Low RPM/33mph Vibration/pulsing
Cayenne has done stints between 110 and 116 mph quite a few times without any noticeable NVH issues. Mine was actually installed at the dealership while I was having some other stuff done, so maybe that's the secret as they have the special alignme T tool to get it just right. The tool is used to align the center support bearing, and that's one problem area you're eliminating by going with 1-piece shaft. 300 tool, and no way to use it even if you have it. The folks at your dealership must've done a fine job regardless. Note that Pete's aluminum driveshaft looks bigger around, and would thus be stiffer and lighter than a comparable one-piece steel driveshaft. And practically speaking, it's been tested to speeds few are going to regularly exceed. It's probably also likely to last the life of the car. But at the age/value of our vehicles, a replacement factory shaft isn't a terrible deal if it lasts 50 or 100k miles. Either could make sense depending on your objectives. Sounds plausible to me.
Running a large pet photo shoot can be a lot of fun for all participants but you need to plan it well in advance and be completely ready for it when it starts. You can pick a place such as a side room in a school, church, business, or similar location. Sometimes, to get publicity, you can do one at a flea market. If you do a flea market, it's much different than a studio. At a flea market, it's more difficult. You are better off just having a basic system and doing a few shots for a modest price. Then, hand out cards and show some samples of what you can do in a studio. I have a lot of fun props that I can use but I don't take them all to large photo shoots. I might take a few. If you do a large photo shoot, keep some things simple, such as the camera and light settings.
You will have enough on your hands dealing with the subject. A bad background can ruin a picture. Professional photographers go to great lengths to set up backgrounds for their photos, so they usually have a number of backgrounds in their studio. In addition, they may also have a number of colored lights, or 聯gels聰, to color the background in a way that suits the subject. If you dont have a background, you can effectively use a common sheet if you mount it in such a way that it shows no wrinkles. One simple way to do this is to pin a sheet to a wall in a home. You can even use a blank white wall if you wish. To make the subject stand out from the background you need to have good contrast. For example, black or dark blue is very nice for light colored or medium colored pets. Black dogs and cats, however, are best put in front of a lighter background. Backgrounds are easy and cheap. In the beginning I used old sheets, stretched tight with small clamps.
Make a little stand about 8 feet high ( use a king size sheet ) It's good to have several. A grey or black one is also good. I also use blue quite often. When you get more money, get another flash unit to light up the background. You put it way down low and aim it up. Most pros use a background light as well. The background light is set off to the side, below, or above, and aimed at the background. By setting the background light carefully, you can put a spot of light just behind the subject. This helps enhance the contrast ratio and offsets the subject from the background. If you use a neutral background, such as grey, you can put colored 聯gels聰, or transparent colored plastic, over the background light. This enables you to put just about any color on the background. To avoid shadow on the background when using a flash, either have a good background light to offset the main lights, or have the main lights up quite high. That way the shadow is short and out of the picture. Also, keep the subject about 3 feet away from the background.
