This produces a layout enhancement effect as shadows then play the role  of negative halos. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Glossy &#8216;n tasty<\/h3>\n\n\n\n<p>One may ask &#8220;how tasty&#8221; a substance is, which really means &#8220;how rich in tase&#8221;. But this is a limited characterization, reduced to a single all-encompassing dimension. <\/p>\n\n\n\n<p>One may then try to characterize taste in terms in (proximal) features: salty, sour, sweet, bitter, dull, etc. This is like looking at image features of gloss, like sharpness, contrast, coverage, color, etc. <\/p>\n\n\n\n<p>However, taste is arguable more complex than a collection\/combination of tongue features. For instance, oenologists use references to fruits or spices to characterize wine in tasting. What help them make that connection? A succession of tongue features? Passive or active?<\/p>\n\n\n\n<p>There&#8217;s a difference between a wine reminding of fruits and the actual taste of fruits of course. The same occurs with paintings of glossy objects, or even objects that remind other (more common) ones, like a flower having a satiny, velvety or metallic look.<\/p>\n\n\n\n<p>One possibility is that features occur in combination with other substance properties, like texture or shape, and we&#8217;re sensitive to these correlations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Vision regimes Vision during locomotion or object inspection or contremplation greatly differ.
