That's not a feature of tripods, generally, but of heads. Geared heads, in particular, such as the Arca C1 Cube and the Manfrotto 4xx series. You would need to separately level your tripod or camera stand in order to make use of the calibrated markings on the head. (You can also get tilt scales on lower-end video-oriented pan/tilt heads, but you usually have ...


You may find useful this wikipedia page You can calculate the exposure value with the given formula: EV = log2(N^2 / t) setting: N = the f-number (aperture) you will use t = the exposure time you will use they both depends on your camera: search a middle aperture for your lens and a time you will likely use (a rule of thumb is that the slower time ...


It's not trivial to calculate from scratch the amount of light required (as you have no idea how much is absorbed, reflected etc. and it will vary according to how the lights are positioned). What you can do, is find out what shutter speed your camera meter is suggesting currently and work it out from there. You'll want to aim for 1/2f where f is the focal ...


Another thing to be aware of here is the post processing our brains do; brightness values are also adjusted by the brain. We don't tend to notice this, but without this effect we would have difficulties recognising object due to changes in the lighting conditions. So, it's actually quite a big effect. Even though an object in a shadow looks darker, it ...


The lightbulb looks overexposed, the dirt on the lightbulb which is so clearly visible in the first image is no longer visible in the final image. The whole point of HDR is to make all the details in both the extremely dark and light parts to become better visible.


I have done very similar product shots before. You can start with 4 lights. 2 in front with big softboxes to light the subject and 2 with big diffusers to light the background. Adjust the distance and power of each of your light to taste. There is no one right way to do it.


It's possible there was some focus stacking involved to get this DOF in the purple flower.


It's also very possible that the outside was darkened in post. The light might be from a twin-light flash where you can aim the lights more precisely.


Do you know how the image was made? It looks to me a lot like some of the flower images created by Katinka Matson. They're gorgeous, but they're not photographs -- the flowers are arranged on a flatbed scanner and scanned. The way the light falls off quickly and uniformly around the flower looks a lot like what you see in Matson's work.


To hazzard a guess, I would say that the lighting was done with a twin-tube affair, with the tubes arranged above and below the lens. The upper tube was the main (more powerful) light; the lower tube was fill at about half the upper tube's power (down 1 stop, or a 1:2 ratio with the "A" tube at the top). To get the fall-off you see from front to back, the ...
