Hi Everyone,
I have received many great (and constructive) remarks on my first entry here at DPChallenge. I thank you all. A handful of comments say I am slightly out of focus, about the same say nice clear focus. When I view this photo on my monitor at home, it is crystal clear. When I view it at work, it appears slightly blurred. Is this caused by the jpg compression? Or perhaps the size of file (67kb) I have read several posted recommendations to utilize the max size file (150kb)– How do I make the file larger to gain the benefit without exceeding the 640 x 480 rule? - The original file is 19 megs, Is any of this related to my blur?

General procedure (assuming you''re using Photoshop or equivalent) I use:
0) backup original imag capture to CD
1) crop and resample image to 640x480 (or 427) and save in PSD format.
2) adjust photo
3) flatten any layers and save in uncompressed TIFF format (or a new PSD file)
4) sharpen if necessary
5) use SAVE AS COPY command to save in JPEG format -- start with highest setting. Hide Photoshop and check file size. If >150kb go back to the TIFF file and repeat the SAVE AS COPY procedure lowering the JPEG quality setting progressively until you get a file small enough (usually a setting of 5-7).
6) when done, close the TIFF and discard changes (sharpening step). If there''s a problem with the JPEG, you are 1 step away from correcting it and re-saving the JPEG.
7) Back up all files.
That Nikon captures 19MB? Wow!

Here's some food for thought. Maybe you need glasses?
Seriously. I'm not being coy or sarcastic.
I found for closeup examination of photos a nice set of needlepoint glasses allows me to see the very fine edges of an image. I have a 19" monitor in my office set to 1024 x 768 and the edges aren't quite as clean on that monitor as my daughters 17" 800 x 600 monitor although the dot pitch is .25 on both. That extra bit of real estate may make the .25 dot pitch seem fuzzier as well..Can't say.
But...if you have a $4,000 camera with the quality of lenses you can put on that baby and photoshop there is nothing wrong with your capture equipment...it is definitely user error :-) |

If you're file is 19megs. then you're probably shooting in .tif format. If you have the software to process raw (.NEF) images you could reduce the file size to around 4megs. compressed or 7.5megs. uncompressed. Either way, the quality you're getting is far more than you should need for this site. GeneralE's post has a good workflow for your images. There are a couple things I'd like to add. You should be sure you're shooting in the proper color space. The D1x allows you to choose between a 2 color spaces. Most cameras use a variation of the sRGB color space and that would work, but you can choose Adobe RGB (1998) which would give a wider color gamut. Next, after you've loaded your picture into Photoshop the best way to adjust the size is to select the crop tool. In the palate at the top of the window you can choose the size of the crop. If you choose 8.889" x 6.667" and a resolution of 72 dpi, you will have an image that's 640 x 480 pixels in size and weighs in at 900k. Whatever part of your image is selected by the crop marquee will be that size (and with your native resolution you can crop pretty deep). Then you can go to the 'Save For Web' menu item. If you click on a triangle at the right side of the page near where you select file type and quality, you can select 'Optimize to file size' from a pull-down menu and enter 150k. You're file will be about that size, usually 50k. or so less.
On a different subject, if you're file is sharp at home and blured at work, and you're viewing the final output file (the 67k. one) on both monitors, then one isn't working right. I'm getting the same comments on my picture. One will say it's sharp, and the next one will say it needs more unsharp mask. What to do????

I'll tell ya what.. I have a camera that will shoot 640x480 photos and they are ready to go right out of the cam... I'll trade cameras with you and you will be set :)

Is this is a Photoshop only thing, or am I somehow missing the whole menu with the 'Optimize to file size' in Elements?

I just wanted to say thanks Things are looking much better on this end.
GeneralE you are brilliant thanks for the step by step help here.
Hokie, I have my glasses on.
Sheyingshi88, I have been able to maximize the file size just as you suggested.
Jmsetzler, I̢۪m still giving your offer some thought, (I̢۪ll let you know).
By the way, Thanks to your help here, you are all in trouble on this next challenge (;-D)->-<
