tim_knight Posted April 20, 2006 Share Posted April 20, 2006 I am seeing a thin white ghosting around the bird after cropping it. I have the Nikon D50 with the 18-70mm kit lens. Please tell me what I am doing wrong. Here are the photo details.No flash, ISO 400, resol. 1504x1000, F/L 70mm, exp/ 1/800th sec, apt f/4.5, metering mode-matrix, using Manual Mode. Please tell me what I am doing wrong. I am also using a mono pole. Thank all of you for your responses. Link to comment Share on other sites More sharing options...
don_cooper Posted April 20, 2006 Share Posted April 20, 2006 Pretty hard to tell without you posting the photo. Sounds like you might you be shooting in lowrez JPG mode. Link to comment Share on other sites More sharing options...

elf Posted April 20, 2006 Share Posted April 20, 2006 Can't tell without seeing a pic. How little of the image is bird? Link to comment Share on other sites More sharing options...
ifeito Posted April 20, 2006 Share Posted April 20, 2006 C'mon Tim, you can do it! Post the image! =) Link to comment Share on other sites More sharing options...
pjmeade Posted April 21, 2006 Share Posted April 21, 2006 Just a guess without seeing an image, have you added lots of sharpening? Than can sometimes give a halo. Link to comment Share on other sites More sharing options...
jimitoucan Posted April 21, 2006 Share Posted April 21, 2006 Camera shake? yep, even at 1/800 sec. if your technique is off. won't show up until you look closely. Try sturdy tripod. Link to comment Share on other sites More sharing options...
dave_terry1 Posted April 21, 2006 Share Posted April 21, 2006 Is this a hummingbird? With no flash, you'd get some ghosting of the wings even at 1/ 800th. Link to comment Share on other sites More sharing options...
tim_knight Posted April 21, 2006 Author Share Posted April 21, 2006 Bird feeder is ~9ft from the window I shoot through. Even with 70mm lens the bird is small in the full picture. I guess I am cropping 10% of the picture to get the size of the bird I want. I used a light digitalization adjustment to sharpen the picture. I do drink a lot of coffee at night (I work 3rd shift)and take a most of my pictures in the morning after getting home, and did not use the flash. Sounds like all of you had good possible reasons for the ghosting around the birds. I will try some of the suggestions and see if it corrects the problem.

greg s Posted April 21, 2006 Share Posted April 21, 2006 "I guess I am cropping 10% of the picture" If by that you mean you are cropping out 90% of the pixels and using the remaining 10%, then I'm not too surprised you would see some type of edge artifact... expecially if 'in camera' sharpening happens to be turned on.

craig_shearman1 Posted April 21, 2006 Share Posted April 21, 2006 If the resolution is at 1504x1000, that's only 1.5 megapixels out of a 6 megapixel camera. Since you say you're on "fine jpg" I assume you mean that you've cropped it down to 1504x1000 from the original 2000x3000 or so that the camera shoots. That's like using about one-fourth of a negative, so it's going to make your image look a lot worse. I have a similar setup for birds and use a 300mm or my 500mm to get close at maybe 10-15 feet max. A 70mm isn't anywhere near what you need for this type of photography. The other issue is that you said you're shooting through a window. That could explain the ghosting -- you're shooting through at least one layer of non-optical window glass, possibly two or even three if you have modern "thermal pane" windows with an air space between the sheets of glass. And even if you're windexed the window for the sake of photography, it still isn't clean to the point that a camera lens would be clean. I think that's the most likely source of ghosting.

tim_knight Posted April 21, 2006 Author Share Posted April 21, 2006 I know I need more zoom, but right now I have the Nikon 50mm, f/1.8 on back order and will need to save more money for my next purchase. What do you recommend for $500 to $600 dollars. It also needs to work as a sport lens for indoor volleyball and basketball. Link to comment Share on other sites More sharing options...
kelton Posted April 21, 2006 Share Posted April 21, 2006 Tim, That 50mm 1.8 will work for basketball if you can manage to get behind the goal and have somewhat decent light. A better choice for both sports would be an 80mm 1.4 or better, unfortunately, neither of these would be good for wildlife photography in my opinion. Unless, of course, you are very sneaky.

elf Posted April 21, 2006 Share Posted April 21, 2006 I've got a 70-200 f 2.8 autofocus for a Nikon that I'll never use having switched to Canon. It's for sale. elf@cape.com my 75-300 on my Canon 10D with 1.6 multiplier gets goldfinches at 4 feet so they fill about a third of the viewfinder, through double window glass on a tripod.

tim_knight Posted April 22, 2006 Author Share Posted April 22, 2006 Emily, Goldfinchs and Purple finches are what I have feeding here in South Dakota. The Goldfinches are about 85% in full color. How are they where you live? Link to comment Share on other sites More sharing options...
elf Posted April 22, 2006 Share Posted April 22, 2006 Well, they've pretty much abandoned the feeder in the interest of nesting, but once in a while one comes by and they're a whole lot golder than they were in the winter. I'll try attaching my image of the winter one.<div></div> Link to comment Share on other sites More sharing options...
greg s Posted April 23, 2006 Share Posted April 23, 2006 "What do you recommend for $500 to $600 dollars." If you are willing to buy used on auction, the Nikon 300mm f/4 AF can be found in the $400 to $500 range. Very sharp, and you can use a Kenko 1.4x teleconvertor. One of the best deals out there. -Greg- Link to comment Share on other sites More sharing options...
elf Posted April 23, 2006 Share Posted April 23, 2006 It depends on what kind of sports, too. F 4 is too slow for most sports even at ISO 3200. That's why I bought the f2.8, which is marginal. When I shot basketball for the paper we pushed the Ilford 400 to 6400 in processing. It was only for newsprint, after all. Link to comment Share on other sites More sharing options...
greg s Posted April 23, 2006 Share Posted April 23, 2006 If it needs to be a good lens for volleyball as well as birds... I'd get one for each. Link to comment Share on other sites More sharing options...
