One embodiment of the disclosure includes a key light source aimed at a subject, and an image capture position that includes an image capture device aimed at the subject. The subject is placed on an elevated platform. The background behind the elevated platform is a reflective material. The studio arrangement achieves a desired effect of a white background where a rear edge of the elevated platform is imperceptible to the image capture device positioned at the image capture position. ## Claims ### Claim 1 A studio arrangement, comprising: a background comprising a reflective fabric, the reflective fabric configured to reflect light shined upon the reflective fabric; an elevated platform positioned adjacent to the background, the elevated platform having a top surface that is transparent and a rear panel that is substantially white, wherein the reflective fabric is positioned on the background adjacent to the elevated platform to form a vertical gap between the elevated platform and the reflective fabric; an image capture position located a first distance away from the background in a longitudinal axis, the image capture position comprising at least one image capture device aimed at the elevated platform and the background, the at least one image capture device equipped with a ring flash positioned around at least one lens of the at least one image capture device; a key light aimed at the elevated platform and the background, wherein the key light is positioned outside of the longitudinal axis; and a rear light source positioned between the rear panel of the elevated platform and the background. ### Claim 2 (depends on 1) The studio arrangement of claim 1, wherein the elevated platform is approximately four feet deep, four feet wide and eleven inches in height and the gap between the elevated platform and the reflective fabric is approximately three inches. ### Claim 3 (depends on 1) The studio arrangement of claim 1, wherein the rear light source is affixed to the rear panel of the elevated platform. ### Claim 4 (depends on 1) The studio arrangement of claim 1, wherein the rear panel further comprises a white panel positioned between the rear light source and a transparent panel. ### Claim 5 A studio arrangement, comprising: a background comprising a reflective material; an elevated platform positioned adjacent to the background, wherein the reflective material is positioned to form a gap between the elevated platform and the reflective material; an image capture position located in a longitudinal axis intersecting the background and the elevated platform, the image capture position comprising an image capture device equipped with a ring flash; a key light aimed at the elevated platform and the background; and a rear light source positioned on an opposing side of the elevated platform relative to the image capture position. ### Claim 6 (depends on 5) The studio arrangement of claim 5, wherein the gap between the elevated platform and the reflective material is approximately three inches. ### Claim 7 (depends on 5) The studio arrangement of claim 5, wherein a top surface of the elevated platform comprises a transparent surface. ### Claim 8 (depends on 5) The studio arrangement of claim 5, wherein the opposing side of the elevated platform comprises a white surface positioned between a transparent panel and the rear light source. ### Claim 9 (depends on 7) The studio arrangement of claim 7, wherein the top surface of the elevated platform further comprises a Poly(methyl methacrylate) surface. ### Claim 10 (depends on 5) The studio arrangement of claim 5, wherein the elevated platform is approximately four feet deep, four feet wide and eleven inches in height. ### Claim 11 (depends on 5) The studio arrangement of claim 5, wherein the key light is positioned outside of the longitudinal axis. ### Claim 12 (depends on 5) The studio arrangement of claim 5, wherein the image capture device is configured with an aperture setting of f/11. ### Claim 13 (depends on 5) The studio arrangement of claim 5, wherein the image capture device is configured with a shutter speed of 160th of a second. ### Claim 14 (depends on 5) The studio arrangement of claim 5, wherein the image capture device is configured with a sensitivity of ISO 500. ### Claim 15 (depends on 5) The studio arrangement of claim 5, wherein the key light is configured with an intensity such that a light meter calculates an aperture setting of f/13, wherein inputs to the light meter are an ISO sensitivity of 500 and a shutter speed of 160th of a second. ### Claim 16 (depends on 5) The studio arrangement of claim 5, wherein the rear light source is configured with an intensity and direction such that a light meter calculates an aperture setting of f/13, wherein inputs to the light meter are an ISO sensitivity of 500 and a shutter speed of 160th of a second. ### Claim 17 A method, comprising: adjusting a ring flash associated with an image capture device based upon a particular sensitivity setting and a particular exposure setting of the image capture device, wherein the image capture device is aimed at a background including a reflective material and an elevated platform positioned between the image capture device and the background; adjusting a key light based upon the particular sensitivity and the particular exposure setting, the key light aimed at the elevated platform and the background; adjusting a rear light source positioned on a rear surface of the elevated platform based upon the particular sensitivity and the particular exposure setting; activating the ring flash, the key light and the rear light source; and initiating image capture in the image capture device, wherein a top surface of the elevated platform reflects light emanating from the background such the elevated platform appears a substantially similar color as the background. ### Claim 18 (depends on 17) The method of claim 17, wherein the ring flash, key light and rear light source are configured with a light meter, wherein inputs to the light meter comprise the particular sensitivity and the particular exposure setting. ### Claim 19 (depends on 17) The method of claim 17, wherein the ring flash is adjusted with the key light and the rear light source deactivated, the key light is adjusted with the rear light source and the ring flash deactivated, and the rear light source is adjusted with the key light and the ring flash deactivated. ### Claim 20 (depends on 17) The method of claim 17, wherein the ring flash and key light are adjusted such that a grey card positioned on the elevated platform yields, in an RGB color space, a red color reading, a green color reading and a blue color reading in a range of approximately 183-187.
