Been practicing a little this morning with my camera. What are your thoughts on the photos below?

These are a big step backward versus what you were posting in January. What did you change? It looks like these were cropped from a larger image and then heavily sharpened.

The pictures in January were with my Sony Camera. Since January I have got an iPhone 5s. I did crop these images as that is what I thought I was supposed to do. I have not adjusted the sharpness. These were taken with the iPhone.

Are you as close as you can get to the coin with these shots? Did you downsize the image after cropping, or is this 100% pixel level? No camera produces sharp images at 100% pixel level, so your goal as a coin photographer is to make the coin on the sensor at least twice as big as you want to publish. 3x or 4x is even better but requires higher magnification than your iPhone can provide without add-on lens. You are using only one light, so there are blown-out highlights even on a worn Cent. Add a second light to improve the exposure evenness. You should also take care to make the coin level. Liberty should be flat, as should ONE CENT and USofA. It also looks like you're shooting at a slight angle, ie with the coin not flat vs the camera. This will create areas with poor focus, as is happening at the top of the obverse and bottom of the reverse. Hold the camera flat vs the coin to avoid this. So basically, just a couple modifications to how you're taking the shot, and some post-processing to improve on the basic results, and you'll have a much better image. Here is your obverse shot, with some rotation (lost a bit of the edge of coin in process...), some levels adjustments, and a 2x downsize:

Pics look grainy & out of focus.

I did not downsize after cropping. Is this something I can do with an iPhone? You are right about only using one light... I will have to buy another light. I will also make sure the camera is level with the coin. Thanks for all these recommendations.

What about now? I am still only using one light source but I did try a few other things. Also, I need to add that this picture was taken with the coin in an air tire. Any improvements?

Quote: I did not downsize after cropping. Is this something I can do with an iPhone? Were you able to crop with the iPhone? I assumed you used a program on a computer. Did you just snap the pic, crop it, and send it out to the forum? Is everyone LIVING in their iPhones now? That is a scary proposition. If you are expecting to do everything in your iPhone, then what you had initially is probably the best you can do. Quote: What about now? I am still only using one light source but I did try a few other things. Also, I need to add that this picture was taken with the coin in an air tire. Any improvements? Yes, better. Better focused. Will be even better with another light. But the pic is smaller. Did you move closer, and then downsize the image? What other things did you do versus the first images. This one is too dark, so you need to adjust gamma.

Yes...that is pretty much what I did. You can crop with the iPhone. I do not have a top of the line camera so I just use the camera on my phone. I think it takes good pictures considering its a phone.

try building a platform or bridge so that the iPhone sits 4" above the coin, then zoom in so the coin fills 3/4 of the screen.
your recent shots look like you were far away and tried to zoom in to make up for it.
not sure if the 5s camera is the same as the 4s but you should be able to get excellent (non-pro) results.

I was 4 inches and I zoomed in until the coin occupied 3/4 of the screen.
