Hi all: having a second career as an underwater photographer and documentary film producer for the last 30 years , with 2 illustrated guide books to my credit, I have been behind the lens since Bd (before digital). I have looked through the many useful comments and condensed below my own approach.
The commonest errors made by amateur camera operators are:
Poor focus
Bad lighting, shadows, hot spots,over/under exposure
Moving camera/camera shake-blurry image
Bad composition/screen clutter/too far/close to subject/weird orientation or POV
Lack of scale
Equipment; even with 100K in advanced pro camera gear I use for work the good news on the first 3 items above is these can largely be overcome by the features in newer phones and cameras which have raised the general level of quality of amateur images tremendously. I use my iPhone 13 for most images. Its quick, easy and has excellent close focus and light capabilities, fast image transfer to desk top.I carry it everywhere I go so ease of use and transport are great. I rarely post produce my images and rely on a good shots to start with, not hours in processing.
Lighting_ very inexpensive options available for diffuse lighting notably the LED ring light which you can get on Amazon or equivalent for 20 bucks. Reflectors can be made from pieces of white cardboard or thin plastic , flags ( cut out hotspots) can be made from dowel and smaller pieces of cardboard
Steady rests- just like on your lathe, these essential tripods, monopods and other devices decrease camera movement and allow hands free operation. The Gorilla pod and its friends are great and can be mounted on travelling items like compounds for video shots.
Lack of scale- use a ruler or credit card/known size object as close to the subject as possible
Composition- reams written on this, for documentary purposes of artifacts a few essentials -clean background, entire object in field of focus, subject at least one third to one half of entire image or crop in, closer is better but avoid shadow by using fill lighting, use parallel or upward camera angles where possible, rule of thirds for pretty pictures, birds eye view can cause disorientation unless there is context in the image if complex artifacts are being imaged
Sequence- I recently rebuilt a Bauer dive compressor and photo documented the process step by step so I had a guide for re assembly. Its helpful to add hand written notes and photo them as you go along as sign posts to remind you of what you did which will log in chronological order when you download your images. Of course you can also use the metadata on the images but the use of a pad and pencil is easiest for me. I have also used these notes during project builds to remind me of where a difficulty was encountered and overcome if the images don’t realty tell the story. I will often doodle draw a sequence of actions when executing a particular project, kind of story board the build if you like, before starting. This walks you through the whole process before you start cutting metal and gives you clear bench marks for the build, rather than staring off into space in your shop thinking “whats next?”
Last rule-clean your lens regularly especially in the shop with dirty hands and soil around.
