VERY NEW.
Been testing two days and getting this. (Of course I can smooth it but no detail then.)
Need some tips getting started. Using Canon 60D with 50mm prime lens.
Tried lots of pics, less pics, settings found online, (even tried phone camera) no luck getting rid of my noise.
I’m sure its something basic but can’t figure it out.
Thank you
Be worth uploading a sample photo so we can get an idea of what the surfaces look like.
Hi David,
is your object reflective ? Is your image overlap good enough ? Is there some snow or sand on it ?
You have to send some sample images and also zoom out a bit in RC to see the camera positions.
Fixed/discovered 90% of my problem(s) and commenting so other new users can avoid a few days of learning curve. Please add other hints since I’m still very green.
Most of the subject was molded plastic with small shiny surfaces I did not think were “reflective”. First tests should be something “organic”, a potted plant worked for me. This combined with sometimes using a flash during testing created unnecessary reflections/noise. Anything reflective, painted, plastic, metal, etc can give bad surfaces, at least during my preliminary testing.
ISO was well over 400 making my camera over process, used low light sometimes, unnoticed noise in pictures, not perfect clarity. Reduced ISO, Increased light, kept f stop in mid range around 8-10 for lens max clarity sweet spot. I underestimated the quality of photo’s required. Besides the basic camera settings I turned on some noise removal, very slight overexposure seems better than slight underexposure, at least for noise. Good photography technique is a must; camera ISO 400 or less, handheld speed never under 125, f stop at the lens best focus sweet spot (8-10 for a 50mm prime?), select lens for greatest depth of field, if using auto-focus use thru the lens and not LCD auto-focus, more accurate. [my test camera was a canon 60D, so your mileage may vary)
Although I took many photo’s around the object, I failed to go around again at different elevations on my first tests…
I now feel like I’m on the right track.
You’ve learned fast - as a non photographer took me weeks to understand all the ‘good photography techniques’ parameters that you rightly list. I use only ‘camera-native’ ISO100 - 400 is noticeably more noisy.
Mind you, pot plants and chain saws well lit outdoors are easy - try interiors of inhabited rooms full of clutter and occlusion, lots of featureless plaster surfaces, poor natural light, photographing outward to a perimeter rather than inward to the object … learing is slow, but steady, solutions appear.
