Why are there different types of film? Why do my enlargements look different from the original set of prints?
Well....that depends..... Are you taking pictures inside or out? If inside, are you using flash or available light (or in some cases available dark)? And how far from your subject will you be, how powerful, or weak, is your flash? If you are outside, are you at the beach, in the city, or in the forest? Are you taking "snap shots" for you photo album or are you taking "artistic" photos you want to frame and hang on your wall. Then there's the matter of your equipment. What kind of camera do you have? Is it a SLR with a zoom, interchangeable lens, and adjustable shutter speeds or is it a do everything "point and shoot" with automatic shutter and aperture settings. Are you taking pictures of still or moving subjects? Do you want color prints, slides, or black and white prints? Sound like a lot to think about? Well it's not really, and the choice of film isn't that complicated either. To begin with, think about where you will be for the majority of your shots, mostly inside, mostly outside, or about even for both. For each situation, will it be well lit or not so bright? If you have a flash it's just like carrying your own portable sun. So wherever you are with a flash, it's just like being outdoors on a bright sunny day, if your flash is macho; or like being outdoors on a slightly cloudy day, if your flash is a little wimpy. But if you don't have a flash, you will need a higher speed film that's more sensitive to light for inside or for under dense foliage. Next decide what speed film will fit the situation. Film speed, or ASA now called ISO, is a measure of how sensitive to light you film is. Slow film is less sensitive to light than fast film, and has a lower ISO number. Slow film (100 or less ISO) is for really bright light and faster speed film (400, or higher ISO) is for low light. And if you're dividing your shots between dark and light, a medium speed film (200 ISO) will be what you need. In spite of what a certain commercial running on tv says, you can't get great results from one film speed in all lighting conditions, but you can get acceptable results with a general purpose speed film. Along with the light level you must think about how important sharpness and color are to your photos. Lower speed films are sharper and have more vivid color than the faster films, but if you need the speed for the lighting conditions you will have to sacrifice some sharpness to get the image. I like to always be prepared to get a shot I would like to hang on my wall or give as a gift, so I try to keep slow film in my camera and a short roll of fast film on hand as a "just in case". While you can tell a difference between snap shots on slow film and snap shots on fast film, today's better films are very sharp compared to older films and just about any speed will do for snap shots. But for enlargements of 8x10 or bigger, 100 or 200 speed films are best. Slower speed films contain less silver, that's why they are less light sensitive, and are less expensive. So using high speed film is less cost effective. If you are dealing with low light, without flash, high speed films are usually a necessity. As I said above, a flash is a small portable sun. Just as the distance from the sun affects how bright it looks, so does the distance of your flash from your subjects affect how much light gets to your film. When your subjects are farther away from your flash, and your flash is not a He Man type flash, you can help it out by using a higher speed film. For instance, a point and shoot camera's flash with 100 speed film will only illuminate subjects to about 8 or 10 feet away. 200 speed film will make your flash "reach" 12 or 15 feet and 400 speed film will extend it's range even farther. For best results with most point and shoot type cameras we recommend 200 speed film. This also is a very good general purpose film if you will be inside and outside, and for flash pictures both near and far. Last of all, what do you want for your final result? All of the above will apply whether you shoot color print film, black and white print film, or color slide film. You can get reasonably good b&w prints from color print film but you usually can't get good b&w prints from slides. You can get reasonably good slides from prints and good prints from slides if the slide is good. Poorly exposed slides do not make good prints. In general it's always best to shoot the type of film you need rather than to try to change the results later.
So here's the routine: First, where will I be? Bright light : 100 or 200 speed film Second, if with flash, how far away will I be? Small rooms (apartment) : 100 or 200 speed film Third, do I want slides, color prints, or black and white prints? Color print film Not sure of any of the above? Use 200 speed color print film, or if you are the timid type, use the less sharp and higher contrast 400 speed film. See, just three (or one) easy steps that will save you money and frustration. Why are there different types of film? Each film will have it's own pros and cons. In general, slow films will
give the best color, contrast, resolution, grain structure, and usually
be less expensive. High speed films will allow you to shoot in low light
or freeze the action of fast moving objects, but will have higher contrast,
less intense color, and cost a bit more. Grain refers to the size of the microscopic balls of silver that are in the film’s emulsion. Higher speed films are more sensitive to light and have larger grain than the smaller grain in lower speed films. When someone refers to a picture as being grainy, they mean that the picture has a pebbly, or rough and undefined look, when it is enlarged beyond the film’s capability. Slower speed films, because of their fine grain structure, can be enlarged more than fast films before grain becomes a problem. Some newer and better (read more expensive) films, such as the Kodak Royal Gold and TMax films, have what is called T-Grain technology. This means that the microscopic balls of silver have been sliced into tablets. This allows the silver particle to be flatter, without the hills and valleys of the balls, and give a higher resolution than the previous traditional films. I like these films a lot, especially for low light situations. I recently shot a job for someone, and had to use 400 speed film and do 8x10 prints for them. The 8x10's were extremely sharp with no sign of grain. For situations like that, you can't beat the T-Grain films. Another great use for the T-Grain films are when you want a very large photograph. Most 35mm films are limited to enlargements of no bigger than 16x20. And that usually means that everything was done right, low speed film, tripod, critical focus, high shutter speed, etc. If it's a high speed film, handheld, and slow shutter speed, you probably can't go bigger than 8x10 without the flaws showing up. But if you want something really big, especially from a high speed film, then a T-Grain film may be what you need. I've see 20x30 enlargements from T-Grain films that were shot handheld and looked very good for that size enlargement. To recap the basics, low film speeds give you: lowest cost, sharpest image, lowest contrast, and best color. High speed films make picture taking in low light and indoors without flash easier but, have higher contrast, less resolution, slightly less intense color, and cost more because of the extra silver in the emulsion. Why do my enlargements look different from the original set of prints? Many people think that the first print produced from their
negatives is the correct rendition of that negative. Well it may or may
not be the best possible print from the negative. In a color negative
there are no absolute values. In other words, you can tell that something
in the negative is green, but you cannot tell how green, or what shade
of green, it is. The level of green is deduced by how other things in
the picture look. So the first print produced from a negative is simply
an educated guess as to what the photographer saw when shooting the negative. We strive to make the best possible print, but some subjects can look good with a wide variety of renditions. Sunsets and flesh tones are two perfect examples. Sunsets are usually a monochromatic scene and can be made to enhance any one color of the spectrum. You can make a sunset be anything from predominately purple to predominately green, if you so desire. Flesh tones are also tricky. Everyone knows what an average flesh tone looks like, but without knowing the person involved, a printer doesn't know the exact flesh tone of the person in the picture. Once again the printer must make an educated guess based on other information in the scene. Anytime that you have a print that you like, it is a good idea to send it with the order as a guide print, so that we can match the color and density. We always hope that we are getting a result close to, or better than, the first 4x6 print but we really have no way of knowing without being able to see the original print. The vast majority of the time we do get a result as good or better than the original print, but sometimes unfortunately, we do not get close to the original print. There is a lot of interpretation involved in producing a color print, and try as me might, we sometimes don't interpret the image the same way as the previous print was interpreted. There are also differences in the paper and chemistry used in making the print. Like films, papers have different color and contrast characteristics. So an image produced on a type of paper that accents the red colors in a negative will look different from a paper which may accent the blue colors of a negative. So even with a guide print, a printer may not be able to match your guide completely. Most 4x6 prints are done on a paper with a high contrast to make the prints taken with an inexpensive snap shooter camera look sharper. This helps negatives that may not be as sharp as negative taken with an expensive 35 mm SLR. A larger image however, should be done on a lower contrast paper in order to show the fine detail and wide tonal range available in the negative. If given the 4x6 print, with which you are satisfied, it should be no problem to at least come close to that in a larger print. There will always be minor differences due to the differences in paper, the aging of the negative, and sometimes I think the phase of the moon. Just kidding, but sometimes a print will just never look right no matter what we do to it. This is probably due to something going on in the negative itself, like premature aging due to improper development, or exposure to chemical fumes such as moth balls or other household products. To get the best possible enlargement from your negatives you must know what you want, have a printer willing to work with you to achieve it, and be able to convey your view of the print to your printer. This is usually best done by a guide print. You can even send a bad guide print, one too yellow for example, with a request that the enlargement be less yellow. Most of all, you need to have an experienced printer who knows what the negative and paper are capable of producing. When you find a good printer you will quickly realize that they will produce for you, the best print from your negatives with little or no input for most of your negatives, and only need direction for the really tricky scenes. Cropping is essentially creating a new picture from an original picture by cutting out or ‘cropping’ the top, bottom, or sides of the picture. You can use cropping to get rid of things in the picture that you don’t like or you can crop to a single person in a group shot. Cropping is also used when a print of a certain size needs to be converted to a different size print. For example if you have a 4x6 print and want to produce an 8x10 of the same picture, you will need to crop off some of the top and bottom to make the picture fill up the whole 8x10 size. This occurs due to the size ratios of the different prints. If you want to try out cropping, most all photo editing software comes with cropping tools for you to use.
