Your Canon Photos No. 9: 2nd to 8th July 2023

Here's one of my flower shots from today:

Freedom to grow. Freedom to express yourself. by simple.joy, on Flickr

I just love how unruly some of those are.

very abstract mate , i like it.

from one extreme to another dof.

David,

I have used 15mm FL with my mirrorless lens. If the buildings and subject matter are close, then there will be that wide angle distortion. It's OK...afterall...it's our art. What I try to do is keep the center part of the picture straight and then to each side you can see things leaning to the left or to the right.

Here's an example.

Model - Canon EOS M50m2
ExposureTime - 1/320 seconds
FNumber - 11
ISOSpeedRatings - 1250
ExposureBiasValue - 0
FocalLength - 15 mm
Lens Model - EF-M15-45mm f/3.5-6.3 IS STM

Simplejoy and David,

Doesn't the FOV also depend on whether a person wears glasses or not? 😀 I read that it does change quite a bit.

Simplejoy,

Your flower picture is very pleasing. I enjoyed seeing it.

Donald,

I like how you showed photos with DOF from one extreme to another. I usually only show flowers with a large (deep) depth of field. I think it's just my personality to want to keep things in focus, with no softness. I only like color too. I don't know...we are all different. 😀

No, these weren't in a field, they were in a wildflower bank - basically a long mound covered with grass and wilflowers.

Digi,

Thanks for your comments. Possibly my eyes work different from yours (I dont find any difference perceptually with or without my glasses), but can you be more specific about the wide-angle distortion distortion you see in the 16mm lens?

David

Digi,

Surely, if you keep the lens horizontal it prevents the leaning effect at the sides — which can also be corrected in software.

(Of course, trees are a problem, as they are not always vertical in nature!)

David

David,

I can't see the EXIF data any longer, so I don't know what photo was taken at 16mm FL. I was making a general comment; I didn't analyze them. I think what you are doing is fine. I see wide angle distortion all of the time in my photos, but then I look for it. It's more evident for example if there's many vertical poles or posts in the photo. Look at the doors and windows and see if they are perfectly straight on either side. If they are straight, then you don't have wide angle distortion.

I also see telephoto compression often in my photos too. So I know that pictures can distort reality. But that's OK...as one famous photographer said, taking pictures is creating instant paintings. He was a painter too, so he appreciated that we could create art with a push of a button. I also look at photos as art.

A little edit: Even though I can't see the EXIF data (it comes and goes on DPRevived for me), I believe from what you wrote the second picture was taken at 16mm FL. Again, look at the doors and windows on either side. The "leaning" is very slight. When we are closer to the subject matter the wide angle distortion is a lot more. By the way, I really like your photos taken from that camera. I suppose I should get one of those full frame cameras. What do you think of the Canon R? The price is not too expensive. I would just start with a kit lens.

DIg,

Thanks for your helpful comments. If I understand you correctly, there are two main components to this distortion at the edges:

1. Vertical lines not vertical
2. Straight lines not straight.

I dont like either of them. No.2 depends on the quality of the lens. Distortion in RF lenses is controlled and for most of the series is corrected in camera (jpeg files) or in software (raw files).

As I said above, No.1 is a question of holding the camera horizontal or, when that is impossible with tall buildings, etc, it can also be corrected in software.

Yes, but I find the two distortions off-putting in the case of photos of buildings.

I have also noticed this and will report it now I know it is not just me! If you refresh the page (F5 on PC) the EXIF returns.

Then that is my fault: leaning is avoidable in the final result.

I was amazed at the improvement when I compared the RP to my 5D, and I still dont know what is responsible for it. The R is a good camera, though some people do not like the ergonomics of the rear controls. I still have the RP, and it is no slouch: it's only disadvantage is that the shutter stays open when you turn the power off to change the lens. If you are only going to have one lens to start with, I recommend the RF 24 -- 240 mm. When not doing silly tests like I have been recently, I use it a lot. But there are good reviews of both on Ken Rockwell (comparative) and DPR.

David

Edit: PS: I hope you dont mind, I have had a go at un-leaning your photo edges -- not as easy as with raw files, and I havent managed it totally; but less leaning. You have to lose some of the edges in the process!

Thank you simplejoy.

David,

Thank you for your comments. By the way, if you all don't hear from me today I'm off taking pictures again.

Hi Dunlin,

1 and 5 are my favourites, nice set.

Dunlin say's,

As a note, I've decided that my workflow, for now at least, is properly a JPG-only workflow. Before it was only temporary, but I've decided to stick with JPGs for now. I'm still shooting RAW+JPEG, but I'm not currently doing anything with the RAW file other than storing it.

You're wise to keep the RAW files too as improvements in photography software is advancing and very quickly. Some photos that I took a few years ago I would not of shown/printed because of the noise in the picture. Now I will gladly put them up on the forums because of Software, not only removing the noise but also giving back the detail that was lost in those noisy pictures. Who knows what other gains are to be had. I'm glad I kept all my photos.

I only shoot in RAW by the way.

A much better use of your weekend!

David

WEEKLY ROUNDUP

The holiday photos are still arriving: Mocha's from Cornwall, with nautical and nature features. Nearer to his home, Digirame captured some wonderful castles and other temporary creations in sand -- quite amazing in imagination and execution. Merlot provided family pics of a summer's day picnic in the Cotswolds.

Then there were Digirame's July Fourth parade and Steve T's impressive fireworks and a Japanese lantern.

Fotoworld caught perching birds. Galahs are new to me. I like the way birds space themselves out. Photobygms continued our nature study with a slow worm, resting cattle and stationary trees. Steve T countered with a skink. Mocha caught an egret coming in to land and apparently dancing on the water.

Steve T found a crop circle -- though too late to photograph the aliens making it!

Simplejoy's photos are never simple: nails like mountains, unusual views of flowers and a feather. DonaldB joined in the flower show and Dunlin also took varied pictures of Ox-eye daisies.

My contribution was wind turbines, yellow roses, and further advocation of wide angle views. We dont all agree about these, but I am glad they provoked a discussion.

Thank you all for a good and interesting week with 100 posts, and particularly for the interaction.

David

The new weekly thread is open here. Please start using it now.

Not sure what point you are trying to make.

Are you not aware that the photos you post can be produced by AI now?

It‘s not something I wish for but this is the kind of post helping the argument for a downvote button… Why do you find it necessary to say something like that?
