More pixels can capture more fine detail so you can crop away unwanted parts of the photo and still make a high-quality print. Consider this: If you crop away half of a megapixel photo, you'll still end up with a 6-megapixel image, which should have a lot of rich detail.
In general, if you're comparing two cameras with similar megapixel counts, the one with the larger sensor will generally take better photos. That's why some photographers pay a premium for digital SLRs with full-frame sensors. While the megapixel rating tells you how many pixels are in a photo, there is another important thing you sometimes need to know about your photo: the file size of an image that the camera produces. This directly affects how much storage space it takes up on your hard drive, its size as a file attachment in email, and how long it takes to traverse the Internet.
You might think of this as how "heavy" the file is, as if you were weighing photos on a scale. Alas, there's no direct way to correlate pixel size and file size. A megapixel photo might "weigh" less than a megabyte on your hard drive.
Or it might "weigh" as much as 6 megabytes. The file size depends on several factors, including the number of megapixels, the file format you're using such as JPEG or RAW , and the amount of file compression used to save the photo, which is sometimes referred to as the quality setting.
You can use a lower quality setting when saving a JPEG to significantly reduce the file size. Of course, if you try this, always save the smaller photo as a new file, so you don't damage your high-quality original. If you've ever noticed that the file size of a photo changed significantly when you saved it in a photo editing program, it's usually because the photo has been saved with a different quality level--and hence compression level--than it started with.

My 35mm reference in the chart is an average of 19MP. I arrived at this number after scanning many, many slides and negatives. Most people are not shooting Velvia or Agfa I found the information extremely helpful and was fully able to understand that this is meant to be an average.
There are always exceptions to the rule and I feel photography is about bending the limits of perception quite often, even through outside sources. Essentially many things are possible through diligence and hard work, then there are the rest of us. I am grateful to the time you spent on this for us. Best Wishes, Jason ". I wonder if there is a way to estimate the approximate "megapixel equivalence" of those early Leicas and Contaxes of the time when 35 gained wide acceptance.
Any thoughts on how to arrive at this? I believe its the opposite. I am, of course, disregarding all "consumer grade" cameras and film. First of all, many of the famous photographs from 40s, 50s, and 60s that we recognize today, were shot with a Speed Graphic or similar camera on 4x5 film.
I developed my film by hand and I have 20" x 30" prints on my wall with virtually no grain and detail that surpasses any DSLR I've seen, up to 16 megapixels. Personally, I've been waiting a long time for digital to catch up to film. It's now and I think its just beginning to happen.
I have read several of your very well articulated articles, thank you for devoting the time and energy to help many people out with these concepts. I am thinking and planning ahead for potential exhibitions and the relationship between ppi and viewing distance has been of particular interest. I was wondering if you had published an article or table of this somewhere?
Thanks Robert! A viewing distance chart is on my to do list. I think some people here are totally missing the point of your exercise!
How many times do you need to explain it for them? It's much appreciated and has helped me understand better thank you. Good chart, and you did a good job in the comments of explaining the caveats. I would add that some photo editors and printing utilities allow you to print a test strip before you print large or have it printed by a lab. For example, you can set the print size at 16x20 and the paper size at 4x6. The resulting 4x6 print will be a strip or patch at the scale of the 16x I do this regularly with Qimage and it saves a lot of paper and ink.
My suggestion is to add the standard photo paper size 2R, 4R, 8R, etc to the chart. Thank you! For those of us that use a camera non-professionally, this is a great rule-of-thumb guide, particularly if you might be in the market for older tech and need a simple comparison. And still, as of start of most of compact cameras, don't have this resolution. But probably most professional will have at the end of year I'm shooting a Canon 7D It will be fun to check back in a few years and see where this page is!
This does not hold true for high contrast "line art" type images lettering, logos, "graphic art", etc. In this case, vector formats are desired, and if it must be rasterized, then dpi is considered to be low and is recommended.
For an amateur photographer, this is really helpful in understanding what magazines editors mean with 'at least ppi' and what I need to do to deliver the requirement.
This is exactly what I've been looking for. Both the Apple Aperture people and the guys at the Photo Lab were convinced the math was long and complicated. Thanks ". All the other articles I've read confused me more. In fact I haven't found one yet that is as good as this article.
