D 7200 has WiFi and NFC. Bought the WU-1 I think it is called for my D3200. Works but has a learning curve.

Thanks for the info! Those shots look incredible, they have a lot of the postive effects of the HDR's without that pesky "edge glow" which I don't like. I have been doing some luminosity masks so I have an idea of what you are talking about there, the ability to target narrow tonal ranges that are sort of lost in the original, whicy is what HDR does in a different way, or maybe even similar to a kind "tonal equalizer", in music where there are a series of sliders that target more narrow ranges of tone rather than just bass and treble. However I admit "layer masks" are something whose use and meaning has still eluded me, despite several attempts to get a handle on them. Do have a few words in a nutshell about what they do?

It's actually a lengthy topic, but in a nutshell, layer masks either allow or block (or somewhere in between) an effect from the layer they are associated with. Black layer masks block everything, white let everything show through - everything between black and white (grays) will allow varying amounts of effect though, depending on how dark / light it is.

For instance, if I use a curves adjustment layer and drag it down to make everything darker, I can place a black layer mask in and block the entire effect. Then I can go though with a white brush and just add the effect to where I need it in the image.

Actually, I should do a video on this, it would make a good topic and it's one that comes up quite a bit.

That is my solution also.

I've dealt with this same issue, as I have been using BBF exclusively (when hand held) for a couple of years. I've found no problem at all with use of the cable release when I choose to do so. I've set a custom setting on my Canon 5DII that simply returns the camera to shutter release focusing when I'm using the cable release. No confusion, as I only use BBF when hand held and it's not an issue when on a tripod using cable release.

No no, the OP wanted a way to avoid turning off BBF, which, at least on a D7100, automatically disables BBF for the use of the IR remote.... go back to shutter release and BBF is automatically back on.


I suggested he turn off the autofocus, not the BBF.

I use a cable release instead of a timed release so I can time elements in the shot.

For example, I shoot a lot up along the shore of L. Superior. A cable release allows me to time me shot for the perfect wave - can't do that with a 10 second timer.

Another use is for combating wind in a scene. You can lock up your mirror and just wait till it stops (or slows down) for a second and then snap the shutter before it starts again.

So, timer release works good sometimes, but there are times a cable release can be your best friend.

The two shots below are good examples of when using a cable release to catch the perfect wave paid off:

Good point! I'm convinced. BTW...I watched your BBF video (recommended on UHH) several times. It's excellent. At the end you do mention using BBF for landscapes but you didn't say anything about the implication of using BBF and cable release. Your video helped me understand that I needed just a little more info. Thanks very much!

Everyone's mileage is different on this one. I similarly split my subjects between wildlife and landscape. I use BBF and half press for birds and wildlife, depending on my mood. I use BBF exclusively for landscape - and I often do panos and sometimes hand-held. I do not use a remote shutter release. I carefully compose, focus, and shoot. If I am on a tripod because I am using a long shutter speed, as I often do with moving water and ND filters, same deal. The last thing I want is the half-press changing my focus point if I accidentally release pressure on the shutter button.

While BBF is often promoted for action - few people actually cover why. BBF is a way to avoid switching the camera from Single to Continuous focusing mode. With BBF, if you want to lock focus, press BBF-focus-release BBF-shoot. if you want to track, press and hold the BBF while tracking. Landscape requires the former, moving subjects require the latter. A subject that moves and sits still is best served by BBF because you don't have to switch camera modes - and that is why so many photographers use it.

Shutter delay and mirror lockup and other somewhat "heroic" measures are just to make up for an inadequate tripod and possibly poor technique.

I use none of those.

Great, clear response. I think I'm at least getting the concept. Steve Perry does mention your points in his video but my brain needs a bit of repetition. Now I must practice more in the field. BTW, your photos are gorgeous. I aspire for mine to be as good. Another question.....mirror lock-up. You call it a "heroic measure" Please elaborate. Do you have unusually steady hands??

Even zooms that do include a distance scale, usually don't provide the Depth of Field scale needed to most quickly and easily do hyperfocal distance focusing. There would need to be a different DoF scale shown on the zoom for each focal length, which is impossible of course.



Actually most, if not all, manual focus one ring Nikkor zooms, from 28~50 to 360~1200, have a depth of field scale.

2 sec delay puts the mirror up for less vibration, Right?

Not on my Canon 5MK III. Mirror lock-up is a menu item only.

Ok, I may also be mixing apples and oranges. On my Nikon 2 sec, delay (self timer) does not lock up the mirror. But, I also have exposure delay mode that does lock up the mirror for 1, 2 or 3 sec. I believe using LV also puts the mirror up. I use live view or exposure delay mode in conjunction with a cable release while on a tripod. I write this to respond to Bloke who posted;
"When I use a cable release I manually focus using LV set 2 sec delay on the shutter and use the cable release"

If you are in LV, then the mirror is already up. At that point either the delay or the cable release would handle any vibration. I just wasn't sure exactly what you meant. I often just use the delay, since I may not have a cable with me, especially since my cameras use different fittings on the cable...

Here is a picture and description of a typical Nikkor zoom with a depth of field scale:

I've seen the light about BBF and I've been practicing regularly. I agree that it works great for hand holding the camera/moving subjects. A problem is that "everyone" seems to say to set the camera for BBF and leave it there!

My dilemma is...I take a lot of landscape photos using a tripod and cable release. It seems counterproductive to use BBF and then snap the shutter with the cable release. Obviously I'm TOUCHING the camera to do this. (The cable release cannot be set to use BBF). Should I be going back and forth between BBF and half-press depending upon what I'm shooting. I've not seen this discussed. Please comment

My cameras are set to back-button-focus at all times. I do not have any trouble using a remote (well, mine is wireless)!

So are mine....now. After all this discussion, I think I understand. Thanks for helping me through this learning issue.
