Quote: Every time I visit HA.com to browse their coins it is fascinating how consistent the photos are no matter what the substrate being photographed is.
I personally would like to find out a few tips insofar as:
1) How does HA maintain a photo's resolution consistent (w/o excessive pixelation occurring) when one zooms in on a photo using an index finger-operated mouse wheel?
2) And when one does zoom in very tightly (enlarging a coin to fill up an entire laptop's screen) in this manner 'all' of the various depths of a coin's surface have perfect clarity w/o any blurriness. What process do they use to achieve this result?
3) Finally, would any of CCF's coin photography threads have proven/tested current setups and discussions (with photos and a short video of the zoom-in process) from members that have successfully replicated these cool characteristics via reasonably affordable equipment and feasible processes etc.? mdpm...the equipment listed in the "<$350" and <$400" threads is perfectly capable of doing all of the above, or even way better. Based on what I see at the HA site, they push their aperture down until there is a little bit of diffraction blurriness, but not enough to be annoying. They also light the coin very effectively. They also likely have a fairly complex canned/proprietary post-processing routine using PhotoShop tools. But with good lighting technique, and <$350 worth of equipment, you can do just as well.

Hello, I found this discussion really interesting. Do you know what type of lamps does HA uses for shooting? The photos are not showing up anymore. Can you post them again? Thanks, David.

Thanks for bumping this thread up but I doubt the photos are retrievable. Photobucket decided to start charging for their image hosting services several months ago. Rendering thousands of pages on this website useless. Probably needless to say but if you want to post pics on this site in the future, just upload them here directly And  to CCF!

dal,
e ótimo ter você como membro CCF
translated 'it's great to have you as a CCF member.'
For starters it always made me feel more comfortable in non-US countries when I heard speaking or saw writing for the initial contact from a foreigner trying to communicate with me in English.
However, I always knew I would never, ever be proficient in anything but English but just the attempt made me feel that the other individual truly wanted to welcome me to their group.
We hope you continue on for many more posts going forward with CCF :)

Thanks Jbuck, MikeF and Mdpmedia for the welcoming messages. I´m very glad of joining this group. MikeF, I understood what you say by photobucket and I suppose the best thing to do now is trying to connect with the original poster and aks if he/she still has the photos. David.

Search around the web, several people posted photos from those tours. Some of them will still remain.
There was I remember a whole thread spawned discussing how they did it - consensus was is was for consistency and even lighting, not beauty.

BTW this is not much different than the "diffusion at the lens" concept, but on a bigger scale...

westcoin, thank you so much for the photos. Did you have a chance to observe what type of lamps (as well wattage) does HA uses for shooting? I wonder also if the diffusors are plastic or paper. At that distance, the lamps can´t be too hot otherwise they would be burned.

dal, The diffusers were plastic sheeting clamped to a simple frame. Nothing special about them really, one could probably use vellum paper or similar plexiglass in translucent form. I've successfully used a cut up milk carton in the past.
I would guess (was a professional photographer for over a decade) they wattage is either 500 or 1200 watts lamps, not sure the power settings used, but probably they would vary for each different station (copper, silver or gold) and depending on how close to the windows the station is at (ambient light) there was no real control of the ambient light at all in the room which surprised me. The lamps are only at power when firing the shot, you can run them at a lower level to see shadow placement. I assume they calibrated each station, camera lens setting, that would make sense as they are trying to maintain a constant equal level and lighting for each coin they shoot, with an ultimate goal of going to their website for auction and printed catalog.
