Several photos of the same 1909 VDB LWC obverse, with adjustments to position of lights, sharpness, contrast, and exposure compensation. Questions: 1) Do you see any problems with the photos that my untrained eye is missing? 2) Do you prefer one or more of the photos over the others (and why)? - If it's simply a matter of subjective preference, that's helpful to know. Thank you! ~ Mark PHOTO #1 - "Normal", i.e., both lights pointing down (at about 11 o'clock and 1 o'clock), ~125mm from coin. Tv(Shutter Speed) 0.4 / Exposure Compensation: 0. Sharpness: 3. Contrast: 0. Saturation: 0. Color tone: 0. (Saturation and Color Tone are the same for all photos.) Other camera info & settings below (after all photos).  PHOTO #2 - Left light in 'normal' position; Right light at 2 o'clock, ~400mm away from coin. Tv(Shutter Speed) 0.3 / Exposure Compensation: -1/3. Sharpness: 3. Contrast: 2.  PHOTO #3 - Left light in 'normal' position; Right light at 2 o'clock, ~400mm away from coin. Tv(Shutter Speed) 1/4 / Exposure Compensation: -2/3. Sharpness: 5. Contrast: 2.  PHOTO #4 - Right light in 'normal' position; Left light at 2 o'clock, ~400mm away from coin. Tv(Shutter Speed) 1/5 / Exposure Compensation: -2/3. Sharpness: 5. Contrast: 2.  PHOTO #5 - Right light in 'normal' position; Left light at 2 o'clock, ~400mm away from coin. Tv(Shutter Speed) 1/5 / Exposure Compensation: -2/3. Sharpness: 3. Contrast: 0.

First pic seems the best. It shows more of the coins details.

I am no pro,all pics look a bit out of focus to me. Try a different color background,18% gray I think is recommended. John1 |

First is best, but the way the light is shining on the coin is not consistent with 11 and 1 oclock. 11 oclock should have lit the top and back of Lincoln's head, while 1 oclock should have lit his forehead, cheek, and top of chin. It almost looks like you're lighting from 2 oclock and 4 oclock, so it's hard to judge.
For settings, what are your sub-settings for the Standard style?

If that doesn't work, I'm starting to think it's my eyesight because my pics being out of focus has been a continuous problem. Fortunately, I see my ophthalmologist in a couple of weeks.  |

I'll have my daughters and a friend look at my setup as I admit I am 'spatially challenged' so I might be judging the light positions incorrectly. Quote:

You may want to try only one light at 12:00. May also need to filter that one light. John1 Edited by John1

Lighting is key and with that said photo #1 is the closest. The positions of the lights may be 11 and 1 but it's not balanced as such at the surface of the coin. The 1 position is creating some hot spots and the 11 position barely apparent. What type of lights are you using?

Just a little optimization of light placement, and a little post-processing, and you're golden.

Actually, there is one more thing...the coin is not level in the pic. LIBERTY should be flat. Pet peeve of mine...Ray
