![]() ![]() Use the material to line the inside of a cardboard box or drape over a chair/table.Find some thick black material (velvet is the best material as it absorbs light but any dark and heavy-ish fabric will work).Whatever camera you use keep practicing and experimenting until it becomes familiar. No DSLR? – don’t worry you can use a little point and shoot camera or your camera phone and still get good results- but the images will be of a lower quality and you will have less control over what the camera does. White balance set to daylight if using natural daylight- use AWB if unsure or using mixed lighting (i.e.Shutter speed above 1/60 unless you have a tripod.ISO – 400 in cloudy conditions, 200 in bright sunlight.Inside I think they can make some skin look a bit sallow and who wants that?įor general use in other words I prefer white but there are certain situations where gold and silver can work.If you are using a DSLR camera these settings are a basic guideline for shooting in natural light/sunlight. I actually like the foil reflectors used more outside where it's hard to set up a V-flat and where you'd actually expect more of a sun kissed skin tone. V-flats, a window, some sheers doubled up, maybe a white reflector, that's near perfect portrait lighting for me unless I want to go dark and moody. I have studio lights and flashes and I use them sometimes but I really prefer a more natural looking light and I think the V-flats and a window or other source of light with diffusion gives me that. I've started using my own home done version of a V-flat a lot and white reflectors in the front et all because I think it's a bit nicer on the skin. I'd rather use more white, than gold or silver most of the time because it's more neutral even though it means using more of it. Metallic reflectors can cast reflective tones I actually don't want as well as ones I might. I like to use both because sometimes that is what I want a warmer skin tone but using a metallic reflector can be problematic sometimes when it comes to photographing people with very light or very dark skin. Who would have thought you could grow tomatoes inside a speaker?Ī silver or gold metallic reflector or umbrella will generally reflect more light than plain white but it can also cause unwanted warmth or uneven skin tones where you don't want them. This is not pertinent to photography but if you are trying to build a 'grow spot' inside of a wooden speaker cabinet then thermal reflectivity is apparently of significant interest. When you discuss thermal reflectivity then foil is far superior with white paint being quoted as only 50% reflective but foil being 85% or more. It is interesting to note that light wave lengths enter into this and the figures noted above are for visible light. So based on that, I would think you would see marginal at best improvement going to household foil but that mylar might make a difference. White paint 80 - 85% depending on gloss and brand And I got quite an education, using google to search for reflectivity of aluminum foil leads you to all sorts of websites with information on various forms of 'indoor gardening'.Īnyway, the numbers do vary considerably depending on source but these seem to be common: Ok, so you got me thinking and I did some research to satisfy my curiosity. With that into account how many stops more do you think the foil will put out, compared to the white interior? ![]() white and in the link to the experiment BrianR linked to it's noted that some light escapes through the material not my case since i'm using 10mm thick MDF boards But again I think the difference will not be dramatic.between flat & glossy, you're right not so dramatic I think in this case it will make a difference but probably not as much as you hope.Īnother thought: you used flat white, so you might get some increase by repainting with gloss. The only real way to test it on your particular box would be to take a light meter reading with the white and then line with foil and take another reading. Plug in different numbers and you get a different result. Most of the light is already heading forward so how much of the total is going to be reflected? 30%? and how much more will aluminum reflect than white, maybe 30%? So using those numbers you get a total increase of maybe 10%. However, in this situation will it be noticeable? Based on my experience with reflectors the aluminum will definitely reflect more light than the white. ![]()
