MAKING THE BEST USE OF DEPTH OF FIELD
As illustrated in the following chart (Figure 18), the depth of field of focus increases in proportion to the smallness of the opening or f stop, and decreases in proportion to its largeness. It is this range that is commonly referred to as the depth of field.
Consequently, apart from the fact that you will have to make sure your subject is in sharp
focus, give full consideration to this important factor. For instance, in taking a picture of a person, the blurring of the background by using a wide opening will make the person stand out. On the other hand, when taking a group picture where people are standing in rows a small opening
becomes necessary to ensure that the focus is sharp on every subject.
 |
 |
| Thus, if you set the opening at f/8 and the distance scale at the red dot, everything will be in sharp focus from 10 feet to infinity. (See Figure 18.) For taking sequence shots referred to in a subsequent section this will prove of immense advantage.4www.butkus.org | |
FOCUSING THE CAMERA
1. As illustrated in Figure 19, place your right index finger lightly on the shutter release button and with both hands turn the Duo-lever focusing control.
2. Usually the image as seen through the view-and-rangefinder will appear " double "
in the center tinted square, which means that the subject is not in focus. When this is the case, move the lever so that the two images merge, or, in other avoids, become superimposed. The subject is
now in sharp focus.
TAKING YOUR PICTURE
To muddle means the possibility of missing a shot; so let us do things systematically so as not to miss our chance.
1. Get your light value set.
2. Decide on your depth of field and shatter speed.
3. Wind your film, which cocks the shutter, too.
4. Focus your subject.
5. Release the button and take your picture.
 |
Steady your camera when you shoot by resting the camera against a part of your face and hold your breath for a moment as you shoot. (See Figures 23 and 24.)
The camera is built in such a way as to prevent the taking of double exposures and the skipping of a frame. In other words, there is no danger of DOUBLE EXPOSURES or BLANKS. Do not advance the film until the shutter has been fully released. This is particularly important when using the bulb or slow shutter speeds. After you have advanced your film, which cocks your shutter automatically. it is highly advisable not to change shutter speeds between l/l0 and 1/25 and between 1/250 and l/500. Do not keep pulling the triggermatic-action lever when the camera is unloaded as it may put the camera out of order.4www.butkus.org The only absolute guarantee against taking shots that are spoilt owing to any jolting of the camera is the use of the tripod. For any speed slower than 1/25 we recommend the use of RICOH " CINE " TRIPOD. When you use a self-timer a tripod is a necessity; and you will find your RICOH " CINE " TRIPOD ideal, as you can direct your camera toward any direction while it rests fitted on to it. It always pays to make sure that your important group and other pictures are not spoiled. |
 |
When using a self-timer or a shutter release, screw it on to the shutter release button groove. The RICOH
SELF TIMER, which may be procured from your dealer, gives a wide margin of 7 to 15 seconds before the shutter is released. The length of time depends on the extent to
which it is wound; so that you could experiment with it when the camera is unloaded and remember just how far you should wind it.

TAKING SEQUENCE SHOTS WITH THE TRIGGERMATIC-ACTION LEVER
The Triggermatic-action lever is an outstanding feature of this miniature camera, adding further to the maneuverability of
an already maneuverable camera. ( Only a full pull on the triggermatic-action lever, which takes but a fraction of a
second, and the film is advanced by a frame and the shutter set.
This LEVER-PULLING AND) SHUTTER-RELEASING ACTION is so rapid and smooth as to be a feature
unequalled bi other cameras. If you bring the red dot on the distance scale to the
center and set the lens opening f/8, its versatility is greatly increased,
ENABLING THE TAKING OF PICTURES AT A RATE OF10 IN 10 SECONDS.
WHEN YOU HAVE FINISHED TAKING PICTURES ON ALL YOUR FRAMES
When you have come to the end of your film, it will refuse to advance any farther.
If you pull your lever against this resistance, the perforations will tear and you may
even spoil the last part of your film. In order to prevent such a mishap it is wise to go a little easy on your lever after your 20th
exposure or 36th exposure, depending on the number of exposures your film is expected to take. With most films
1 to 3 extra pictures can be taken than indicated on the film package.4www.butkus.org

In rewinding the film--to not open the back of the camera until this is completed--flip up the rewinding crank fully,
shift the rewinding release button on the back-side of the top toward the letter "R" as indicated, and rewind in the direction of the arrow on the crank. Do not let go the rewinding release button
referred to, while you rewind the films already exposed, because if you
do, the film will tear owing to the locking of the sprocket. (See Figure 27.)
When the film has been fully wound back into the film cartridge, the crank will become extremely light.
Open the back of the camera and take out the cartridge carefully. The taking off of the back cover will cause the film counter to
return n automatically to S (Start). On no account open the back of the camera until you feel assured the film has been fully rewound. Neither should it be opened in direct sunlight, as strong
light call pierce into the cartridge through the narrow slot.
YOUR RICOH FLASH GUN
The flash gun is your answer to taking pictures at night, especially of subjects that are in motion, to taking a portrait against the light, and to softening the too-sharp contrast in strong sunlight.
We have flash bulbs of various kinds, such as F. M, or Strobe. On an ordinary camera there is no course but to choose the kind of bulb for which the synchro mechanism is made. The Ricoh De Luxe L, however, is provided with M, F. and X
settings, making it possible to use all brands of flash bulbs. Set
the synchro lever to M, F, or Strobe, according to the kind of flash bulb as indicated on the wrapper or box, and you will be ensured of your
flash light and shutter opening fully synchronizing from 1 to 1/500, according to the conditions indicated in the following table, which illustrates the
relation between the kind of bulb and synchro setting.

There are many kinds of flash gun; but RICOH 500 is provided with a CORDLESS FLASH CONTACT on the ACCESSORY SHOE, so that if you slip on your RICOH FLASH GUN BC-605, it will save you the trouble of attaching a flash cord on to the flash terminal. No dangling cord, and no failure in charging the bulb through faulty connection is your gift that comes to you in your RICOH FLASH GU N BC--605.
In taking pictures with flash, it is vital that the exposure is correct. Otherwise, underexposure or overexposure will result, the danger being even greater in most cases than in day light conditions whet e the light is even. Any variation in the distance from the source of flash light to the subject results in a proportionate and great difference in the amount of light. Thus, it is extremely important to set the correct F stop according to the distance from the subjects4www.butkus.org
To put it simply, granting that different types of bulb differ in their luminosity, the closer the subject the smaller must the opening be and vice versa. With any packet of flash bulbs you bay you will find a table of what are technically referred to as GUIDE NUMBERS. If you divide the number which fits your case by the distance in-feet, the figure you get shows the f stop opening which is required for your shot. For example, if your film has ASA 100 Exposure Index, you look for your GUIDE NUMBER that is given for this Index. If you wish to find out the distance-in-feet for a given f stop, divide the GUIDE NUMBER by the number that stands for the f stop.4www.butkus.org |

ACCESSORIES
A number of accessories for this camera have already been mentioned in the foregoing pages, besides which we are happy try offer you the f allowing, manufactured specially by our Am.
RICOH LENS HOOD (43 mm)
| Our lens holed dues the important job of cutting off unnecessary light or glare that may damage a picture. It is for this reason that the inner side of the hood is coated with black. Our hood is handsomely made and fits snug into an equally handsome leather case. |  |
RICOH FILTER (34 mm)
 |
You, Ricoh filters ensure the taking Of pictures with the right tone arid texture, and are a NECESSARY PART of your picture-taking equipment. The most greatly used of the various filters are the UV arid Y1 and Y2 filters. The yellow filters help to bring out red and yellow tints and to tone down the blues, so that clouds are made to stand out against a filter-darkened sky. The degree to which a sky may be darkened will depend on the darkness of the filter and amount of exposure. When no filter is used, the sky is more than likely to come out flat. |
THE CARE OF THE CAMERA
The camera is a precision-built instrument that requires the greatest care and attention.
1. The lens is the life of the camera, so that it requires the most delicate handling. Consequently, do not touch it unless it is dusty or smudged. In removing dust or grit An not wipe, but first use a soft lens brush and, if necessary, wipe gently
with a silicone cloth. When a camera is brought into a warm place from a cold place suddenly, it will get clouded. So wait until the camera and lens temperature reaches the room temperature, and the lens will clear up.
2. When you have taken pictures by the seaside or on wet weather, see that it is clean before putting your camera away, and wipe it, if necessary, with a piece
of' soft cloth.4www.butkus.org
3. Do not leave the shutter cocked over a period of days, as this will weaken the shutter spring.
4. When not in use, place the syncro setting at X and the shutter At
1/25. This is important in preserving the life of the camera.
5. When putting the camera in the case, set the distance at infinity.
6. In order to keep the camera from getting damaged through exposure to moist
atmospheric, put it in a box arid in a dry, cool place. A chemical substance that will keep the
air dry may be obtained.
