Upgraded from my rebel T7 to the 90 D because I wanted something more professional within my budget. Photos are coming out with what seems to me to be more noise than the photos I was getting with a T7 I’m wondering if it’s something I’m doing wrong or if my expectations are simply too high
ive been holding my camera Close to my body and gently squeezing shutter
photo info:
iso:100 ap:14 tv:1/60

The “ 1/FL Rule “ is a guide for setting a minimum shutter speed, not your actual shutter speed. The rule applies to full frame image sensors. When using a camera with an APS-C sensor I would advise using 1/(2*FL). But, because of the high resolution sensor in the 90D I recommend using a minimum shutter speed of 1/(4*FL).
There is [no] rule that says all photos must be captured using ISO 100. With a wide angle lens, the Depth of Field can easily extend from a few feet away out to infinity using f/5.6.
Again, I recommend using P mode and observing the camera settings that [the] camera chooses. With your 18-55mm lens, try to use a minimum shutter speed between 1/400 and 1/1600, depending upon how bright the outdoor scene might be.

There is definitely a learning curve with every new camera 🙂 I have been shooting sports with Canon 1DX series bodies for years and I just bought a tiny Canon M6 Mark II for easy carry on for pleasure flights and I have had to relearn a few things with it.
Using the rule of thumb that the shutter speed should be at least as fast as the reciprocal of the focal length, 1/60 sounds find for 18mm but keep in mind that 18mm with the APS C sensor is equivalent to nearly 30mm in terms of that rule of thumb so 1/60 isn't as conservative as it sounds. And the rule of thumb is a little less useful as you start getting into very slow shutter speeds like 1/60 where it is pretty easy to create motion blur from camera shake, especially when using a 32 MP sensor.
With the lens set for 18mm focal length, if you use a f5.6 aperture setting and focus on a point 20 feet away then everything from about 10 feet from you to infinity will be within critical focus. This avoids being so far beyond the camera's DLA and will also result in a much faster shutter speed for the same exposure conditions avoiding any chance of camera shake causing blur.
And congratulations on having a VERY important job. The first year I was in my PhD program, I was stuck in a malfunctioning elevator early on a Friday evening. Thanks to the fast response of an elevator service person, I was out of the elevator in under two hours 🙂
