For those who may be reading this and looking to buy digital SLR or digital point/shoot models. The higher end of each model DOES NOT only have 72 dpi typically the higher end models will be 180 or 300dpi. For example, Canon has 10D, 20D, 1D, 1DS, etc and they are all way above 72dpi, but when you get an entry level camera like a Rebel you get scaled down versions of the pro models, that is how you save money on them. Yes, it doesnt change the pixel count, but over all you still have a bigger image with the same amt of pixels due to not having to resize the resolution.
The pro models have options that most everyday users will never have a use for, such as a photo that can be printed the size of a door, or a strobe sync plug, or a custom function, etc.The pro models don't have onboard flashes either. For entry level SLR, you get a lot of bang for your buck and if you dont have the need to print images bigger than 13x19, then you really dont need a bigger, heavier option packed camera. For Canon the Rebel models are great and For Nikon the D50 and D70 are entry level models that are worthwhile. Olympus has the E-300 Evolt which is a newcomer and very nice as well. The Pentax ist is also a nice entry level camera. Most users will never outgrow these cameras.
A note on camera stores. Find your information online, or go to a pro level camera store, don't go to Wolf, Ritz, etc. A pro level store has great prices, the people who work there are pro photographers with lots of experience and they dont work on commission. You can try the camera out along with a variety of pro level lenses to go on the body to get better crisper clearer brighter images. Their prices are usually lower than Wolf etc. as well. If you research online forums and places like stevesdigicams.com you will find a wealth of info, try out how the camera feels in your hand a local store, then order online if you want to save money. B&H is a wonderful respectable online store. No tax either (unless you live in New York). Places like Ritz and Wolf and other privately owned consumer level camera stores have employees that are no different than you and I, they just went in and applied for a job, they give advice about stuff they have no idea about so they can make a commission, they are mostly uninformed and typically not photographers or maybe just starting out in photography and are not qualified to answer your questions. If you want to know if your local camera shop is a pro shop, its easy to tell. A pro shop will have pro lenses, ask for certain models (like a Canon 70-200 IS L lens, or a Canon 17-40 L lens, etc.), a pro shop will have tons of backdrops in stock, pro papers, and just about every gadget you never knew existed. It will not be arranged with lots of extra space for browsing, they will be overcrowded with supplies and usually have TONS of pro camera bags, they will have several carbon fiber tripods, etc. There is no feeling like walking into a place where you know you have landed in the right spot.
A pro level store will carry tons of point and shoots and let you try them all out before you pick, they will have every level of SLR as well, and all the lenses from consumer to pro. The advice and info they give you will help you pick the right model for your own needs, etc. These stores are not on every corner. For example, Dallas has 3 major contenders, Arlington Camera, Competitive Cameras, and Camera Warehouse in Carrolton (not positive on that name), and the one in Arlington is by far the best, has great selections, customer service etc. The one in Carrollton does not have as much stock on hand but is still a great store. Competitive Camera is downtown, and you couldnt beat me with a stick and get me to go there. You walk up to a desk, wait in line forever and they hand you a box....they have all the stuff, but its a warehouse environment, you need to know exactly what you want before you go, its not a place to try out stuff or get advice, etc. So use these as judgement of the right kind of store for you.
I am a professional photographer and have a lot of experience in the buying arena!.....after all, I am still a woman!
