Part 11 - Photographing Silverware

Although it doesn't quite fit in to the subject of food photography, a table setting is often included in a closeup food photo.

Flatware can be a difficult subject to photograph due to the reflective surfaces, especially when dealing with spoons, where the room surroundings are often reflected in the bowl. I'm going to show examples taken in daylight by a window using white and black backgrounds, with and without a tripod.

Here is my setup, using one and later two styrofoam reflectors on the dark side.

Here below are examples using a black velveteen background.
The first photo shows a bad example of how a handheld camera shot at this arrangement of three spoons reflects my hands and camera.

In the next two photos, the spoons have been arranged differently so they reflect more the surrounding room.

Here below on the left is another example of a bad reflection. Although the pattern of the silverware shows up nicely, the bowl again reflects the photographer.
The photo on the right shows a closeup using macro mode where the pattern is the prime object.

The picture below is not a photo at all, but was rather a scan done on a flatbed scanner.

Using the Tripod and Self-Timer

When you have your camera set up on a tripod you will surely be able to take clear, sharp images of something as fine as silverware, where you want to display the pattern clearly.
In order to keep yourself and your hands out of the picture, using the tripod and the self timer allows you to duck out of the way so you are not reflected in the silverware.

Here below is the sequence for doing this:

1) Photo left - set up the flatware on black velveteen, black or white paper or cloth and with camera on the tripod, adjust the level of the view and zoom a little until you are happy with the image in the viewfinder or LCD screen.

2) Photo right - Set your timer for the delay in seconds, enough for you to move away from the camera. Press the OKAY button to confirm your choice.

3) Press the shutter halfway and when the green focus light gives a small beep and a steady green light... press the shutter the rest of the way down.

hand on
You haven't yet taken the picture but the camera is now counting down the number of seconds you have set, so move yourself out of the way. The shutter will open and the camera will take the photo without your touching it.

Remember that if in step 3 the green focus light blinks rather than stays steady, the camera can't focus at the distance you have set.
Change your zoom level (more zoom or less zoom) or if necessary, move the tripod further away.

Here's the photo just taken in the example above using tripod and timer where the reflection in the spoons is that of the window.

Photographing The Moon

For a change I'm taking a little break today and the topic will not be about photographing food. That is, not unless you still believe the moon is made of green cheese! But it may be of use if you want to take photos of the moon and have not yet tried to do so with a point and shoot camera.

Last night, January 29, 2010 was the brightest the full moon will be this year, due to the fact that the moon was in perigee, the part of its orbit closest to earth. The coincidence of the perigee and full moon is something which occurs only once or twice a year.

full moon Manual (M)...f/4.5...1/160...ISO 50

When I heard that the night was to be special, I went outside around eight-thirty in the evening to have a look and saw the full moon shining brightly in a clear, cloudless sky. So I knew this was to be a rare opportunity to take a good moon shot, even though I don't have a telephoto lens. I used my Olympus SP-560UZ point and shoot camera with an 18x optical zoom, set it up on a tripod and took several shots at different exposures before being quite happy with the one above.

So I would like to pass on the little bit of my experience I gained last night.

The moon is much brighter than you may think, so don't set your camera for a night shot or a long exposure or you will get a white blob surrounded by a white haze rather than a sharp image with visible moon surface features.

Here's what I learned from last night's trials and errors:

Use a tripod.
This will ensure a steady camera and a clear photo.

If you have a point and shoot which has an option for MANUAL (M on the mode dial), use that setting so you can set both the aperture and shutter speed. Otherwise try a daylight semi-automatic setting. Open your OPTICAL zoom to full, but don't use digital zoom.

Here are examples of what you may get using MANUAL at different shutter speeds with apertures f/4.6 and f/4.5:

moon at 1/4 sec f/4.6... 1/25 sec... ISO 100

This above taken with a slow shutter of 1/25 second. You see the brightness of the moon as a white blob with surrounding haze.


moon at 1/80 sec f/4.5... 1/80 sec... ISO 100

The next one above, was taken with a faster shutter speed of 1/80 of a second. You see the focus is getting better and the haze has nearly disappeared, but it is still too bright.

moon 1/125 f/4.5...1/125 sec...ISO 50

The third one above is almost right, with an aperture of f/4.5 and a shutter speed of 1/125, ISO 50. If you are able to adjust the ISO on your point and shoot, take it down to the lowest setting as you are photographing a bright object that doesn't need a boost in brightness. A lower ISO also insures less noise or digital static in the picture.

Finally I set the shutter speed a little faster, to 1/160 and am happy with the result in the photo at the top of the page, as moon features are quite visible.

I did a little post editing with CodedColor, an inexpensive editing program, using a minimum of Levels and Unsharp Mask, and adding the borders and watermark.

I hope you will find it as easy to do with your camera.

Good Luck!

Part 10 - Self-Timer and Flash

Hi again everyone. I'm back with another entry on how to use your digital camera for taking tabletop photos.

The Self-Timer Function

This function incorporates a pause after you have pressed the shutter button. The shutter doesn't open right away, but rather waits according to the length of time you choose before taking the picture.

Perhaps you are accustomed to using the self timer so this will be nothing new for you, but if you have hesitated to try this very useful function on your P & S (point and shoot) camera you will be pleased to see how easy it is to not only to put yourself into a picture but also to sharpen some of your tabletop photos by avoiding camera shake when you press the shutter.

Here is the icon for the self-timer and where it may appear on the back of your camera body:

And here are the settings on my camera, which may be different on yours:

And as seen displayed in the camera menu after entering the self-timer option you could have: Off, a pause of 12 seconds or a pause of 2 seconds before the shutter opens and the photo is taken.

The procedure to use the self timer couldn't be simpler.

Assuming the camera is either firmly attached to a tripod or resting on a stable surface, find the self-timer menu and decide how long you want the camera to wait before it takes the picture.

If you are going to jump into a group photo, then give yourself the longest time in order to settle yourself comfortably in the photo, eg 12 seconds.

On the other hand, if you are going to use the timer to avoid possible camera shake during a tabletop photo shoot while you stand behind the camera, then set the shortest time lag. Then press the OK button.

Press the camera shutter button half way down and look to see that the green focus light doesn't blink. (If it blinks then you have to move the camera further or closer to your subject since blinking means the camera can't focus at the distance you have chosen.) When the green light is steady, press the shutter button all the rest of the way down. Take your finger off the camera and either run to join your group or wait without touching while it beeps a countdown and takes the photo. You've just used the self timer!

By doing this you have avoided any possible movement of the camera that could occur as your finger presses the shutter button.
While the camera is in countdown, you can do other things, such as holding a white reflector near your subject to improve the lighting.
That's another advantage to using a tripod. Your hands are free while the camera takes the photo.

The Flash Menu

The flash menu is usually accessed by pressing the lightening bolt flash icon on the back of the camera touchpad.
See again the top photo of the back of the camera with red arrows. Pressing the touchpad at that point brings you into the flash menu, where the icons are quite easy to understand.

You may need to press the flash pop-up button (3rd photo) to begin using the flash.

flash 1
The flash will fire automatically when there is insufficient light. The camera decides if you need flash or not.

flash 2 Red-eye reduce mode. The camera emits pre-flashes before firing the regular flash in order to avoid red-eye.




flash 3

Fill-in flash. The flash will always fire regardless of light conditions. Useful for eliminating deep shadow on the subject's face when subject has back to sunlight, or in similar circumstances where you want to eliminate shadow.


flash 4 Always emits pre-flashes for red-eye reduction.


flash 5

Flash off. When the lightening bolt is surrounded by a circle or square, it means the flash will not fire even in low light conditions. Remember that a P & S camera flash will make your food look very flat and unappetizing, so don't ever use it for food photos.

I think that's enough for today, so I'll save the tutorial on photographing silverware until next time.

If you have questions please ask here or PM me.
So thanks for joining me.
