Hi,
here is my stream of consciousness ramble…
lighting, lighting, lighting…try to understand it…
and…
years ago, my camera savvy brother helped me to buy a point and shoot camera…he stood there and looked thru the viewfinder and fiddled with all the cameras available…and then said…”this one”…i later learned that it’s macro setting was a “wide angle”, so that i could get farther away from the object, and not hover up close casting shadows…
when i later tried to replace this camera, i found it very difficult to find a point and shoot with “wide angle macro…
i ended up buying a nikon camera body and a 1:1 prime macro lens…105mm macro and then later got other lenses…60mm macro…i like the 60mm better…gotta stand too far away with the 105mm
my brother told me a few things
fill up the frame with the piece…more data in the image…more ability to adjust…
understand histograms…a kind of graph of what data the image is comprised of…helpful when trying to figure out “how/ why” to adjust camera settings…lighting…etc…ie if you are “blowing out” the shot…histogram weighted to one side and not balanced…
the object is a mirror…it is reflecting what it sees…understand this and adjust the surroundings to control the reflections
Photigy videos taught me that you figure out what you want the object to represent and adjust lighting setup accordingly…ie: do you want to emphasize a sharp edge?…a soft rounded edge?…gem sparkle?… you do this by controling reflections…creating “gradients” of reflection…for example he would angle a light, to hit the diffusion panel, such that the panel has a gradient of light/ color bright to dark…and then make the object reflect that…
he would take a mini mag light and wave it around behind the diffusion panels/ boxes…and see where the light reflection hit the piece…and move his lights to where the mag light was…to help properly position his lights…
you are not lighting the object, you are lighting what the object is “seeing”/ reflecting…ie the diffusion panel, the bounce card…
light boxes…ie surrounding the object with white diffusion can sometimes “soften” the object more than you might like…not allowing for sharpness where you want it by using “gradients” of light, light to dark…
camera settings, lighting setup (is key), and reflections
overcast days…the sun is the light source…the clouds are the diffusion “material”
sunny days, no clouds…the sun is the light source…it is a hard light…no diffusion
usually don’t want “hard” light…want diffused light…my brother and i walked around walmart and he held up clear plastic totes and bowls…looking at the store lights…he showed me the results…said i dont wanna see a hard light shape thru the plastic…when deciding on diffusion materials…and when positioning the lights behind
if shooting with a macro lens, if possible, get a camera that you can cable to a laptop or pc…it is much easier to “see” on a bigger screen…my software allows me to take the shot from the laptop, or via a remote…and make changes to the camera settings and see the differences.
in addition to a remote, a tripod will help to reduce camera shake, which when shooting macro, can negatively affect the shot.
realistic expectations…shooting 1:1 prime macro has a very shallow depth of field…basically one distance point will be most in focus with front and back points blurred…professionally jewelry photos are corrected in “post production” software (a whole nother skill) using “photo stacking…where they take successive photos as they move the camera (usually on a professional stand/ track) with each shot focusing on a different point, from front to back…then they “magically” combine all the photos to get an image where the whole object is in focus…
jewelry photography is probably one of the most difficult of product categories to shoot…
and, highly reflective jewelry can be an even more challenging category…
just my ramble…
