I'm revisiting Bryan Peterson's classic Understanding Exposure, and it reminded me how often he shoots at f/11-22. I obviously can't ask him why diffraction does not seem to be a problem for him, so I am asking here. Is diffraction at small apertures overblown as an issue? Is it more of a problem under certain conditions and less so under other conditions? A confused mind wants clarification.

Thanks,

Ben


Print size and viewing distance and human eyesight limitations will always be the main factors regarding diffraction. Diffraction is always there. If you are looking at an 8x10 at arms length you will clearly see the difference between images taken at F8 and F22. However if you look at a print enlarged to 40x60 or bigger even F22 will look pretty sharp. There are other concerns like subject matter, image contrast etc.

I don't work actively to promote my skills as a photographer, but I would like to remain active and excited about taking pictures. Lately, I have been unable to come up with things to take pictures of. I recently went to the local aquarium thinking that would be exciting, however, all my photos turned out crappy. Poor lighting/ack of lighting plus those critters don't sit still for the shot-made for a waste of time and money. What can you guys suggest i.e. places to go, things to shoot, etc. that could get me really excited about taking pictures. Seems I am lacking in the area of focusing. I recently took some Halloween photos, which I thought the focus was spot on, only to have soft pictures.
Any suggestions on my request for help would be appreciated. Thanks

Pay more attention to your opportunities than your obstacles. When I find myself in a rut I just take my camera and go somewhere I've been to before and instead of looking for photo opps, I will sit quietly and take it all in with all of my senses - eventually image opps will reveal themselves. This may be best described as Contemplative Photography, which is easily searchable in google.

The NEF output for most of my images from the D850 is at least 50meg
The NEF outuput for most of my images from the D5 is around 25meg.

If the D5 is a better camera and far more expensive than the D850, why is the NEF output resolution apparently so much higher on the D850 than it is on the D5? Is there a major difference in the pixel size? Thank you.


Image size in pixels - which is what you really should be comparing - on the D850 is 8,256 x 5,504 pixels, while the D5 is 5568 × 3712 pixels - so there is most definitely a difference in resolution and the corresponding file sizes. For a fair and a more informative comparison, downsample a D850 image to the same size as the D5 - then compare and tell us what you discover.

Spoiler: You probably won't be able to tell them apart.

Consider the D5 analogous to a McClaren 720S and the D850 is a Ford Expedition. Both will get you from point A to point B, but the McClaren with its 20 ft³ storage volume will only move at most 2 people and fraction of what can be moved in an Expedition which has 104.6 ft³ storage with the seats down.

What would a carpenter from bygone days think about having power tools? or even more a sawmiller cutting siding and sheathing? We can give example following example of where technology has made life easier for folks in all walks of life.


My other hobby is cabinetmaking. I am fluent in both power tools and hand tools. They both are optimal at certain things and just ok at others. But very little returns the feeling of using a well-tuned quality hand plane, a wood chisel with a mirror polish on the cutting side, or the precision of marking and cutting dovetails by hand. In similar fashion, there's a lot to be said for Whiteside router bits, Timberwolf bandsaw blades, Forrest circular saw blades, and nearly every tool offered in the Festool catalog. The keys to success are to buy quality tools, and know how to pick the right tool for the job.

I’m new to the forum… thanks for including me.

I’m looking for recommendations regarding quality lightweight tripods. I’m mainly a landscape guy, but I’m interested in upping my wildlife skills. I shoot a Canon 7D Mark ll, with a current heaviest lens being a Tamron 100-400.

Specifically, I’m interested in opinions about tripod construction (carbon fiber, aluminum, or ???), name brand opinions, and cost expectations. I’m willing to spend money, but not needlessly throw it away. Please tell me the “why” behind your opinions.

I’m about 6 feet tall, so I would be looking for a tripod that can reasonably accommodate that height.

Any help you can provide would be greatly appreciated. Admin, if I’m in the wrong segment of the group, feel free to move the post.

You need a solid, carbon tripod. Light weight is not what you are looking for - most tend to be light but not all that stable. Even the expensive ones.

The EOS R5 changed how we think about mirrorless cameras, how we think about photography, how we think about life. The others, not so much.

But honestly, what are you asking? Canon has delivered mirrorless technology that leverages their change to EOS technology in October 1987, an all-electronic solution that continues to deliver benefits to Canon owners in October 2023. Contrast that to Nikon, a company that dithered on electronics and the basics of Auto Focus, where long-time owners find their long-time lenses are not fully-upward compatible with mirrorless cameras.

But honestly, what are you asking? Mirrorless technology is superior, especially the newest mirrorless lens designs, from every one of all the various market competitors. Some are clearly better at automated tracking of moving subjects, but this is a niche need for certain working pros. The rest of us couldn't / wouldn't know the difference.

But honestly, what are you asking? Did any of your current digital cameras turn to dust recently, or similarly stop delivering already superior images? Did your money start burning a hole in your wallet?

The single biggest difference: you mount a lens and turn right (clockwise) when working with Canon, clearly the right way to mount a lens. Everything else is just a difference mix of technology options. Do you want IBIS? How many megapixels? Full-frame vs cropped? What card format? One or two cards? etc, etc.

R5 as good as it is, was not the first outstanding mirrorless camera - Olympus and Sony did it first in M4/3, full frame and DX formats. In Sony's case, a full 6 years before Canon's R5. Just to put things into perspective. But the Sony lens support has taken a while.

Why does it matter? If you are a halfway decent photographer you will make good use of whatever you have.

Hello Gentle People:
I want to get a couple of my photos printed on a 24 x 32 canvas print. What is the best site for getting this done. Does any shop work directly with a RAW file or do you always have to convert to JPG?

Thanks
Photolearner01


If the print is big enough and the viewer is far away enough, more resolution that the eye can resolve is a waste. Of course there will be the pixel peeper bunch that insist on looking at a 40"x60" from a 12" distance with a magnifying glass and they will be disappointed at anything less that 1200 ppi. However a smaller print viewed at 12"-15" will need as much image resolution as possible to look sharp, even higher than 600 ppi.

Hi Hogs,

I am about to begin the second revision of my landscape photography book by Focal Press.? Exposure and metering are important skills to master. Over 40 years of photographing close-ups, wildlife. and countless landscapes for fun and to earn a living, I have never found a situation where aperture-priority works better than the other choices I prefer that include shutter-priority, manual, shutter-priority and Auto ISO, or just manually setting a known exposure for stuff too small to meter like stars. Can any one think of a situation where aperture-priority really works best in case it should be in the updated book. I never have found a reason to use aperture-priority, but that doesn't mean there aren't any! Thanks for considering this question.

Pano stitching and HDR.

99% of the time I use manual exposure settings and auto ISO. Software has gotten so good at denoising and detail recovery of images taken at ridiculously high ISOs that the ISO is hardly a factor in most cases.

Here is my quick take --
Though the real pros in this forum will provide a more exact optical if not scientific explanation --
All of this is based on the 35mm format

The 50mm is generally considered the angle of view of human eyesight when the eye is at rest --
Even though it is not quite
So every angle of view below 50mm can be considered a wider angle of view while all above 50mm can be
& is considered telephoto


Perspective and perceived angle of view make the 50mm lens on a 24x36 frame "normal" or similar to how the human eye-brain will perceive it. In reality human vision has almost 180° with both eyes, or 130°. But the brain mainly "focuses" on what's in the center. There are gender differences with women extending their visual focus to a much wider view, and men tending to use the center 46°. There is a theory that this difference is physiological - with men evolving to be able to see movement and evaluate speed (closing distance if chasing or being chased) and women evolved to be able to see and recognized patterns subtle color differences in cluttered scenes. Think of cavemen going on a hunt or being hunted, and women foraging in the forest/jungle for nuts, berries and leaves to eat. TMI I know, but interesting to me at least.

Last night I went to a local carnival and figured it was a good opportunity to practise some night time techniques using only manual mode. This is thanks to you all for recommending reading Understanding Exposure. I was a A type person before. To keep things simple used a prime 35.

So I taking pictures of the colorful rides and the folks having fun at the carnival. I was politely stopped by the police and was asked what I was doing. Simply told them taking pictures of the event. They said some of the parents had complained about me.

WOW...this happens to other folks. We had a brief discussion. One officer said if I wasn't with my SO, he would have asked to me leave. I told him I would stop taking pictures of people and focus on objects. He seemed to be ok with that. It was not too long after that we did leave anyways.

This got me thinking, no doubt it was a mother that got freaked out. What did that one person think a pedophile or some other malcontent was going to do with the pictures of the their kids in an evil way. As a parent not sure how I would have reacted (my kids are grown up and I don't have to worry about stuff like this). Is this simply something they have seen or read in the news that should be reported and action taken on or do they have valid reasons to react this way.

Just wonderin

Years ago I was asked to not take or use photographs by a mother who ended up being involved in a WITSEC situation. Always respect the needs of the possible people that may be in your photographs - it could really mean life or death for them.

If a photographer takes a picture of someones private property "old homesite"and then sells it.....is this ok or can the photographer be stopped?


Contact an attorney for the correct answer - one that will hold up in court.

A photographer has to ask for permission (property release) to use such a photograph commercially. However, if the image is for personal or editorial use, it usually does not require permission. Including such an image in a book about houses maybe not. Featuring that image on the cover of a book about similar houses requires a release.

But I am not a lawyer. Just a retired photographer.

Please don't shoot the messenger! I'm not suggesting FF shooters go out and sell their equipment and buy APS-C cameras and lenses.

Booray Perry, professional photographer posted an interesting video on YouTube yesterday that I thought I'd pass along: https://youtu.be/_fOh2LiCc84. If for some reason this link doesn't work, you could watch it on YouTube by searching for APS-C Beats FULL-FRAME.

In a nutshell, he says that advances in technology over the years in sensors, software, and APS-C lenses have enabled APS-C cameras to catch up to FF cameras. So, if you're starting out in digital photography, you should give serious consideration to buying an APS-C camera because they're smaller, less expensive, and now just as good as FF cameras. He says camera manufacturers such as Canon, Nikon, Sony, Fuji are devoting much of their R&D to improving APS-C sensors and lenses because that's where the future is. (And in 5-10 years the same thing will happen with micro 4/3 cameras).

He draws the analogy that that's what happened to medium format cameras, when FF in essence "caught up and was good enough" for the masses. Medium format became "niche" cameras, and the world moved on to FF. He says the same thing has already happened in the world moving to APS-C, camera companies realize this and are making huge investments in APS-C and rolling out more and more APS-C cameras. The general camera community is now starting to realize this.

Just some food for thought, especially for new digital photographers just starting out with their camera/lenses purchases. I certainly don't expect many FF shooters in general to convert to APS-C.

I realize this is just one professional photographer's opinion. Just found the video interesting.

I use Nikon full frame DSLRs and a Sony RX10m4. Both are good for what I need them to do. They do not replace each other. I shot APS-C until I got a D700 and after that I sold my D200 and D300S because even with both cameras D300S and D700, there was no comparison. Where the difference is primarily is when you make a print. The D700 (and all subsequent full frame cameras) do not need to enlarge the image nearly as much as a APS-C camera thus preserving image quality and detail. Not that I haven't considered downsizing, but for me the D810 and possibly a D850 in the near future, still gets my vote. I shoot a lot of wildlife with long heavy lenses and so far I have yet to see an APS-C professional quality 300mm lens or longer. I don't know if the guy in the video covers this but I got bored after the initial shameless self promotion and first couple of points he made so I got distracted by something else.
