free light: On the Create panel, click Lights. Choose Photometric from the drop-down list. (This is the default.) On the Object Type rollout, click Free Light. Click the viewport location where you want the light to be. The light is now part of the scene. Initially...
In this paper, we introduce specular-free residual minimization that avoids the negative effects of specular reflection components by projecting the residual onto the complementary space of the light color. The minimization process simultaneously searches for the optimal light color and other parameters. ...

signal-to-noise ratios (S/N) but are probably underestimates of the true errors, since we do not account for systematic uncertainties related to, for example, photometric calibration, background subtraction and/or parametric assumptions for the intrinsic light profiles of JADES-GS-z14-0 and ...
Achieving globally uniform diffuse reflection illumination with static ring light makes it difficult to distinguish between low reflectivity caused by surface stains and shadow areas; whereas in the pseudo-color image, the local concave shape of the defect is very clear, significantly improving the ...

A photometric apparatus is capable of obtaining a precise photometric value without any saturation of a photometric output value even when measuring a light intensity of a flicker light source. The photometric apparatus has a photometric portion for measuring the field by use of a charge type photom...
A photometric device for determining the exposure interval for a scene to be photographed includes a photometric array having a plurality of individual photocells that are each adapted to receive light reflected from a selected portion of the scene. Each photocell provides a signal output that is ...
Furthermore, the cell receiving the light through the same lens which passes it subsequently unto the sensitive emulsion, will also register the effect of the very same quality and quantity of light as reaches the emulsion and will be free from variations resulting from the different transmission ...
If in a solution of simple salts the concentration of free meta! ionswas inconsiderable (as a consequence ofhydrolysis) it should become still less on introducing strong complexing agents, such as tartaric acid, hydrogen peroxide, oxalic acid and others; however, these compounds, which frequently ...
