I did several 20x30 prints with D200 with very good\excellent results. These prints were as a birthday present. I asked my friends to look closely and tell me if the image quality was good. Everybody said - it is great, no one complained about sharpness. I still use D200, with good prime it can produce very sharp images. Colors from D200 are my favorite.


I still have my d200. It was my favorite digital camera. I even had a prism focus screen made for it that worked just like my old FM. Love that camera. It made beautiful prints

Yes, it is confusing and you are completely correct in saying dpi is NOT ppi and you need much higher dpi to deliver equivalent ppi. My Epson printer claims a resolution of 5760x1440 dpi, but does not specify equivalent ppi, so I did a little digging and found out that both Epson and Canon printers are good for somewhere around 240 to 280ppi and quality drops off significantly above this. Here's the reference from the well respected dpreview:

The bottom line is, however, that there is a definite physical limit to the number of ink squirts the printer can put on the paper, and it is not going to be anywhere near the same as the pixel resolution of our modern sensors. The result is that whereas the pixel peepers with their hi res, enormous monitors are going to be able to see a big difference between a shot from a 40 meg and a 16 meg sensor, especially when they crank up the magnification, the same difference is NOT going to be visible on an 8.5 x 11 print from your normal home printer!

Cat, I think it's the quality of the 8MP that's involved and it's not just the total number of megapixels. For example, suppose I took two images with the same 8MP camera body but with two different lens, the first a crappy lens and the second pro quality lens. Nobody would be surprised if the image with the pro lens was sharper than the one take with the crappy lens even though both images are the same 8MP. Depending on the subject, lighting, atmospheric condition etc those differences can be more or less noticeable.

Taking the situation that you posed, a 24MP body and a 12MP body, the 12MP body will capture less detail than the 24mp body. When the 12Mp image is reduced to 8MP, the details that were lost will not appear in the final image. When the 24MP image is reduced to 8MP, some of the details that are in the 24MP capture(but not in the 12 MP) will remain in the 8MP print. It's the amount of detail that is contained in the 8MP print. Just as in the case of a crappy lens against a pro lens, the amount of detail captured and sent to the printer may yield differences in sharpness.

I hope that made sense.

Only makes sense if whatever processor is selecting the bits to send to the printer is doing a better job selecting what bits to send with the 24 meg file than the 12 meg file. It would make sense then that the very best file to print, in terms of accuracy of detail, would be one whose pixel count exactly matches the ink dot count, so that EVERY pixel is represented in the print. That would remove the uncertainty inherent in the process.

Why?

If you have $100 in your pocket can you not spend $25 at checkout?


It does not matter whether you have $100 in your pocket or $1000 in your pocket if the item you purchase only costs $25! The printer can only put 8 megs of different spots on the paper. The processor has to decide which 8 megs of the 24 megs or 40 megs of pixels to send it, the rest of the pixels represented in that digital file will NOT appear on the paper. Only if you are going to make very large prints will you see the remaining information represented and will you be able to discern a difference.

Look, you are painting a wall, It takes 10 ounces of paint to cover it. It does not matter if you have a quart of paint, or a gallon of paint, the same 10 ounces of paint is going to cover the wall. You can use all your gallon of paint if you have a bigger wall, and if you try to cover a much bigger wall with the quart, you WILL see the difference!

But if I handed you two identical 8x11's, one taken with a 12 megapixel camera and one taken with a 24 megapixel camera, you would see the difference.


How is that possible if the maximum number of dots of ink that a printer can put on the photo paper is around 8 megs? It cannot possibly record more detail from 24meg pixels than it can from 12 meg pixels since in both cases it can only place 8 megs of ink spots on the paper?

1. It depends on whether both enlargements are from the same size area of the sensor....same cropping amount, or no cropping with either one
2. Depends on viewing distance, and your own visual acuity.


An 8.5 x 11 print ultimately depends on (8.5x300) x (11X300) maximum ink dots no matter what size file is fed into the printer.

I would love to solve this mystery I've heard for years. I have always been told that if you develop no larger than 8x11 that pixels don't matter. So, my question is this. If you develop a picture that's 8x11 using a 12 megapixel camera and another picture that's 24 megapixel will I be able to tell the difference? We must assume we are using cameras that are as like each other as possible. Let's not get into a ten year old camera and a modern camera conversation. Want to compare apple to apple as best possible. Thanks for your thoughts. Bryan

The maximum number of dots that can be printed on a piece of 8.5 x 11 photo paper, by a 300dpi printer, is 8,415,000. Even a 40 megapixel file will only be represented by those 8,415,000 dots of ink. So a 10 meg camera's output will be no less detailed than a 40 meg. Only when you get to much larger sizes will you be able to see a difference. I have very sharp detailed 8 x 10 prints from my original 2 meg Canon - my very first digital camera.

Wouldn't they be competitors?


Groomers are not photographers. They would be the perfect collaborators. They know all the people who pamper their pets, and make them beautiful so you can photograph them! I am sure that grooming shops are often asked by clients for referrals to someone to make a portrait of their pets. The mechanics of equipping a van for photography will be similar in some respects to setting up a mobile grooming shop. Even a fairly small van could be equipped with awnings and outdoor backdrops that could be set up outside the van quickly and stored quickly. Pet portrait clients will often want the dog photographed in their home environment - a favorite sofa or room to provide context, so it is important to have readily mobile equipment and lighting that can be moved outside of the van interior.

My suggestion is to tie in with a mobile pet grooming service.


Distribute your cards to all the pet groomers in your area. Visit them, and leave samples of your work.

I have searched pet photography topics on Ugly Hedgehog, and there are many. However, unless I missed it, I did not find anything on starting a mobile pet photography business. I’m thinking about using a bumper pulled trailer outfitted to take to various locations where the pets would come to me for seasonal portraits (think Christmas, Thanksgiving, Easter, etc.)

I have tons of camera and lighting equipment, and I have the ability to build custom sets and, but I would appreciate making contact with others who have built a mobile pet photography business. I have many ideas about making this successful, but I'd rather not have to re-invent the wheel, so to speak.

I show my dogs, and the dogshow people always want photos of their dogs. Your local kennel club would be a contact to make. Local dogshows would be a good place to visit and set up a booth. You can locate upcoming shows at http://www. infodog.com. Ad in the local papers also.

Regarding photography, I may say “whatchmacalik” a lot. It comes from my enormous ignorance. And I am always surprised when a photo comes out alright. Some crazy people even buy my photos due to my unique approach: “No, No, Ma’am, the photo comes with the frame. You can’t just buy the frame.”
Anyway, I, as you can imagine or not, I cannot seem to get the hang of using the eyehole thingy at the back top of my camera.
Anyhow, every photographer worth his or her salt prefers the eyehole thing. While it seems like a great idea, I keep having to change the focus. It is uncomfortable with my glasses on but I lose my subject if I remove my glasses.
I know asking this question is ludicrous given the sophistication of you all (which is totally impressive even if most of the time I am Mystified by the lingo). I embarrassed to ask for help, but my little camera insists I get help (I hope it is regarding the camera stuff and not the other daily challenges I face).
Thanks. And my poor subjects thank you.

First, although I’ve loved “taking pictures” for years, I still consider myself a rookie. I loved my Nikon D50 (we went everywhere together) but recently I got a Nikon D500 camera body.
What I’d like to know is what you would recommend as a good all-round versatile lens. I like street photography, landscapes, old buildings/ruins, dogs (I go sheepdog trials whenever I can), horses - action shots in general - not too much into portrait photography. Also, at the sheepdog trials, the action is usually far away. What’s a decent lens for that sort of situation?

Thanks in advance.

The one lens that would cover most of the situations you cite and still be compact and lightweight, is the 18 - 200. I used it for years and it covered 90% of everything. It gives you the equivalent of 27 - 300mm, and is quick focusing and sharp.

I have one of those circular translucent WB filter. Can someone tell me the exact way to use it.


Why would anyone go to the trouble of screwing on an attachment to the lens, and then taking it off again, and stowing it somewhere, when aiming the camera at a sheet of typing paper does the same thing? My answer for your question is "Put it in a drawer and forget it."

Some suggestions, please, a wide angle lens for my Nikon D7000 - I’m a casual photographer, it’d be great if it were an all around lens........


Nikon 18-200 is a nice compact sharp and versatile lens. When I had Nikons, I just about never took it off the camera. 18-200 covers about 90% of situations.

All that matters is that the buyer THINKS the camera will take better photographs. Don't we all do that when we buy a camera. We spend a lot of money thinking the particular camera will take better photos than another equally priced camera.


No Dennis, we all don't. Not everyone labors under that delusion.er bases. Most photographers are aware that almost ANY modern interchangeable lens camera will deliver excellent images if used properly. Choices are made on other bases such as weight, size, ease of use, and specific features and handling advantages.
