My obsession with a photo being level has nothing to do with the subject within in the image. Unlevel photos hanging on walls bug the crap out of me too.

Without the in-camera digital level, I am terrible at as well. And I must say, using the leveling feature every day with my work, I think it works great.

To each their own. The Fuji also has a level in the viewfinder as well and I rarely have to level in post. Works for me. YMMV.

"Dr. Livingstone, I presume?"

But back to DOF, at the risk of stating what is mostly known, the only point in focus is the actual focus point, the hyper- focal distances are "presumed" to be acceptably sharp. This is a mathematical formulation "assuming" viewing distance and lots of other factors. Anyway I think two people looking at some distant branch could easily differ as to whether it is sharp or not but why is that important anyway. Obviously if you have a cover shot of an Owl, you want it to be sharp but..............

Rob is correct; the technical term for the measure of sharpness is, I believe, "within the circle of confusion." The value assumed in the calculation shows on the calculator I liked to.

J, that depth of field chart is interesting. I should have left my aperture at f8 since it doubles the far limit focus range. Thanks for the link. I will have to put that app on my iPhone.
Yeah that sounds like the cause of what I'm seeing. But JDRMC says everything looks sharp so this may be more something with my eyes than with the picture.

Another factor is contrast. We generally interpret contrast as sharpness. My 100 yr. old lenses are actually pretty sharp in the center (Tessar, Heliar, Dagor) stopped down a bit, but since they are all uncoated glass they have lower contrast (especially with color images,) and that makes them appear less sharp. I once took some shots using a resolution test target with a couple of Tessars and a modern Nikon lens. In the center they were actually pretty close in lines resolved. How does contrast affect modern lenses? When shooting fog/snow/dust etc., the contrast is similarly reduced. I generally like a softer look, myself. I've noticed that night shots with flash appear very sharp even though in effect the "shutter" speed is at most 1/1000s. This is partly because I shoot the flash with no modifiers (other than reflectors and sometimes grids), which creates high contrast. I've come to think that at least some "sharpness" is in the eye of the beholder.

I don't think I said that. I try to avoid opining on sharpness as I am one of the worst judges around.

What I said was that f/7.1 vs f/8 does not matter for the shot. And that the distant hillside showed reasonable amounts of detail. And I'm sure I muttered about all sorts of other stuff ...

BTW, Dave B, you going to upload that NS show shot you included in a previous post, or is it already on RP?

Oh sorry. As to the other stuff it sounds like you were right about the focusing issue and it was more of the shutter speed and panning.

I use it when I'm doing long exposures on the tripod, and I agree it does work well. Since I picked up a nice ND filter, I find myself doing a lot more daylight work in that manner. If only the pro canon bodies had the time on the back display like the rebels..

The sharper you can make landscape pics the better. I think if you compare DaveB's with Massart's you can see the difference. That's why landscape photographer's they use hyperfocal distances so they don't give up any DOF. And these two pics in this thread are as much landscapes as train pics.

Here's some good examples. Obviously these are great pictures for many reasons, but all of them except one have sharpness throughout the picture, from foreground to the horizon. Maybe a better way to put it is that they have sharpness in all the parts of the picture whose details you want to be able to discern:

Dave B, you are new-ish to the forums, here is how we link RP shots.

[photoid=xxxxxx]

where xxxxxx is the ID of the image. Putting in "514456":

Or, I suppose, maybe you did it intentionally.

I'm not DaveB! I'm SFO777...just posted his photo. Is it a copyright transgression to post the full-sized photo or just a bb faux pas? I guess it can make a quoted post full of pics annoying as heck, is that the reason?

No, no, just trying to be helpful.

But yes I found it annoying.

Many of the serious landscape photographers I know use tilt/shift lenses to squeeze out "wall to wall" DoF. That's one of the reasons large format is still alive and kicking--the lens movements that are available. I once almost bought into the Canon system to get that wonderful 17mm TSE, but then my wife slapped me and I regained my sanity. (Thanks hon, I needed that!) Often having all of a landscape sharp looks nice, but the landscape shooters I really admire (most of them British) use selective DoF where parts are sharp and parts are deliberately pleasantly blurred. Done well, it REALLY makes your subject pop! I've been experimenting with my f1.4 lenses shooting with very shallow DoF and delibetately blurring the train, but so far haven't come up with anything I consider a grabber. It takes some practice to pull off. I do agree that most shots of trains are basically landscape photos (frame filling wedgies, no.)

Default Re-dux gets a screener poo-poo

Re-shot the scene yesterday. No foreign power to add a splash of extra color but I did use a tree as a framing element, take notice Jim. Cloudy/common rejection. Maybe the screener doesn't like Subarus.

You need some elevation at that location to get the train trailing off around the curve.

Not possible from that location. Even a 25' tripod wouldn't give me the example you are showing. A much longer curve is present.

CSX in Western Michigan?? Who da' thunk? Nice shot BTW even with common power and cloudy skies. See no Subaru so it was accepted.

Well, seeing as those are CSX tracks, no surprise to see a CSX loco on them.

That's actually linked from my imgur acct. I haven't submitted that shot to RP (and hadn't planned on it).

Front license plates suck. I'm glad I live in a state that doesn't require them.

what about getting much much closer to the car and trying to angle it one direction. Use your hyperfocal distance to get everything nice and sharp.

Maybe have the car angled to the left. Maybe you could get some reflection of the train off the side of the car?

Just ideas.
