Here are a few photos of a library install we’ve been working on for the last couple weeks. It’s all prefinished mahogany.
Any suggestions on why I am getting these white circles showing up in my photos?
Dirty lens?

Doug: That needs to be in FHB. nice work. My camera does that circle thing also. I cleaned everything...and found out if I dont use the flash...they dont show up.
Now that is impressive!!! I agree with Stan you need and article of your own.
Those spots are from a growing organism on the lens coating. More than likely on the inside side of the lens. The seal in the lens has broken down. If the camera is still under warrenty change the camera out. 200 proof denatured alcohol will kill it and you risk damaging the coating further

Thanks,
I get this almost everytime I use the flash.
I will try and return this camera as soon as possible. It is fairly new.
I need to take a bunch more pictures of this house since we don't get to do this type of project everyday.
We've been trimming this monster since September, 2003.
Take some sample pics with you. Make them give you another camera. DO NOT accept a repair because the camera has become a petrie dish. Defer them to me if they give you any crap.
I have some very exotic expensive lenes that have done that. After a while crystals will start to form. The flash refracts thru the growth rings. that's why you can see them.
BTW what camera brand / model is it?Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming.... WOW!!! What a Ride!
Imerc: I am taking your excellent advice as well. Thanks for what has been puzzling me with my camera for months.
At some stage of the manufacture of the components or assembly some minute piece of contamination got on the lens or inside the camera and it goes downhill from there. The clean room wasn't so clean. When lens companies started to sub the manufacture out to gawd knows where these problems started to really surface.
Nikon lenses are made by Tameron. Tameron then subbed to the Chinese and Bangladesh. Gazillion dollar lenses become junk because of quality control or some small thing. Nikon, Canon, Kodak, Sony, Vivitar and Pentax use the same manufactuers. Olympus has their own facilities. The upshot or would that be downside is people get to handle the product during the building process and if somebody somewhere's came into work with say a head cold, lunch under their finger nails or doesn't like to bathe........ UCK....
On a better note it could be just poor quality optics or coatings. Clarity isn't as clear as clear can be. Grit left on the lens after polishing. The seal or seals leaked and natural contaminates entered into the lens assembly....
From what I could see the crystal growth has already started on Dougs lens....
Glad I could help..... Now how many others are gonna be going back to visit with their camera retailer as I saw other posted pics with the same problem... LOL!
One solution is to test the camera before you leave the store. Macro the print and pictures on paper currency for overall clarity. Take an oblique photo of a bright light to maximize the refraction thru the lens. Light steaks with prizmatic colors are a fact of life because of the curvature shape of the lens and it will take a hefty wallet to get around that. Concetric rings is contamination orgnic or inorganic. A soft focus spot or spots is generally poor quality.Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming....

Dude, what a gushing fountain of knowledge you are..now I gotta screw around with my new Sony..had it 4 mos or so..same deal sometimes. At least I got a warranty..Thanks man.

imerc... like duane said.. a font of info.. i've noticed similar but most of the time it was just dust
this is a Nikon Coolpix 995.. i think Pro-Deck has the same model..
my biggest problems with digital are stop -action.. blurring if the subject moves.. and backlight..
i understand the stop action is slowly improving with the new families of digital..
as to backlight.. i try to use fill-in flash.. but naturally , with back light the flash doesn't want to trip.. especially in Auto mode..
so i aim at a dark corner of the room .. trip the shutter and swing back to the backlit subject..
here's two samples.. one with no flash.. the other with the fill-in..Mike Smith Rhode Island : Design / Build / Repair / Restore

I don't recall spotting in Pro-dek's pics. Yours I do. I want an Olympus (IIRC) 60 series or a Nikon 660. The OM-60 is an OM4T in digital at 8.5MPX / 1.2GB card. I have an absolutely stagering boat load of Olympus 35mm and it's all compatible. The Nikon is a digital F5 and a little up from the OM. Why waste what I have. Both cameras are in the 12/14K$ range... OUCH!!! But these cameras can be upgraded as time goes on not likely to get run over technology. The OM20 is a nice piece of equipment too. Maybe it's the OM100. Damn CRS.
So add Olympus to Bosch and Milwaukee. Beware.
my biggest problems with digital are stop -action..
Welcome to the world of digital format and optics. I think true optical optics will help aleviate some of this. Shooting at a lower MPX helps too.
blurring if the subject moves..
Takes time to load... Better camera - faster loading.
as to backlight.. i try to use fill-in flash.. but naturally , with back light the flash doesn't want to trip.. especially in Auto mode..
Practice.... Read the light at your feet and not from a dark corner. Some of the OM's can average the light from several points for you and shoot at that ambience. Become one with your manual mode. Auto is for 'cruits. Look for cameras with TTL metering and spot reading cababilities.
so i aim at a dark corner of the room .. trip the shutter and swing back to the backlit subject..
Look up...
here's two samples.. one with no flash.. the other with the fill-in..
The first is a wash the second is art but I think it could use a fuzz more flash. But I gotta know who put in the washboard ceiling.....

imerc.. not washboard... that's skim-coat plaster with backlight so it shows up that way.. actually , the swirl pattern is pretty nice..
sand finish swirl pattern is pretty standard for skim-coat.. usually i spec smooth in the bathrooms .. sometimes smooth in the kitchens and swirl every place else..
each plasterer has his own signature with the swirl.. most are some combination of interlocking fans..
this house is 10 years old.. so i don't know who did the ceilings.. we replaced the window because the old one was absolutely the wrong one...
here's a pic of the window with the blueboard outlining the old window we took out.. it filled the space from wall to wall... and was rectangular..... either they chose too big a window.. or they made the dormer one rafter set too narrow
as to lenses.. i have some great lenses for my old Nikon FM that i've had since '72.... but since i went digital , it's stayed in it's case for the last 3-4 years

Sometimes spotting the odds go to a dirty exterior lens. Outside? Clean the lens.
Most always spotting even after cleaning the odds go to spots being on inside. Inside? Change the camera.
FWIW.. Use a piece of chamos to clean the lens. Just make sure it's not been cured using vegitable oil.Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming....

Thank you, sir.....for an explanation to a problem I've seen on several occasions over the years but couldn't quite put my finger on. As you stated, if exterior cleaning doesn't resolve the problem (and it didn't in these few instances) it's almost gotta be an "interior" problem. I never did really figure it out. The petrie dish explains it all and makes perfectly good sense. It even looks like one.
It's damn obvious you have both extensive knowledge and experience and what you've said about the current state of reduced quality control is a dandy forewarning of things I can bear in mind when purchasing a new dig-cam. Several friends here have Olympus dig-cams and I haven't yet seen a photo from them yet with this petrie-dish abberation, either. Sounds like the best bet is probably to follow suit now that I've been advised.
I'm familiar enough with the type of lens phenomenon that One Putt referred to, but that's not what I'm seeing in those library pics, either. Airborne dust maybe, but I'm gonna say not likely judging from the type of refraction revealing the lens aperature. That sort of thing IME is nearly always repeated in a linear fashion pointing to the light source or sometimes is just a single spot, but not the type of toatally random spotting seen in the library pics. That's gotta be either airborne dust (room doesn't look that dusty in general), or caused by dirt on the exterior of the lens or the now explained.......petrie dish.
Here's a good example of that lens aperature phenomenon in repeated fashion. (I did this one on purpose cause I knew I'd get it, but just wanted to see if I might like the effect in this particular photo.)
Knowledge is power, but only if applied in a timely fashion.
Thanks, glad some body caught what I was trying to say....
BTW how come you didn't leave a note when ya stopped by the house....Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming.... WOW!!! What a Ride!
schweeet!
Well.....cause I could hear ya sawin' logs in there and didn't want take any chance that I'd disturb ya. I was kinda scared that just the sound of the shutter might do that, but I risked it.
Maybe next time.

Really beutiful work. DanT
That is absolutly beautiful, there's no more satisfaction than working on one of these houses, I only get to once in a while and enjoy the hell out of it.
Very nice work,
Doug
Doug,
Nice looking work! I believe your photo problem of white circles is fairly simple. I assume that you took these using a flash. The circles are simply light reflecting back from dust in the air. Attached is a photo I took recently in a granular product storage warehouse. It was a very dusty environment so this is an extreme case. See if these circles are not similar to what you have.
P.S. I am having trouble attaching the photo. Will work on it and get back to you.

Thanks to everyone who has weighed in on this subject of the spots in my photos.
I have thoroughly cleaned the lenses and taken some photos in a dust free but dark room and only once have I seen any spots appear and that was a photo I took into my bathroom. Maybe just light reflecting off the mirror somehow.
I will try to take some more photos in the mahogany room and see if any spots show up this time. It could be dust in the air as this site is always dusty. I'm afraid if that's what is causing the spots then the PM will want us to move all our saws outside:-).
Here is a link to some more photos (complete with white spots) if anyone's interested.

On the lighter side - maybe they be crop circles.....First we get good- then we get fast !
Doug
That's one serious house your working on, those added pictures are fantastic!
Where you at, what state?
Doug
We're in Central NC near Greensboro.
I have taken a few more photos today to see if I can determine what is causing my spots. I'm leaning toward dirty lens or dust in the air.
Doug
I get the same thing and that was with the camera right out of the box.
Doug
way cool doug.. is that guilford , CT ?Mike Smith Rhode Island : Design / Build / Repair / Restore
Let's see if the attachment made it.
Beautiful!!
I suppose IMERC could be right, but I seriously doubt that all these folks suddenly have cr@p growing in the lenses.
It's more likely do to bright lights and shiny surfaces. Id imagine you've noticed that sometimes movies or videos wil have rows of spots like that, often octagonal or hexagonal.
That happens when sunlight falls on the surface of the lense, and it reflects inside the lense body. The shape is a product of the leaves in the lens aperture.
That's what this looks like, and could be produced by the flash reflecting off that shiny mahogany, or by a bright worklight too close to the frame.

So many people preach equity in golf. Nothing is so foreign to the truth. Does any human being receive what he conceives as equity in his life? He has got to take the bitter with the sweet, and as he forges through all the intricacies and inequalities which life presents, he proves his metal. In golf the cardinal rules are arbitrary and not founded on eternal justice. Equity has nothing to do with the game itself. If founded on eternal justice the game would be deadly dull to watch and play. --Charles Blair Macdonald
That's mighty fine work. Thanks for sharing.
