some work and hobby shoot trips, my result of a 4-hour extensive survey of the entire Metro Manila area has provided me enough intelligence (due to my ex-military background) to pick one most strategically located for the shoot - Best Western Hotel La Corona Manila. Centrally located close to the Manila bay, its pretty close to the old walled city, Chinatown and even the biggest shopping mall in Manila!
I hope having fun in writing has proved usefully fun to you too! 
OK. OK. The wait is on as your license is being reviewed and approved with the stock vendors. Now what? Wait for two weeks with our hands in the pocket? No Sir! While waiting, I would strongly recommend spending another 15 minutes to evaluate the possibility of setting up your very own photo stock online shop front!
For those who just managed to locate this blog, welcome to the one and only blog at the date of writing covering what the Nikon D90 is all about in greatest of detail, while helping every readers overcome the barriers of using the sophisticated camera as their first DSLR. You are advised to read from the first article as they are all time-chronologically written from ground zero. I started this blog after my purchase of the Nikon D90 in mid December 2008. So you are not too late if you are here for the first time.
In the MTF chart of this website, the horizontal axis is in millimeters and shows the distance from the center of the image toward the edges, and contrast value (highest value is 1) is shown in the vertical axis, with fixed spatial frequencies of 10 lines/mm and 30 lines/mm.
The MTF chart for each lens is based on the value at the maximum aperture of the lens; the red line shows the spatial frequency of 10 lines/mm and the blue line, 30 lines/mm.
In the off-axis field, contrast reproducibility of the lens for sagittal direction and meridional direction varies with astigmatic affection. The path of 10 lines/mm indicates the contrast reproducibility of the lens (the higher and straighter is better). The higher and straighter the 30 lines/mm-path is, the higher the resolution of the lens.
Note that the lens performance can not be measured only with MTF chart. Softening or blurring of color also governs measurement.
If you enjoy photography, a good logical step is to try and make money from your hobby. Then you can spend more time doing what you enjoy. Selling your photographs takes time and dedication, but it is possible. Lots of people do it, and you can too. Almost every professional photographer started out in some other field: Elliott Porter was a doctor, Ansel Adams was a pianist, Galen Rowell was a mechanic, Bob Krist was an actor. I am still a Business IT Advisor but you never know. If these people can start from nowhere and sell their work, so can you.
The nice part about selling photography is that anyone can do it -- you're not dependent upon physical ability, age, or background. It's more about art and energy. The photographic market is so open that every photographer and publisher I've met is pleased to give ideas and suggestions.
Swamped with work for the last two weeks! But hey, it's also a good time for me to stop thinking and start shooting! As you can see, my collection of shoot is growing steadily but surely. After all, its about the pleasure of shoot that gets me excited, and not so much of the technicalities.
Burning question - what is the biggest print size we can get out of our Nikon D90's 12.3 MP images? To calculate (in inches) the largest photo-quality print you can make from a digital file, using its native resolution, meaning no interpolation, divide the vertical and horizontal pixel counts by 240. If you are making images for commercial publication or other critical applications, or if you want exhibition-quality prints from commercial printers, divide the pixel counts by 300.
Let’s take an image from the Nikon D90 as an example. It makes a high quality jpeg image at 4288 x 2848 pixels. Using the formula above, that would generate a native print size of 17.8″ x 11.8″ at 240 DPI. Now remember, this assumes you haven’t "pumped" up the image in Photoshop.
The next step in the formula is to take this print size and multiply it by 25%. That is the largest amount of image interpolation the picture can stand and still maintain reasonable photo quality - in my opinion.
In this competitive and stifling lens manufacturing market, its a consumer market out there, with more-for-less slogan broadcasted from every camera retailers around us. This brings me to review some of the more promising lens manufacturers that seek to convince me of their better value lens.
I am sure by now, all of you are quite conversant with the Nikon D90's post "Image Overlay" capability but its more of a post processing work you are doing here. If you really want, the fact is that you can do it on-the-fly with the Nikon D90's Multiple Exposure feature (in shooting menu)! Turn it on and shoot up to 3 images before the camera auto-layered them into one image for you. Talk about creative possibility here...another cool feature I discover today.
Never have I seen such a wide range of Nikon lenses on an online shop so competitively priced - HK Supplies, that I am making a point to visit it in March 2009.
Attaching this $10 adapter kit on the Nikon D90, my 50mm F/1.8 lens is instantly transformed into an outstanding macro lens! Check the top image out for result!
