Do you like TTL or Auto Flash?

It seems to me that Auto Flash appears to be more correct on the exposure versus TTL.
I will need to try some samples.

If your camera & flash are TTL compatible and 'play well' together, TTL IS the way to go, with 'plain' auto a close 2nd place. Both are so much easier to use than the old fashioned Guide Numbers.
IMHO, of course

Neither. I use manual flash and adjust the power on additional units as a ratio to the primary light source.
What flash units are you using?

Not sure what the difference between Auto and TTL is. My cameras (Nikon) offer TTL and Manual control. I shoot with my speedlights on manual using radio triggers and adjust the balance myself.

If you get better exposures with auto flash than with through the lens flash, then auto flash is probable more correct for you.

Good answer. I use a Sunpak 383 and use manual as well.
I have a Canon 530EX ll, used one time at an event on TTL and what a mess. Either overexposed or underexposed photos.
Now I am back to my sunpaks

Depends on the application.
Events, candids, I shoot TTL with my Nikon.
It's really very good.
Haven't used "Auto" in at least a decade or two (uses a sensor on the flash).
For just about everything else, I use manual.

Even though I shoot flash 95% in manual, I really like having TTL for the times when shooting in manual is not an option (TTL is a bit more complicated, but it definitely is one thing I don't want to miss (ever)!

Aren't auto and TTL (or ETTL) different levels of sophistication of the same concept?
At the end of the day isn't it the light coming through the lens the thing that really matters, and that can be controlled by the photographer (manual) or by the equipment (Auto / TTL / ETTL)?

Auto flash simply measures the light as it bounces back into a sensor on the front of the flash and is very old school technology from before TTL flash was available. TTL flash actually measures the light as it hits the CAMERA SENSOR and is is by far the best method of using any auto measured flash. Also, TTL flash is extremely easy to use, as you can control the flash ratio as it is mixed with the ambient light. That ratio can be changed right on the flash, or in the camera's flash power setting. For a pleasing fill flash effect, try a power ratio of minus 1 or even more.
Of course for studio settings or still life's, full manual everything is the rock solid way to go. For wedding receptions, location shooting in mixed and changing light, etc., TTL is absolutely the go-to technology. It works well with manual exposure on the camera, or with an auto mode such as aperture priority. My standard setup now is manual for the camera exposure and TTL for the flash exposure, usually bouncing the flash.

Auto was popular back in the day before TTL was available. It just measures light from a sensor on the flash, and not through the lens to the camera sensor.

Auto flash using the sensor on the flash or sometimes a hot shoe mounted sensor when using the flash off camera was the old school one but still works very well. Newer flashes don't support this Auto mode any more.
TTL for film cameras worked quite well as it measured the light intensity bounced off the film during the actual exposure.
dTTL, iTTL from Nikon or Canon ETTL for digital use weak preflash burst and measure this intensity with the meter sensor in the viewfinder and then set the power level for the actual exposure. This causes a bit of a delay.

That makes logical sense, but given the speed of light, does it actually make a practical difference?

Damn, I knew that. I can be a bit thick at times :oops:
