Your comment caused me to look at the specs for a 50-inch 4K UHD TV. It really isn't important how big the TV is when measured in "inches" or "centimeters", etc. What you need to know is the pixel resolution. The Samsung site and the manual quotes 2160p, where this advertised 2160-pixels refers to the vertical side, aka the short side, of the image.

So what does this information mean to the digital photographer?

a) It means your uncropped 24MP image (6000x4000p) is almost twice as high vertically as can fit on this 50-inch 4K Ultra High Definition (UHD) TV.

b) It means if you resize your 24MP image to match the short-size pixel resolution, your image would be 3240x2160px at a 3:2 aspect ratio.

c) This particular Samsung appears to be a 16:9 aspect, where if you resize your image to perfectly fit the pixel resolution of the screen, you'd have a 3840x2160 image.

So the take away is that your run-of-the-mill 24MP digital image doesn't have to be resampled for full-screen display on a 50-inch 4K UHD television. In fact, this $329 TV at Best Buy doesn't have the pixel resolution needed to show the original 24MP image at the full 100% resolution of the image file / camera sensor.

To understand more about pixel resolution and digital images, please refer to the presentation at this link: Recommended resizing parameters for digital images

Trying to fit today's digital images to a modern digital TV can be difficult at best. Most digital TV's are 16:9 aspect ratio. Most photographers shoot in 3:2 aspect ratio. As you can see these two ratios do not match. You have heard that TV adds 10 pounds to a person's "look". The aspect ratio is what causes this, even if so slightly. When I post photos for our TV station, I crop them to 16:9 to avoid cutting off someone's head or worse.

The camera’s image size and dimensions are determined by the sensor. The most common aspect ratio being 3x2. An image must then be cropped to to achieve a different ratio ( 4x5, square, etc..) for printing. Some Canons will display a grid in the viewfinder to help you pre-visualize the shot in a different ratio, but the uncropped image will still be 3x2 aspect. If you want to print 8x10 you’ll still have to crop to 8x10.


Well explained.

Here's a suggestion, Go one way or the other, either all full frame body and lenses or crop body and lenses. That way you won't have to worry about these issues. Sometimes, making life simple is all it takes to make us happy. 😊

I think the brighter sun being metered from behind the subject would make the subject darker, so wouldn't one increase exposure to compensate? I see you have the RP so you probably do what I do and let the exposure simulation tell me which is the right direction ...Meter? I don't need no stinkin' meter!


You are correct. It's too early in the morning. I like the Mirrorless Cameras just for this type of setting. You can see exactly what you are getting through the EVF before you take the photo. I still use my 5D Mark IV for sports and such and when I do I miss the EVF feature of the RP.

I would shoot in Manual Mode and adjust settings so they are under exposed to account for the sun.

I use the Canon 470 EX II for all my flash needs. You can get the newer AI version, but it's not necessary. If you can't bounce flash, (outdoors or high ceilings) the AI will be of no use.
The EF 28-135 & EF-S 18-135 3.5 - 5.6 would be a good all around lens to consider for the 80D

I've replaced my rubber zoom ring on my 24-70. Replacements shouldn't be hard to find.

I have a Canon EOS 7D, and I suddenly realized that I will shortly be out of 4 digit numbers for the camera to assign. It started at 2000 and it may have already over-written I'm not sure. Can someone tell me what the rules are for the numbering or where to go look?


The camera will reset to 0001 when it gets to 9,999. I carry 2 cameras and run into duplicate file numbering issues all the time. Occasionally I will reset a camera back to 0001 to avoid duplicate file numbers. Another idea, with Canon, you can use custom file names.

I'm familiar with the Buy/sell/trade portion of the forum but I'm posting here that I'm wanting a 70-200mm f2.8 lens to use on my Canon 80D DSLR. Mainly I'm curious what the forum members think as they compare the Sigma, Tamron and Canon lenses? How do they compare in image quality before I start researching prices? I will use almost exclusively to shoot college soccer games on the sideline. Currently I'm using the Canon 70-200mm f4L lens and am thinking the f2.8 might be better. Because I'll be shooting with a high shutter speed around 1000 or 1200 I don't feel I really need image stabilization.

I have both 70-200 f/4 L IS and 70-200 f/2.8 L IS. I shoot college soccer on the sidelines as well. Both lenses do very well for sports, unless it starts getting dark, then the f/2.8 is my preference. Also I use a 2x extender. With that extender you lose 2 stops so the f/2.8 lens works better because i still have f/5.6 if needed. I like the Image Stabilization on both lenses and would not buy a lens without it.

I am trying to learning Affinty Photo.
Attached are 3 recent photos. I don't think they are bad, just not as good as I wish they were.
Couldn't figure out how to send raw files so here are some JPEGs with no processing, straight out of the camera.
I'm here to learn so let me have it!


I looked at the football photo, here's my suggestions,
1. you are using a 18-200 3.5-6.3 lens at aperture priority. My experience with a variable aperture lens, the aperture needs to change as you zoom, (you really don't have that much control over aperture) rather shoot shutter priority and let the aperture move.
2. You are using center weighted metering, which means the light meter is only looking at what is in the center of the image, making your photo appear darker than it should (red jersery). Use evaluative metering, this allows the light meter to evaluate the entire image giving you a brighter image, hopefully.
3. You were outdoors at 4pm, the aperture should have been somewhere around f/11 to f/16 this would have given you more DOF and everybody would have been in focus.
4. I sharpen every photo I take in post editing with batch processing and I shoot in Standard picture style with sharpen up 2 notches.

So the HD finally stopped on my 7 year-old Lenovo i5 desktop. Became very slow and then would not reboot, and got a message that "no OS found". This happened before on my work computers. So I took it to Staples and we decided on a new 2TB drive, 240G HP SSD for boot and programs, and I ordered 16g Ram from Best Buy to replace the original 8g. Should be faster than before. Also Staples will work to transfer files to new HD, esp Documents and Photos. Surprised at the amount of dust and lint inside the case and on the motherboard, even though I always wipe off the fan vents of dust. Anything I need to do differently now that I will have a separate SSD??

The SSD Drive will allow you to boot up very fast. Not sure why you went with 2 HD's though, One 500 GB SSD would have been sufficient and then store photos on a HD offsite.

Why not try shutter priority, with the speed you need, and the ISO set so you get the f-stop you want?


I agree, why not try shutter priority? With that lens, I would not shoot slower than 1/200 anyway.

I have updated mine and have not seen the issue. there is a setting you can change that will change the way you see the photo taken through the viewfinder to smooth.

I am shooting community college soccer daytime pics using a Canon 80D with the EF 70-200mm f/4L IS USM lens. I'm confused which focus setting I should use on the Canon 80D. Thanks for suggestions.


This photo was shot with my Canon 5D III, 70-200 f/2.8 IS L lens at Shutter Priority, Shutter Speed, 1/1000, Aperture F/6.3, ISO 2500, zoom 400mm (with a 2x Extender) Using single point focus, AI SERVO and Back button focus and high speed continuous shooting. At 7:00 pm on a sunny, early evening.
