In short :
We need images at a minimum of 2,500 pixels wide.
- Shoot your images in the highest camera resolution sensitivity (down to ISO 100)
- place your camera on a tripod and use the shutter timer to eliminate excess motion.
- Save your jpg-image WITHOUT compression.
- Make a picture of the item including the margins.
We can not emphasize enough the importance of good images! Better images do result in higher bids. An investment in a good High-Resolution camera is paid back quickly.
We recommend the Samsung NX 300, which is one of the best cameras available and surely less expensive then the Hasselblad we use!
The most basic promise of getting a good photo is to light your map or print with as even of a light as possible.
Do not make your image next to a window. Try shooting with your flash on if you do have not enough light. Making pictures in a room with TL lighting works best.
If you want to make good images read the following:
The best way to do this is with strobes and bounce umbrellas. Bounce umbrellas not only reflect the light backward, but they soften and spread it in the process. Soft light is very important.
You can use a monolight kit, consisting of 2 x 750 watt/second strobes (1,500 total), complete with umbrellas and stands. A set costs about $1,000.
If you are looking for something less expensive, I recommend a 'continuous light' kit. Something like THIS. A setup like this will cost about $400
The advantage of the strobes is a much brighter and much whiter light. Having a lot of light is important if you want a lot of detail, and the whiter light makes color balancing your image a lot easier. The strobes also have an adjustable intensity, which the continuous light does not. Lastly, strobes do not put out as much heat as the continuous lights. Continuous lights are commonly referred to as 'hot lights'......for a very good reason.
It may not seem like a big deal, but trust me, after 40 minutes under a 650-watt bulb, you WILL be sweating.
We use Profoto BIX studio Flash lighting.
So what if you can't afford either set-up?
You can achieve similar, albeit diminished, results with common lighting tools found at a Walmart or Home Depot.
I would recommend:
4 x clamp lights, like THESE
4 x 120W compact fluorescent bulbs, in the 5000K range, like THESE
2 large sheets of white foam core.
Total cost: $50
White balance is imperative! Look at your lightbulbs, and find out the exact color rating. The closer to 5000K (or above), the better.
Anything less than 4000K, and your image is going to be too yellow. Halogen lamps and TL lights are not suitable as they produce 2900K so, in addition, you have to use your camera Flash.
Once you know the temperature rating of your bulbs, set your camera to that exact white balance.
Your camera may only have a 'custom' option. In this case, you will need to photograph a 'grey card', in order to accurately calibrate your camera.
Positioning of your lamps
Once you have the necessary lights, the next step is positioning. I photograph my maps at a 90º angle. To either side of my map, is one of my strobes. I aim the strobes AWAY from the map and let the umbrellas bounce the light BACK toward the painting at roughly a 160º angle. This is called a 'raking' light.
This angle is extremely important! If you place your lights in such a manner that the light strikes the object at an acute angle (less than 90º), the light will bounce off the painting, and back into the camera lens... causing glare. Glare, is quite literally a reflection of the light source on your painting's surface. The more acute this angle is, the worse the glare will be. An on-camera flash would result in the absolute worst glare possible since it is striking the surface at an angle of 0º degrees.
Once the lights are in position, I set up my camera and tripod. Now cameras and lenses are a great big can of worms that I am not going to open here. We could talk about that for days! Sufficient to say; the better camera you have, and the better lens you have, the better your image is going to be.
I shoot with a 50-100mm zoom lens. A zoom lens is very practical so you do not have to move the camera forwards and backward.
Many people assume that narrowing your aperture to F/22 will always give you the crispest shot. This is not true. Any adjustable zoom lens has a 'sweet spot', a perfect combination of aperture and zoom where the light is most focused. (Think of it as the sun through a magnifying glass). This sweet spot is usually somewhere in the middle of a lens' zoom/aperture range. To find it, you need to experiment.
Check your camera's settings, and try to find the highest quality/compression possible. Many high-end cameras offer a RAW format option.
JPEG is short for Joint Photographic Experts Group, and is the most popular among the image formats used on the web. JPEG image is not as sharp as the original image. The colors are paler and the lines are less defined and the picture is noisier. Always safe your items WITHOUT compression.
Below a sample of JPEG compression of varying levels, from highest to lowest. Almost every digital camera can shoot and save in JPEG format. Remember to save or convert images WITHOUT compression.
If possible, shoot in RAW format as it does very little compressing and allows you to alter your exposure/color settings after you shoot the image.
Afterward, you can convert to JPEG or TIF format.
TIF: This is an image format file for high-quality graphics. Popular among graphic artists, the publishing industry, and both amateur and professional photographers in general.
Always shoot at the lowest ISO possible (Sometimes called ASA). I typically shoot at 50 or 100 ISO. If you go above 400, you are likely going to get a lot of noise in the dark areas. It's better to have a really slow shutter speed than to try to bump up the ISO.
Do not attempt to handhold a camera when reproducing your work. Even the subtlest of vibrations will ruin the detail. In fact, not only do I use a sturdy tripod, but I usually set my camera on a delayed timer, because the simple act of even pressing the shutter button by hand is often enough to shake the camera. Likewise, if your camera lens has a Vibration Reduction feature, turn it off. If there is no vibration, that feature actually does more bad than good.
High pixel-count cameras like the Nikon D800 and Nikon D800E, for example, need to be stock-still and used in mirror lock-up or exposure delay mode to get the benefit of their resolving power if the shutter speed is below around 1/125th second.
If you are looking for a good, and free photo-editing program; we would suggest GIMP or the commercial software Photoshop by Adobe.
If cropping your photos, please show at least 1cm of a margin, or even better - full margins. As a general rule, we crop outside a Medieval manuscript page leaf and show both sides!
Tethered shooting is a photography technique that has been practiced by many professional photographers for years. In short, tethering allows you to connect your camera to a computer or tablet and almost instantly view your digital images on the device within seconds after it is captured.
We need images at a minimum of 2,500 pixels wide. Shoot your images in the highest camera resolution sensitivity (down to ISO 100) and place your camera on a tripod and use the shutter timer to eliminate excess motion. Save your jpg-image WITHOUT compression.

There are several good cameras on the market for 500 - 750 US$.

When your item has text on the verso, or repairs we recommend adding an additional image. When you are selling an atlas or book we recommend adding images of the binding, title page, and some illustrations. You are able to upload up to 20 images.
Please upload one HR image including the margins of the item.
We do not add images of multiple parts of the main image.
In the consignor center, you can follow the buying and bidding process of your items.
