it seems you have issues with dust on the sensor.

I think that it's on the lens. I usually don't notice it through the EVF or the LCD screen when I'm taking the shot and I don't tend to look at the lens to see if there's dust on it. With that said, there might be some on the sensor as well, but cleaning off the lens usually clears it up nicely, but that doesn't do me any good for the shots I've already taken. I'm sure I could touch it up.

Easily post processed in RAW using a heal tool.

Edit: hell, I once post-process removed a bin (maybe it was litter) from a picture of a magpie in flight.

Spot the repeating pattern?

The healing brush - or content-aware fill in Photoshop in extreme cases - make stuff like this a cinch, and are invaluable tools. I've had long series of photos where every image needs 10-20 dust spots removed, and once you learn where on the lens they are it's relatively quick and easy. And of course the importance of removal varies with the visual noise/detail where they are.

I use the blower on the back element of my lenses once in a while - front element dust rarely affects anything, back glass is a big culprit. Except my 300 f4 that literally has no back element (first thing you see are the blades), so I have to be careful with it or leave it on a TC at all times.

But you did shoot at f16 - its hard to get completely dust-free images stopped down so far unless you live in a clean room. Since CC 2019 or so, PS' spot brush has been so quick and effective that I really don't clean my sensors that often anymore (but the brush in cmaera raw still sucks ass).

I hardly get the idea about this stuff... what did you mean? You can get it clean anywhere if you have the tools. The biggest hurdle for some is proper eyesight and poor light to see the dirty spots.

When did I say anything about not being able to clean or see? I meant stopping down past f8 on a solid background is when you see all the dust clearly. If just shooting at 2.8-5.6 you won't see any even if there are specks.

When I'm on a spree I shoot outdoors all day and swap lenses all the time. My D610 in particular loves dust and even with regular blower use and going through swabs, you'd be surprised how quick the dust comes back.

 

[Ferrum Master]

, you'd be surprised how quick the dust comes back.

Use same ESD practices as with PC and touch ground and discharge yourself and tools before you do something. Then no dust will attract as you don't have the magnetic field anymore. I have a air compressor at home for serious jobs, like taking apart a lens and clean, but cotton swabs are enough for the sensor cleaning, even on field or while on a trip, never was a problem really, just do it gently. The built in feature to shake dust off also works.

So, leave tomorrow for 20-day Canada trip. Looking forward to seeing actual wildlife.

Come home from a last minute holiday shop and peek out to the back garden.

See this.....

I feed the starlings....

By default, I feed the Hawks.

Were you polite and offered some ketchup?

I'm back in the US. London and the UK was great, it was sad to leave. Cheers folks!

It was raining so opted for the phone:

When I get back home, I've got some crazy Canada goodies to post. Even today, wife almost stepped on a small snake chomping a banana slug. Nuts. Beautiful. Still here for another 11 days.

Just be careful on the trip back home. I ended up getting COVID during the return trip back to the US from London.

Edit: On a bright note, I did discover that @Ferrum Master was right. I had some stubborn particles on my sensor. I got some sensor swabs and cleaning solution and cleaned the sensor just a moment ago. I'm hoping it'll clear things right up.

At job I have set of these. Does the job also.

Used my phone

 

[Aquinus]

I saved another victim from my in-law's pool. A couple cropped close ups as he (she?) enjoyed posing for me.

[Aquinus]

This is why I bring my camera even when I don't plan on using it. You never know when an opportunity arises. It was foggy out, but I was able to get pretty close.

400mm, ƒ8, 1/400s, ISO 500

Too many pics and not enough time to sort... This is just a small selection.

These were all taken with the EOS R7 and the EF 100-400 mkII (on EF-RF converter). Some ISO's were as high as 6000. These were shot over 3 1/2 days at Knight Inlet Lodge.

All images scaled down for TPU upload (originals are 3-4x the size and pixel resolution).

A bear...

Another bear...

Juvenile eagle failing to recover bear's salmon...

River otters at 6:00am... (my wife and I were treated to 15 minutes of play time. Nobody else saw them).

Orcas also playing.

Bear cub on estuary, cute little girl.

And Mummy bear. TBH, we were close but the guides knew what they were doing. If the wife and I had been solo, if we'd gotten this close to her cub, I'm not sure we'd been able to come home intact...

Not too good, too cloudy and shot through glass on a moving vehicle. Quick edits in MS Photos.

Spoiler: Pix

The last one is not too bad for being shot at ISO1000 (oops) and with the setting sun in frame.

Location: west of Calgary, east of Salmon Arm, up in @tabascosauz neck of the woods. There is a forest fire nearby so it was really hazy.

We just had a plume of smoke haze from the other side of the continent for the last couple of days. When it gets real bad, you can even smell the smoke on the wind, even all the way here in New Hampshire. Sometimes if we're lucky, it'll coincide with a couple clouds and a nice sunset. Not this time though.

Heck, when there were really bad forest fires in California a few years ago we could see and smell the smoke in Norway.

Yup, kind of like how sand from the Sahara can end up in the southern US. It's almost like we're all on the same planet!
