Kim and Marlow argued that this inversion of the background provides useful information for the appearance of transparency. Because this object was made of solid glass, it inverted the general coloring of the background so that the blues of the sky were primarily visible in the bottom portion of the object, whereas the greens of the ground were primarily visible in the upper parts. Another experiment by Kim and Marlow ( 2016) used an object with sufficient complexity that the background scene was distorted beyond recognition. One important limitation of these studies is that the front and back surfaces of the depicted objects had very little curvature, so that refractive distortions were much smaller than those that can arise from glass objects with more complicated 3D structures. This work was later extended by Schlüter and Faul ( 2014, 2016) who showed that observers can perform this task based on the pattern of specular highlights on a surface without any visible texture in the background. In one of the few experiments on this topic Fleming, Jäkel, and Maloney ( 2011) showed that subjects can match two glass surfaces against textured backgrounds by adjusting the index of refraction on one of them. ![]() 14.Although there have been a number of studies on how subsurface scattering of transmitted light influences the perception of translucency (Fleming & Bülthoff, 2005 Marlow, Kim, & Anderson, 2017 Motoyoshi, 2010 Xiao et al., 2014), much less is known about observers' perceptions of clear transparent materials. Slowly change the angle of the second phone to find the perfect reflection. Then, hold it just below the lens of the camera phone you’re using to take the picture. To do this, you need the second phone to be off, or on stand by because you need the black screen. Just because you can get so low, it doesn’t mean that you have to, so instead, experiment with different angles to find the perfect reflection.Ī fun tip is to use one phone to capture the photo, and a second phone to create the reflection. This has to do – amongst other things – with the fact that using a phone you can turn it upside down and have the camera at the lowest possible angle. Some subgenres have become particularly popular, for example photographing reflections in puddles – or #puddlegrams as they are known in social media jargon – see above for one example. Taking reflection photos is something you can easily do with your phone because it doesn’t require any specific gear – it’s more about the subject, the lighting and the camera angle. ![]() You can do this with the flip or rotate function in any app or editing software. To trick the mind and make your reflection photographs more interesting, try flipping them upside down. Sometimes by changing one small thing, you completely change its perception. That’s it, have fun making surreal reflections in puddles. Then, create a layer mask and paint black the puddle to give visibility to the puddle with the reflection from the bottom layer. So, move the layer to have them match perfectly – zoom in if you have to. They should be lined up because you used a tripod, but the shoes might need some adjustment. Later in Photoshop, open both photos in the same document as separate layers – make sure the second photo is on top. Once you shoot the first image, carefully have the person step out of their shoes (or reposition them in the same point) and do a second photo. Also, use manual focus and set the focal point to the shoes. To do that, it’s best if you have your camera in manual mode so that you can maintain the same camera settings. Ideally, both photographs need to have the same exposure and focal point. Then, position the person and take the first photograph. First, place your camera on a tripod because you need both images to be framed exactly the same. To do this, you need to take two images and blend them in Photoshop. ![]() Have you seen images where you see the reflection of a person in a puddle, but on top of the puddle, there are only the shoes and not the person – like the example image I shared above.
