Digital Differences While you can use lenses designed for "full-frame" 35mm-sized sensors on smaller-format (APS-C) sensors (subject to the telephoto, or magnification effect), the converse isn't true. For example, the Canon EFS 18-55mm IS, included in the EOS Rebel XS kit, is designed specifically for use with APS-C-sized image sensors, like those used in the Rebel series.

Photography is a hobby of mine and I recently began researching submitting photos to stock companies. However, I have some questions about releases. Model releases are self-evident, but property releases seem a bit more complicated.

What’s Your Priority?
I typically use my camera in automatic mode, but occasionally I step out of my comfort zone and move into some of the other modes. I really understand the full manual mode but, quite honestly, I don't get the whole aperture priority and shutter priority. I know what they are supposed to do and I sort of get when you are supposed to use them, but when I take pictures, I often switch between the two and I really don't see much difference. Is it me or the camera?

Tales Of Two Choices
While searching online for a mid-priced, 67mm circular polarizer for my Nikon D200, I came across this filter description that has me puzzled: "Used like and gives the same effect as [a] polarizer, but designed for cameras with beam-splitting metering." Is this filter a polarizer? How do I know if my D200 has beam-splitting metering, and if I use this particular lens with my D70 or something new later on, will this filter no longer work? Is this a concern for all circular polarizers, or is this model by Tiffen something special?

Bang For The Buck
About a year ago, you helped me decide on an SLR camera, and I love it. I've taken a short camera class only to learn there's so much more to learn. Now I want a versatile lens, so I can carry just one lens with me. I'll need a zoom (150mm to 300mm?) as I'm sure to be far away when I want to take pictures of tennis players and capture action shots. I know from friends that the lens can't be too long or you can't take it into sporting events, and I need a lens with stabilization. Also, I teach first-grade speakers of other languages, and I enjoy taking their pictures, too.

Get The (Focal) Point?
Q) I want to start shooting photos of local bands and some other bigger acts that come through my area on a regular basis. I'm new to the D-SLR game and still learning all the things I can do with my camera. So I'm looking for some advice on what settings to use while in this type of situation. Of course, it's low-light and fast-moving action, along with light changing all the time. I'm in the market to buy a new lens specifically for this task, but would love to also use it in the field for the nature photography I'm starting to enjoy. I'll have access to the sides of the stage and the front of the stage on the calm side of the barrier, so I'd think that my shooting distances could range from about six to 25 feet.

When New Tech Meets Old Tech
Q) A lot has been written about the amazing things that can be done with plug-ins. PCPhoto has given me a lot of great tips as I've been learning more and more about using layers in order to fine-tune my digital images. I've become fascinated by what I can do with filters when editing my images. So now I'm wondering about whether I even need any filters when I take my digital photographs.

Pick your approach In Windows XP, I have many subfolders defined for basic photo organization; however, I like to rearrange thumbnails in the folders as one would in a photo album. But I find that Windows often rearranges the thumbnails after I've spent a lot of time organizing them. I've tried turning off auto arrange, but it seems to happen anyway.

Q) I'm trying to figure out how the exposure compensation works on my digital SLR. It doesn't seem to affect the metering. Am I using it the right way, or is there a problem with my camera?

Step Up To A Larger Filter
Q) I'm about to purchase a 28-75mm lens for use with my digital SLR. It has a 67mm diameter lens; however, I have a 77mm circular polarizer that I would like to use with the new lens. I also plan to purchase a 67-77mm step-up adapter so that I can use these larger filters on the smaller lens. My question is, how will the quality of the image be affected by not using the exact size filter required, i.e., a 67mm polarizer on a 67mm lens?
