focusing ALL product image?

Hi,

I have always had a very difficult time getting my entire product - jewelry - in focus. Drives me nuts!! Attached is a photo I just took. Almost all of it is in focus except the bottom front. I am shooting in Aperture Priority Mode. 18-55 kit lens.

A- F16
S -camera chooses
ISO -2000

Shot inside around 6:45pm with loads of artificial light.

(I make and sell jewelry online. Stretch bracelets are the hardest for me to keep ALL in focus.)

I use a cell phone app that shows the DoF based on the body, focal length of the lens, aperture , and distance from camera to subject. Since I don't know all the exact specifics, I chose a Nikon DX body, 55mm lens, and f/16 as the specs to use as the example below being 12" away from the subject (this was the app called Simple DoF which I believe is a paid app).

Keep in mind there is a greater area of sharpness behind the focus point than there is in front of it which is why it's best to focus about 1/3 of the way into your subject/scene. But based on the specs I used, the area of focus that will be reasonably sharp is less than 3/4". So if you are shooting subjects that have have some depth to them, focus stacking might be your best option like Sparky mentioned.

I am assuming you are using a tripod or some other form of support and not shooting freehand. If you use a higher f stop number in your aperture, the image should all be sharper, as a whole, if I am not mistaken. If your lens distance was on the border of it's focus from the closest part of the bracelet, it won't get sharp, no matter what you do, so you would have to back away a little more. On the "bottom" of the lens (when you have it mounted) the minimum focus distance is there, for your widest and longest on your zoom. Also, if you spot focus and meter on the same spot, try a half press the shutter on a red or darker bead in the front, at the f stop you are using, and see how that looks. If the front of the bracelet is in sharp focus, the rear won't matter, in my opinion. We tend to look at what is closest to us, so that would more or less be the main subject in the picture.

Not 100% sure - always happens when I post pics... I get the bb code for my image which is formatted like below (without all the spaces):
"[ URL = "https://www.kevinmcginn.com.au/Portfolio/Weddings/i-cfWhKZJ/A" ] [ IMG ] https://photos.smugmug.com/Portfolio/Weddings/i-cfWhKZJ/0/7bda77b0/L/1-KM1_7934-L.jpg [ /IMG ] [ /URL ]"

And the exif data just appears. Not sure if it is something to do with my website, or something to do with Nikonites... or even both... :)

How did you get the exif info on thee photo like that? That's really helpful!

You posted your image as an attachment instead of posting the image to the post. That is probably why the exif did not show up. Look at your post which shows attachment on the border vs Kevy's image he posted. No attachment in the border. Sometimes the site likes to play with what you post. May have to try again to get it posted on your post.
