Thanks for your replay. I have always enjoyed photography. When I began my marketing company in 2009, my main job function was to help advertisers improve their sales, and not take pictures. One client was a small fast food chain which also had one high end sit-down seafood restaurant. Because there was a need, I picked up the food photography myself, and it was acceptable for the needs of this client.
The food photography needed was for use on their websites, for eblasts, and for collateral printing. Our goal for all of our food advertising has been to make the food appear most appetizing to the point that someone wants to eat the food. Focus has to be sharp. We like brightly lighted, and I use the best light situation which almost always includes portable, florescent studio lighting which I take to the shoot site which is always near where the food is prepared. For printed collateral material (posters, counter cards, table cards, banners) we use 300 dpi. Even though the internet requires less than that, we always start it high. If someone clicks on the photo, then we can't have it go grainy.
I have been using the D300S for several years now, and learn something about using the manual settings every shoot. If I am shooting food which doesn't move, then I make many shots using different settings. Then I select the one that looks the most natural.
Does that answer what you were asking? I will look for your reply, and thanks for your interest.

Yes, that answers it well enough. I don't think you'll have any trouble photographing food that way for the Internet, menus, news articles, cookbooks, counter cards, table cards, or even posters and banners.
Here are some dirty little secrets that the camera industry does not want you to know:
Virtually any modern dSLR or mirrorless interchangeable lens camera with 12 MP or more is up to all those tasks. Anything more is just bragging rights. There will be some here who dispute that, because they have been brainwashed into thinking that pixel-peeping matters, but hear me out.
All you need for those uses is 3000x2000 to 4000x3000 pixels (6 to 12 MP). Higher resolution is nice to have for cropping, but once you get into that range, you can scale the image via interpolation with On1 Resize or even Photoshop's new option, to make prints up to billboard size. Viewed at the diagonal dimension of the print or a greater distance, you won't see any jaggies or other problems. The eye can't resolve more detail than that!
"300 dpi" is a *scanner driver* setting referring to how many samples per inch came from a print or piece of film. As such, it was (is) used to tell a page layout program how to scale the image when placing it on a layout. OR, "300 dpi" is a *printer resolution* referring to how many dots per inch are laid on paper (300 dpi is ridiculously LOW... like the original Apple Laserwriter or HP Laserjet). Both of those contexts primarily come from the graphic arts (CMYK++ litho or gravure world). Both of these uses for the resolution header value in a file are over three decades old!
Still, your use of "300 dpi" probably is referring to the file resolution header value in the EXIF table of a JPEG file or TIFF file. That is now a *meaningless* value in photography UNLESS you also specify the actual reproduction size, as in 300 *PPI* at 8x10 inches. That would be 2400x3000 pixels, which is what really matters, NOT the resolution header value! The smart thing to do is to think of resolution as the total number of horizontal pixels times the total number of vertical pixels coming from the camera.
The concept of PPI is very different from dpi. What it essentially refers to is, "How many pixels from the camera sensor are spread over every linear inch of output?" If you have 240, that's what is sometimes called "extinction resolution," if you are looking at an 8x10 inch print from about 13 inches. What this means is that at that threshold, the vast majority of humans cannot see the pixels, and neither can they perceive any additional detail when the resolution is raised to a higher value. Having more pixels to work with is welcome, but most often not a requirement (other than some mis-guided editor's rule!).
From that point, what matters isn't megapixel count, but all of the other features that make a camera useful, and all of the other ingredients that go into photography, such as lighting, composition, contrast, color, line, form, moment, styling, square horizon lines, etc. ad nauseam.
If you don't like your old D300s, trade it in on a newer body. You don't necessarily have to have a D810... A used D610 or D800 would be plenty for the task, as would the 24MP D7100 and D7200 models. But unless you're going to be doing a LOT of work, I wouldn't overspend.
I would feel comfortable doing food photography with what I have... It's Micro 4/3, a 16.05 MP Lumix GH4 with pro grade lenses. Here's a file I made yesterday. It is cropped slightly and resized from the original to make a 40x30 inch print at 240 PPI input to the printer driver. Viewed from 50 inches, the diagonal of the print, it is fine. Download and examine it at will, including the EXIF table. I made this from a raw file in Lightroom, using Photoshop to resize a TIFF intermediate and sharpen it. I'll make the final print from the 16-bit TIFF, converting it from ProPhoto RGB color space by printing it on an Epson P-series. This is an 8-bit JPEG in sRGB.
