Free Web Gym Templates



Mi sono permesso di esercitarmi con l'immagine precedente cercando di ottenere un effetto da vecchia foto. Ovviamente tutta la postproduzione รจ condotta in Photoshop.

Can You Take Ambien After Drinking



In this scene the main interest was devoted to the feeling you wanted to convey: a situation of calm and serenity, silence and peace. It is a scene study, not created for commercial purposes, and has therefore been taken due to the adjustments necessary to improve the final effect. For the calculation of the final image you used the version of Indigo for Linux 64bit operating system: in this way it was possible to optimize the use of 4GB of RAM, not fully recognized by Windows. The process of information management on Linux is also by far more effective than the Windows environment: the times rendering have been reduced by about 20%.
The post included the addition of chromatic aberration, the selective color correction, sharpening a generic effect of a diffuse glow at the window in the background. Again we used a short throw, which makes objects in the background somehow ethereal, contributing to the determination of the final effect you want.

Webbed Toes What Do They Mean?



This simple scene did not want to go into the exploration of some techniques in particular: he wanted to be a mere exercise in composition, both in terms of color from the point of optically with the balance of the volumes. The capital, a model for free download from archive3D , is characterized by a simple light travertine that sticks to the blue background, and set on the right, centered in height. The composition also includes positioning the digital signature, which in this case slightly balances the weight of the subject. The virtual camera used to photograph the subject has a f2.8 lens, which determines the depth of field: in this way we could get a slight blurring of the edges further away from the camera, which makes taking a total of more dramatic . A minimum post-production adds a slight chromatic aberration.

Other experiments on materials SSS: in this case I tried to put synoptically evidence in the physical properties that characterize this family of materials. The volume rendering of the object is a block that has a curved section areas thinner and thicker areas, the regular volumes in the foreground vary only in thickness, the texture be applied to the basic plan gives an idea of \u200b\u200bthe actual objects DIMENSIONS. The texts were three-dimensional model in SketchUp using the appropriate tool testo3D .

Older Short Bed Truck Campers



This post concerns an old scene I used for a short tutorial a while ago. The environment is extremely simple: the only material a bit 'special is the floor, terrazzo. Being a scene for the less experienced, the settings were not esssere too complex. This time the rendering was completed with Indigo 2.2 (commercial version ). The experiment was part of the largest post-production phase, in which an attempt was made to put in stark contrast to the light tones and dark tones: the effect you get is a vernacular that sort of environment, all things considered, I did not mind.

Eagle Scooter Wheels 125



With this picture I get back to some experiments on materials Sub-Surface Scattering, which absorb light refracting within them. We sense that this feature tends to converge towards dissimilar results depending on the model which the material is applied: the variability of effects that can be achieved is truly amazing, and that is why it is useful to conduct various tests to fully understand the behavior. The basic model has been downloaded for free from 3D Archive, an excellent resource for many good models that can be imported into SketchUp. The SSS is made from a material specular shader (shader that is used for any type of glass) with a light absorbing color orange tones, which gives just the base color of the statuette. The scattering parameter active while the internal refraction which reduce the transparency of the material as and when light passes through it. In this way, as you can see, the more subtle areas such as borders, are almost transparent, while the internal parts are more opaque.
The final point in this picture, the method for calculating the SDS: the current commercial version of Indigo, the 2.2, has made several modifications to the algorithm for calculating the material scattering, simplifying and speeding up the rendering process for materials with uniform value SSS. In this case it was desired to test the actual efficiency improvements and found a significant improvement: the rendering time of 4 hours, and good definition of the material, although not yet very clear.

Chicken Pox Can They Come Out In The Mount



Some of my experiments, this time regarding the use of 3dsMax, of course, in collaboration with Maxigo, Indigo Renderer plugin for the model of Autodesk. This image, which is extremely simple, portrays an organic entity, a birch tree, resting on a surreal white top that seemed effective to remove chromatic contours verdidel foliage. The tree is a business model that can be found in the collection of 58 of Evermotion Archmodels . Experiments were performed on leaf material (a material phong partially transparent) and some simple steps in photoshop.
