I use aperture Priority to control the Depth of Field [DOF] ... either wide open to control the blurriness of the background or to obtain the most DOF, while taking pictures of flowers. At times, to attain the desired effect, I have to increase the ISO, or use a tripod, particularly using f/16 to f/22 in a poorly lit situation.

Good Luck.

I have a question for the OP. I haven't check out my camera to see what it can do. However, if there is a way to set minimum shutter speed then what do you want the camera to do when the minimum shutter speed isn't enough? Increase the ISO? (in this case just enable auto ISO). You want it not to release the shutter or yell at you?

As an alternative to letting the camera choose, consider this. On my D750 I have reprogrammed the video record (red) button to set ISO. Yes, it is programmable and reverts to its intended use when you switch over to video mode. In aperture priority I can then set the f/ to my creative needs and watch the shutter speed in the viewfinder. It is an easy adjustment to press the red button and simultaneously turn the thumb wheel to adjust ISO on the fly to meet the shutter speed I want. Once you get used to it, it becomes so simple and you easily gain complete control.

If you are concerned with the shutter speed . . . why are you using aperture priority??????

When you use aperture priority, what you are telling your camera is that aperture is the most important setting to you. I don't understand why so many here seem to think aperture is so important when many of them can't even focus properly.

If shutter speed is so important, use shutter priority!

Keep in mind that all settings other than manual are automatic settings. All automatic settings take control away from you and give that control to the camera. You can't have it all.

It sounds like what you are asking for is the ability to set a priority Aperture, and then to set a range for the shutter speed, with a maximum and minimum. Or at least you want to set the shutter to automate, BUT with a max or minimum.

Never heard of any camera that would automate and effectively set a priority Aperture and then also allow the shutter to automate, but with limits high or low.

Sounds like the camera manufacturers dropped the ball on this unique automation feature. It's an interesting concept, but............???

The manual work around (full manual) would work, but that's too obvious, involving changing settings.

Is there a way on Aperture Priority to allow the camera to automate shutter speed, AND IN addition, bracket shutter speeds? Just leaking some thoughts out here.

There are no "semi-manual" or "semi-auto" modes....

They are either manual or auto exposure modes. Period. Either you are setting everything yourself... or the camera is setting something automatically.

M and B are manual modes (B or "bulb" for extra long exposures.... i.e, anything longer than possible with M).

Aperture Priority, Shutter Priority, Program and Manual-with-Auto-ISO all are auto exposure modes.

All these manual and auto exposure modes have their uses. They can even be necessary, for some shooting situations.

Any time you are using any of the AE modes, it's on you to keep an eye on the other exposure parameters that the camera is choosing for you, that those are staying within a usable range.

Some cameras also have even more automated "scene modes", which take the automation farther and override other camera settings, in addition to using one or another of the above AE modes. For example, a "sports" mode would likely use Shutter Priority, a continuous autofocus mode, and set the camera to do high frame rate, continuous shooting. A "landscape" mode might instead set Aperture Priority, with an emphasis on smaller apertures for greater depth of field, single shot autofocus and single frame rate. "Portrait" mode might set up the same, except with an emphasis on larger apertures for shallower depth of field effects. These different modes also often make decisions about color rendition and contrast. And "scene modes" often dictate what type of image file is saved (JPEG versus RAW) and prevent Exposure Compensation from working.


Personally, I never use any "scene modes". I want more control over what my camera is doing.

Someone suggests it above, so I feel the need to comment....

I would absolutely never use Auto ISO with any exposure mode other than Manual. Using Auto ISO in combination with Aperture Priority, Shutter Priority or Program simply serves no useful purpose I can think of and makes it more unpredictable what the camera will do.

I assume the D750 can do Exposure Compensation with Auto ISO/Manual, too. Most newer cameras with Auto ISO can. Earlier cameras that couldn't, I wouldn't use Auto ISO at all. Exposure Compensation is essential with any auto exposure mode. I'd also look for either a "ceiling" that can be set on how high Auto ISO can go, or a readout of what ISO is being used in the viewfinder so I can keep an eye on it.

If... some day... cameras can do all the automation the way some folks seem to think they should... Well, we won't need photographers any more, will we?

Generally no. If you're shooting aperture priority you're telling the camera to select the other settings, ISO and shutter speed. To select both for one shot you generally need to be in full manual.

On my camera if I set the camera to A mode and auto ISO on then I set the max ISO the same as the min ISO when the light drop to the point the shutter speed is below 1/focal length (this is by default and can be changed) it tried to increase the ISO but it can't so it would flash the ISO number in the viewfinder. The same thing happen when the the light is too bright and the max shutter speed isn't fast enough it also flash the ISO number in the viewfinder.

Take a test shot. If your shutter speed is too slow, adjust your ISO. Never shoot in auto ISO. You never know what the camera will choose for either ISO or shutter speed. Make your initial selections for aperture and ISO and adjust the ISO if necessary.

Another suggestion is to shoot in Program. That allows the user to set the ISO manually reflecting the current conditions. Then upon composition the user can roll through "equivalent exposure settings" showing the Shutter Speed and Aperture from min to max for the lens/body combination. Simply decide to roll the dial to the desired (for example) aperture for desired DOF and the equivalent SS will be set also. OR, for a desired SS to control camera ssshhhaaake and or subject motion.

I've never used P myself, but when the OP posted I got my camera out and figured why there's an appeal. Some Nat's Geo Photographers (who have given workshops I attended) who are more content oriented rather than photo geeks call it "P for Perfect!"

It is an option like all the rest. The result is just another way for navigating the exposure triangle. As an old film guy, ISO was always an given for 24-35 clicks with some "push room" for a B$W roll. The film choice for a shoot reflected the desired graininess or not and the anticipated light levels and/or the speed of movement of the subject--or the wind induced subject movement of the subject. And, of course what color (if any) palette, saturation, grain type and development type desired. While I never considered "P" mode before, I guess I'll open my mind to auto ISO and hope to be surprised that it too is a valid way to shoot. Good heavens, could auto WB be next???? How can I not tell the difference between flash, fluorescent, tungsten, Halogen, cloudy, shade and full sun. But we do move about and the out door conditions change as do indoor light sources. And what the heck, I shoot RAW so I can always fix it in Post!

After a re-read, I think I'm likely to stick with AP and TV (Shutter Priority) for the bulk of my and held photography. And Manual is the king of the tripod. Control, control, control.

You have three variable available: shutter speed, aperture and ISO. In Program, the camera adjusts all three per some algorithms the manufacturer created to provide the best image for the situation. I think it takes into account the focus distance if you are auto focusing or manually focusing so it can de cide to optimize for a portrait or a landscape. When you lock down any one of the three variables the camera applies the same algorithms with a extra degree of limitation, again evaluating what it thinks you are composing. When two of the three are locked, it can only vary the remaining one and probably ignores the algoritm all together since it assumes you know what you are asking for. Manual gives you total control to make a poor exposure on your own and the camera program will not interfere. This is how I understand modern digital cameras go about the business. If I am stating something wrong or not the way it works, I would really appreciate any corrections. The only time I get bad images is when I take full control or make a stupid, forgotten adjustment of white balance or another parameter that throws everything into a nonsensical mess.

I haven't read all of the comments but in those that I have read there appears to be a lot of noise. I do agree that going fully manual might be better but as conditions change you will probably have to PP lighten or darken each file. I do what you are attempting probably about 80% of the time. Here's how. Select the aperture you want , find the worst condition (darkest) you will be shooting in and move the ISO up until you have the minimum speed that you can tolerate. The advantage of this is that the speed will adjust to the light reducing the PP required. Just be sure lighting does not get worse during the shoot or you may have to readjust the ISO

I don't know that model either but, most cameras DSLR and MILC today provide a way to set a minimum ISO or minimum shutter speed. It is in the manual.
