Tips For A Beginner In Taking Photos Of Coins

Many things will be discussed here, but 1st no flash!
To the best of my knowledge that is never used in coin photography.

Not sure how valuable your coins are, but if moderately valuable and you are selling as stated, you may reap benefits from a new setup. I started a few months ago reading through and purchasing the items in this thread;

For the meantime, you could provide the model of camera you are using and post some images. There may be limitations to the camera you are using. Most of us here have had success either with iPhone or DSLR cameras. I will give you one tip, lighting is easy to try, difficult to master.

I use my phone camera and I am able to take pretty good pics, at least I've been told a few times, and it's all about the settings. bigsilver is right about the flash. Your best bet is to take pics under a bright light and no flash. I actually have a normal corner lamp that's flexible and it has a 75 watt florescent bulb in it and I just bend it over on a corner table. Try out different settings to see what works. The same can be done with your camera. I have a ZTE Zmax Pro ($40) and it has a 16 mega pixel camera. I have it set on the highest resolution and I just set it to macro and get close enough to the coin before it loses focus. Afterwards I zoom in to get the basic size and area of what I want to post and take a screenshot and then go in afterward and crop the top and bottom till I get under the 300 kb. Practice a few shots until you figure it out. If you have a galaxy 7 you should have a pretty decent camera on your phone, prob better than mine if that's the route you decide to take. Good luck!
