Cats

Very good shots of cats in your area. It's hard for me to say which is my favorite, I love them all.

I like both of these; but my preference is the first one. I must admit, I've never thought of using the framing as a subject. It works! You did keep something within the frame; but it is out of focus and makes the viewer's eye return immediately to the framing which has really good detail. Very creative.

Thank you Erich, #1 is my favorite of the two also; but I really do like the novelty of #2, including the strange bokeh with the crosses.

Perfect (and I agree) - the “equivalent image” addition makes it universal and easily understood.

Sorry no, I’m not neglecting anything. Note that I pointed out that it depends on whether we’re discussing equal distance or equal FOV (which is determined by distance, FL and format). Just pointing out that one needs to define the terms rather than make a blanket statement as to DOF vs format. I could have changed the lens from 50mm (crop) to 80mm (FF), but chose to change the subject distance for purposes of illustration.

So just to summarize here for an equivalent image the larger the format the smaller the DOF. Which is the only logical way to compare formats without getting into the weeds.

Courtesy DOFMaster: for the same subject distance and aperture, larger format = greater DOF. Now if you, move closer with the FF to get the same field of view as the crop, then the result changes.

What your neglecting here is that the focal length of the lens and the format "Play together" in the overall picture. For instance a 25mm lens in a 4/3 format is roughly equivalent to a 50 mm lens in 35mm or ff. And that is roughly equivalent to a 75mm lens in 6X6cm. Once you take those differences into account the smaller the format the greater the DOF for an equivalent image. You can't hold the lens focal length constant and get comparable images when moving between formats.

Well, from my reaction and the reaction of Linda (who should be busy getting someone to start that landscape forum

) find out how it happened and repeat it. It is very subtle and cool!

I love backlighting and your isolated branch in #1, with dark background, is very eye-catching. #2 seems more like natural framing, but there is not a subject in the frame. Cropping into two separate photos (vertical, where the break is at bottom) kept the soft, appealing backlighting and gave me very pleasing gentle lines.

I'm also curious if there was a screen because I achieved similar cross-hatching recently shooting through a screen door. Very cool.

Thanks Linda, to satirize Marshall McLuhan: The frame is the subject. And no, no screen, no idea what caused those crosses.

Was there a screen as well as a window? I ask because the second shot has a rather interesting cross shape in the Bokeh. Or is the Bokeh with this lens always like that? It is interesting.

I would probably dehaze in PP. Just to see what it would look like.

No screen; I saw the cross shape that you refer to as well, but have no idea where it came from, not characteristic of this lens. I did a dehaze with both these shots.

Actually the smaller the format the larger the depth of field not the other way around.

Shot with Nikon D700 Nikkor-H 300mm/f4.5 Both of these were shot through a double window so there is a bit of smearing present but I think it adds to the images. As always downloading for best viewing is recommended.

Scan negatives versus copy to camera?

Before purchasing any scanner viewing third party tests of scanners is important. I find it interesting that almost no one's claims of scan resolution live up to the test results. It seems to be a case of who is the biggest liar of the various brands. Here is one testing website:

A Splash of Color

Thanks everyone for your kind comments. This was shot out of one of my second story windows with the pear tree across the street. The sky was mostly cloudy but I managed to catch a bit of sun breaking through the clouds to light up the leaf surfaces facing to the south. That's what gives some of the leaves extra glow that can be seen here. It truly is all about the light.

Thanks Dave, it was a Nikon D700 with the much, and wrongly maligned, 24 - 120 f/3.5

Thank you Graham, I would have guessed all day and not hit on the D700 (and I have one.) Many images that get posted on this and other sites have a bunch of digital artifacts that become visible if one downloads the image and hits the +, I don't see any of that in your image here. Once again, very good work.

Really good work there. Focus on the bird is spot on.
