Hands-on review and freezing action test.<\/h2>\n<p><\/p>\n<p>The Profoto B1 AirTTL is a new battery powered flash unit that is based on the Profoto D1 Air series but is made to take on the road. It has the same housing, the integrated reflector, and the built-in receiver that works with the Profoto Air transmitters.<\/p>\n<p><\/p>\n<p>By using the Air Remote TTL-C for Canon or Air Remote TTL-N for Nikon, you have the ability to be up and running quickly. We know that Profoto equipment is known for quality products, the question becomes, how well does the Profoto B1 AirTTL and is it suitable for working in a product photography setting?<\/p>\n<p>&nbsp;<\/p>\n<h2><em>Profoto B1\u00a0AirTTl on the beach:<\/em><\/h2>\n<p>[\/et_pb_text][et_pb_video src=&#8221;https:\/\/www.youtube.com\/watch?v=nB1KMls5ZBE&#8221; image_src=&#8221;\/\/i.ytimg.com\/vi\/nB1KMls5ZBE\/hqdefault.jpg&#8221; _builder_version=&#8221;3.19.7&#8243;][\/et_pb_video][et_pb_text _builder_version=&#8221;3.19.7&#8243;]&nbsp;<\/p>\n<h2><em>Cool facts about ProFoto B1 AirTTL monolight:<\/em><\/h2>\n<p><\/p>\n<h4><em><strong>Simple and easy to operate controls:<\/strong><\/em><\/h4>\n<p><\/p>\n<p>As you can see, the back of the unit is where you can control manage the settings.

For a studio photographer the major disadvantage is that it is only battery operated. It is rated to get around 220 flashes on a charged battery unit (this is variable based on the power used for each shot). This means that you would have to have two or three batteries available for the typical shoot. It takes around two hours to charge a battery (one with the optional quick charger). There is also no warning prior to the battery running out.<\/p>\n<p><\/p>\n<p>The B1 has the ability to recycle in 0.1 to 1.9 seconds, but can also pop off around 20 shots per second in Quick Burst mode which might be useful when shooting a sequence of high speed shots. The duration range goes from 1\/1000 sec. at full power to 1\/11,000 sec. at minimum power in Normal Mode and can go to 1\/19,000 sec. at minimum power in Freeze Mode.<\/p>\n<p><\/p>\n<p>I think that the Profoto B1 AirTTL can be useful to the product photographer given that they have enough charged batteries to work a complete shoot. The quality is there and the ability to capture for both color quality when working in standard situations and the ability to freeze motion when high speed capture is needed. This system would be especially useful for the photographer who has to travel on location frequently and not have to lug larger power packs.<\/p>\n<p>[\/et_pb_text][et_pb_text _builder_version=&#8221;3.19.7&#8243;]<img decoding=\"async\" class=\"alignleft wp-image-6438\" src=\"https:\/\/www.photigy.com\/school\/wp-content\/uploads\/2019\/02\/9-11.jpg\" alt=\"\" width=\"160\" height=\"160\"><\/p>\n<h2><span style=\"color: #1f3b4a; Text-align: center;\"><strong>Pros:<\/strong><\/span><\/h2>\n<p>Short flash duration with the ability to freeze action.<br \/>\nPortable and powerful.<br \/>\nBoth Color and Freeze modes.<br \/>\nAvailability of Profoto light modifiers.<br \/>\nBag to hold all of your gear when traveling.<\/p>\n<p>[\/et_pb_text][et_pb_text _builder_version=&#8221;3.19.7&#8243;]<img decoding=\"async\" class=\"alignleft wp-image-6438\" src=\"https:\/\/www.photigy.com\/school\/wp-content\/uploads\/2019\/02\/10-11.jpg\" alt=\"\" width=\"160\" height=\"160\"><\/p>\n<h2><strong><span style=\"color: #cc0000;\">Cons:<\/span><\/strong><\/h2>\n<p>220 shots per battery charge is not really enough to handle most product photo shoots.<br \/>\nNo AC power connector direct to the flash unit.<br \/>\nNo warning that the battery is dead before it stops working.<\/p>\n<p>[\/et_pb_text][\/et_pb_column_inner][\/et_pb_row_inner][et_pb_row_inner admin_label=&#8221;Row&#8221; _builder_version=&#8221;3.0.47&#8243;][et_pb_column_inner type=&#8221;4_4&#8243; saved_specialty_column_type=&#8221;3_4&#8243; _builder_version=&#8221;3.0.47&#8243;][et_pb_text _builder_version=&#8221;3.19.7&#8243;]<\/p>\n<p style=\"text-align: center;\">&#8212; More about Profoto B1 AirTTL &#8212;<\/p>\n<p><\/p>\n<h4 style=\"text-align: center;\">Download Specification and User Guide:<\/h4>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\">&#8212; Where to buy Profoto B1 AirTTL &#8212;<\/p>\n<p>[\/et_pb_text][et_pb_code _builder_version=&#8221;3.19.7&#8243;]<\/p>\n<table bg-color=\"color: #ff0000;\"><!-- [et_pb_line_break_holder] -->\t<\/p>\n<tr valign=\"top\"><!-- [et_pb_line_break_holder] -->\t\t<\/p>\n<td width=\"188\" height=\"300\" valign=\"top\"><!-- [et_pb_line_break_holder] -->\t\t<a href=\"https:\/\/www.bhphotovideo.com\/c\/buy\/Profoto_B1_500_AirTTL_Battery_Powered_Flash\/Ntt\/Profoto+B1+500+AirTTL+Battery+Powered+Flash\/N\/0\" target=\"_blank\" rel=\"noopener noreferrer\"><img decoding=\"async\" class=\"alignleft wp-image-6438\" src=\"https:\/\/www.photigy.com\/school\/wp-content\/uploads\/2019\/02\/11-8.jpg\" alt=\"\" width=\"167\" height=\"189\"><\/a><\/td>\n<p><!-- [et_pb_line_break_holder] -->\t\t<\/p>\n<td><!-- [et_pb_line_break_holder] -->\t\t\t<!-- [et_pb_line_break_holder] --><a href=\"https:\/\/www.bhphotovideo.com\/c\/buy\/Profoto_B1_500_AirTTL_Battery_Powered_Flash\/Ntt\/Profoto+B1+500+AirTTL+Battery+Powered+Flash\/N\/0\" target=\"_blank\" rel=\"noopener noreferrer\"><\/p>\n<h4  style=\"color: #cc0000;\">Profoto B1 500 AirTTL Battery Powered Flash<\/h4>\n<p><\/a><!-- [et_pb_line_break_holder] -->Optional Remote Control with Air TTL-C\/N<\/br><!-- [et_pb_line_break_holder] -->Full E-TTL II with Canon Cameras<\/br><!-- [et_pb_line_break_holder] -->Full i-TTL with Nikon Cameras<\/br><!-- [et_pb_line_break_holder] -->500W\/s, 9-Stop Power Range<\/br><!-- [et_pb_line_break_holder] -->Lithium-ion Battery Powered<\/br><!-- [et_pb_line_break_holder] -->Up to 220 Full-Power Flashes<\/br><!-- [et_pb_line_break_holder] -->Flash Duration: 1\/19,000 \u2013 1\/1,000 Sec<\/br><!-- [et_pb_line_break_holder] -->LED Modeling Lamp, 20 fps Burst Mode<\/br><!-- [et_pb_line_break_holder] -->0.1 \u2013 1.9 Sec.
