Taking
pictures:
I really started seriously taking pictures back in 1970
when a friend of mine show me some of his pictures that were taken with
a SLR camera. Until then, all I had ever used was a cheap
point-and-shoot thing with a flash cube on top. I had grown to
expect my pictures to be under and over exposed, out of focus, not
centered and have poor or washed-out color. Now, I was seeing
pictures that rivaled National Geographic that someone like me had
taken! I was hooked! SLR's were expensive back then, but I
wouldn't settle for anything else, so I looked around until I found a
Russian-made SLR for $79. It was a SLR, but it was all
manual. It didn't even have a built-in light meter, but I ended
up learning a great deal about photography and I eventually did take
some amazing pictures. Over the years, I have since owned some
nice film cameras, but they all have the problem of not getting instant
results. You still have to wait until you get the pictures
developed to see what you have!
Then, about four years ago, I discovered digital photography. It
didn't have the resolution of film, but it was much sharper,
you could edit your pictures in the computer and best of all, you could
see the results instantly! I was convinced almost immediately
that this was the future of photography. Now, I wouldn't use
anything but digital, especially with the advent of the Internet.
If you want to take pictures of your projects so they can
be
published on a website or just for documentation, all you need is a
simple one megapixel or
higher digital
camera. Never use a flash. Always try to use natural
light. If it is a vintage radio, for example, place it in a
location where it would be found when it was first purchased, such as
in a living room, on a table, by the bed, in the kitchen, etc. then use
the available light. You probably noticed that I tend to do this
on the restorations page. I believe it gives the radios a soft
and warm setting that is realistic to the time when they were often
listened to. Regardless, remember that the best light
source is the sun. Take the item outside but try
to avoid direct sunlight by seeking a shady area. Sunlight coming
through a window also works well. The following picture was taken
in sunlight on a cloudy day. This reduces the shadows and
balances the depth of the colors:
Some small items, as well as homebrew projects, photograph well with
two or
three 100 watt quartz halogen desk lamps. I have three I
purchased at
Staples for less than fifteen dollars each that work very well.
With three, you can place them in a triangle pattern around the subject
and reduce or eliminate most of the shadows. The color
temperature of these are closer to natural sunlight, but you still may
need to do a little color balancing in the camera or later in the
computer because the halogen still gives the picture a slight yellow
cast as compared to sunlight. In the old days, with film cameras,
you would place a blue type "B" filter over the lens to
compensate. With most digital cameras, you just have to switch
the white balance to "incandescent", "tungsten" or a similar setting
and you have
corrected. Some cameras have a "memory" setting for white balance
which is really nice. With this feature, you just point the
camera at the background and record the best balance setting.
Later, you can recall this setting to take more pictures on the same
background. When finished taking the pictures, you can do the
final "tweaking" color balance in the
computer. More on this later.
When photographing your projects, try to get in close for detailed
shots of the components too. Don't forget the macro mode if you
have one. People like to see the parts you used and how you
installed or mounted them. Macro photography is a whole science
in itself, so I won't get into it, but with even the cheap digital
cameras, they usually have a built-in macro mode which simply let's you
focus in closer. Also, many of these cameras have an auxiliary
closeup lens available that you can attach to the front of the main
lens. These work fairly well, but you may experience some
distortion and
color fringing of objects. But, for the money,
they are worth it. If you do go this route, try to buy the
multi-element type as opposed to a single element lens. This will
help reduce the color fringing. When taking closeups like this, a
table top or
"mini" tripod is a must have item. It is virtually impossible to
hand-hold the camera still enough to eliminate a blurred picture,
especially when you are using 1/100 of a second or longer
exposures. When using these small tripods, be aware that many
cameras tend to be off balance when mounted with the lens pointing
down. My son learned this the hard way after his camera toppled
over and ruined a nice macro lens. Check for balance first and
add weight to one or more of the legs to compensate. I just place
a one pound roll of solder over one leg.
Backgrounds are one of the hardest things to come up with.
I have seen items for sale on eBay that look decent but have a trashy
or dirty looking background that really turns you off. Some look
so bad that you wonder if you are getting a roach motel if you purchase
the item. Many people drape a wrinkled sheet behind the item
which looks about as bad. I have sold a few items on eBay.
Once I listed an item that I had photographed on my somewhat messy
workbench in the basement. It sold for $18 and I had a little
over 50 hits on it. One month later, I listed an identical item,
but this time I photographed it on the back porch with my wife's
beautiful flower garden in the background. This time, it sold for
$32 and received over 160 hits! Was this a coincidence? I
personally like pleasant settings as backgrounds that look as appealing
as the item. With homebrew projects, this is not always
practical. A workbench where it was built would be acceptable if
it is clean and neat. However, a nice hand-built all-band
transceiver sitting on a bench made of orange crates with a pair of
bicycle pliers, a hammer and a beer can next to it wouldn't look so
good. Colored backgrounds work very well, but try to use colors
that compliment the subject and not detract from it. You can use
black or white, but be
aware that when using automatic digital cameras to take closeups on a
solid black or white background, there is a problem.
These cameras, when operating in automatic mode, want to correct the
exposure so as to get the best definition in the subject. A large
white background will fool this correction and you will get an
under-exposed looking picture with a color overcast. A similar
problem occurs with black which tends to look dark brown or some other
color instead of black. A way to
minimize this problem is to try to fill the frame as much as you can
with the subject and reduce the amount of background. Also, if
your camera allows it, switch to manual exposure and set the "F" stop
and time manually for the best picture. By using a solid color
background, you
can more easily edit it in the computer to reduce or totally remove
it. This produces an image that appears to be floating on the
page. Flat colors show
less reflections. Poster board works well.
You can also get a neat affect by using a velvety type of cloth and lay
it so that it is caressing the item like fine jewelry. I like to
do this with green velour. Sometimes the background can enhance
the item you want to photograph. For example, what about placing
your recently restored radio with some of the old tubes, you used for
restoration, laying in the background? Or, perhaps have an old
radio catalog or program guide laying in front of the set. This
gives one the impression of seeing a photo that was taken a long time
ago when these radios were popular.
Most people want to take the picture of an object dead-on, by placing
it in the center of the photograph. This is fine for many things,
but to make it more interesting, shoot at other angles to improve the
three dimensional effect or place the object off to the side so
you can capture the whole setting of the scene. Sometimes it's
better to not make your subject dominate the picture but blend into the
surroundings.
Once you have your photos, you can make them look better when viewed
online by using one of the many photo editor software packages to
sharpen, enhance the color, adjust brightness or contrast and resize,
among many other neat things. This
really makes a difference but don't go over-board. You are
enhancing the picture just enough to show what the item really looks
like in real life. You are only correcting what the camera is
lacking. If you go too far, you can misrepresent things like the
true color of the wood on a particular radio. People sometimes
want to see a radio in your collection so they can tell what the colors
are to
help them with their restoration. So, just a lite touchup
here.
If preparing the pictures for publishing on a website or just to e-mail
to someone, you must first resize them. For example, if you are
using a 5 megapixel camera and take pictures at the full resolution,
these would be way too big when placed on the screen. Also, a
picture taken at this resolution and stored as a Jpeg image would take
up about 2 megabytes of memory. Sending this to a friend as an
e-mail attachment or downloading it from a website would take a long
time, especially with a dial-up connection running at 56k. A good
size to use is 640 by 480 pixels. This provides a good size
picture and retains most of the detail without bogging down the
transfer of data. The above picture is 640 by 480. With
most photo editing software, resizing is done by simply typing in the
size, in pixels for one dimension, and selecting "OK". The aspect
ratio will be maintained unless you want a distorted looking image,
then you would type in both dimensions. Another way to resize is
"Cropping" Here, you can crop or trim off one or more sides to
better frame the subject. This doesn't distort the image, but you
may end up with an unusual aspect ratio on the final picture.
This can be bad, especially if you are going to find a frame for it.
The next step after resizing is to sharpen the image. Resizing
tends to make the image look slightly out of focus as compared to the
same image before resizing. This is why you wait to sharpen your
pictures until after you have resized them. Here again, I
wouldn't go too far. Just a little sharpening is all that is
needed. Anymore will introduce noticeable distortion. Some
programs allow you to selectively sharpen with a brush-like
command. This is handy when you only want to emphasize certain
areas of the photo.
Next, you can adjust the color balance and saturation. Each
picture will need a different adjustment of colors to look the best if
it needs any at all. The flowers picture above had plenty of
color saturation right out of the camera, so no adjustment was
needed. I usually only adjust the colors when I want
to compensate for lighting other than sunlight. For example, to
remove the yellow cast caused by incandescent lighting, reduce the red
level and/or increase the blue level. Everyone has their own
taste when balancing colors.
Do what looks good to you. The saturation simply is the amount of
color you want. This is useful when making pastels or bringing
out more color in a subject.
I usually adjust the brightness and contrast , if needed,
last. A picture that was slightly under or over exposed can
usually be corrected by adjusting the brightness and contrast.
This
photo was taken at 1280 x 960
resolution and resized to 460 x 345
with no other touchup or
editing.
The same photo after adjusting
the sharpness, contrast and color
saturation.
These
pictures were taken on a piece of poster board with the back curved
upward out of the scene. The lighting is from two 100 watt
halogen lamps placed in the foreground so the lighting appears to
diminish to nothing in the background.
Before
After
Here,
notice that the spot on the top left side of the box is removed along
with a light reflection on the tube glass. This was done with the
"Clone" function in the photo editing software. It allows you to
simply copy a nearby section of the photo to another area and cover up
imperfections. Most of the popular programs have this function.
As a final reminder, when
doing restorations, always take before
as well as after pictures and
every step in between, if you can. Documenting your work this way
helps others and it makes the project more rewarding when you are
done. Unfortunately, I didn't start documenting my work until
recently. I would love to have pictures of these sets before I
began the restoration work.
Have fun and don't hesitate to send me some pictures of your projects.
