Optimal exposure settings requires a knowledge of how to balance ISO sensitivity, aperture level, strobe power and strobe proximity to the subject. Because strobe power varies dramatically not only between manufacturers and models but also when external elements such as umbrellas, soft-boxes and lighting gels are used, quickly determining correct exposure settings can be challenging at best, and frustrating at the worst. KeyLight PRO removes all of this guesswork. Easy-to-use calculators quickly and clearly display optimal ISO levels, aperture settings, strobe power levels and strobe-to-subject distances in an intuitive, familiar interface. For the more advanced photographer, the Key Falloff calculator will calculate the proximity of the strobe from the subject in order to meet a desired exposure value falloff over a specific distance. For example, the area behind a subject is 10 feet away, should be 3 stops underexposed relative to the subject, and the strobe is firing at 1/4 power and the camera is at ISO 400. What should the aperture setting be on the camera? With KeyLight PRO, the answer is a tap away. How many strobes does KeyLight PRO support? The Virtual Gear Bag provides an unlimited number of strobe makes, models and settings, and the Strobe Library provides over 100 pre-loaded strobe model configurations. The Gear Bag is readily accessible on all of the calculators, providing quick, easy and accurate exposure settings when swapping between your strobes. Only using one strobe? Keep multiple "set ups" in your Gear Bag under a variety of configurations: bare bulbed, gelled, soft-boxed, umbrellaed, neutral-density filtered, wall-bounced, go-bo'd. There is no limit to the number of ways the light from a single strobe can be modified. Create as many configurations for these light modifiers as you need, and know in an instant how to most effectively utilize them. KeyLight PRO. Control the light. ## KeyLight PRO Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple118/v4/e5/77/7e/e5777e58-19b9-24aa-6074-ba60518a6a19/mzl.pmmpznru.png/640x960.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/Purple128/v4/c1/54/6b/c1546b85-bd80-17b5-4c4e-552434dd211a/mzl.gmqntpyb.png/640x960.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/Purple118/v4/ed/53/78/ed5378f1-bb23-55e1-6a3a-179ef0368984/mzl.uuqgwcuw.png/640x960.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/Purple118/v4/ed/ac/61/edac6115-2789-d468-c6e6-e45c6a14cb68/mzl.ydobialn.png/640x960.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/Purple118/v4/48/57/bd/4857bdd8-b5ad-602d-9af6-3b6c2c70a3f9/mzl.ekrxdgsz.png/640x960.png) ## KeyLight PRO Rating Breakdown in United States - 5 stars: 3 (75%) - 4 stars: 0 (0%) - 3 stars: 0 (0%) - 2 stars: 0 (0%) - 1 stars: 1 (25%) ## KeyLight PRO Reviews in United States ### ***** "Works Great!" Running great on the iPhone 13 Pro MAX, and assists me in numerous occasions when it comes to photography setup in various situations. Not sure what the iPhone 12 guy is talking about- he’s probably very confused on how to open an application without a home button? I could even help him it’s that easy, but he may lack the mental fortitude to understand how to press buttons? I certainly have enjoyed the app and its complex calculations. -- Heizenjess, 2022-01-05 ### *---- "Does not work on iPhone 12" This app does not work on iPhone 12 and I fully intend to demand a refund and have my credit card refused to charge. -- Mrh3333, 2021-11-03 ### ***** "Wonderful app" I would love to see an option to select flash power divided into 1/3 or 1/2 Thank you for making this app. This makes the guesswork from film much easier. -- shoopdewhoop, 2016-11-14 ### ***** "Works great!" This is exactly what you need if your off-camera manual flash doesn't assist in these calculations. This takes the guess work out of determining flash to subject distance, aperture, or power. Just enter your flash's guide number and you're good to go. Thank you! -- teger33, 2014-08-13 ### ***** "Better than expected" Very handy for pre-planning a major shoot. -- "Shutterman", 2013-06-14 [View all KeyLight PRO reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## KeyLight PRO Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | Argentina | Photo Video | #241 | ## Apps Similar to KeyLight PRO - [PhotoPills](https://apptail.io/app/photopills-Sgd/united-states) - [Lghtmtr](https://apptail.io/app/lghtmtr-Wig/united-states) - [Cascable Studio: Tether & More](https://apptail.io/app/cascable-studio-tether-more-HAg/united-states) - [Lightme - Lightmeter](https://apptail.io/app/lightme-lightmeter-Tbv/united-states) - [测光表 Light Meter Ultra](https://apptail.io/app/light-meter-ultra-Auy/united-states) - [myLightMeter PRO](https://apptail.io/app/mylightmeter-pro-SOfc/united-states) - [ON1 Photo RAW for Mobile](https://apptail.io/app/on1-photo-raw-for-mobile-Tkgc/united-states) - [Massive Dev Chart Timer](https://apptail.io/app/massive-dev-chart-timer-yyed/united-states) - [Lightme - Logbook](https://apptail.io/app/lightme-logbook-qULd/united-states) - [Manual Flash Calculator](https://apptail.io/app/manual-flash-calculator-idAu/united-states) ## KeyLight PRO Available In - [United States](https://apptail.io/app/keylight-pro-Apzb/united-states) - [Brazil](https://apptail.io/app/keylight-pro-Apzb/brazil) - [United Kingdom](https://apptail.io/app/keylight-pro-Apzb/united-kingdom) - [Chile](https://apptail.io/app/keylight-pro-Apzb/chile) - [Singapore](https://apptail.io/app/keylight-pro-Apzb/singapore) - [India](https://apptail.io/app/keylight-pro-Apzb/india) - [Switzerland](https://apptail.io/app/keylight-pro-Apzb/switzerland) - [China](https://apptail.io/app/keylight-pro-Apzb/china) - [Colombia](https://apptail.io/app/keylight-pro-Apzb/colombia) - [Dominican Republic](https://apptail.io/app/keylight-pro-Apzb/dominican-republic) - [Algeria](https://apptail.io/app/keylight-pro-Apzb/algeria) - [Ecuador](https://apptail.io/app/keylight-pro-Apzb/ecuador) - [Egypt](https://apptail.io/app/keylight-pro-Apzb/egypt) - [Hong Kong SAR China](https://apptail.io/app/keylight-pro-Apzb/hong-kong) - [Israel](https://apptail.io/app/keylight-pro-Apzb/israel) - [Japan](https://apptail.io/app/keylight-pro-Apzb/japan) - [South Korea](https://apptail.io/app/keylight-pro-Apzb/south-korea) - [Kuwait](https://apptail.io/app/keylight-pro-Apzb/kuwait) - [Kazakhstan](https://apptail.io/app/keylight-pro-Apzb/kazakhstan) - [Lebanon](https://apptail.io/app/keylight-pro-Apzb/lebanon) - [Mexico](https://apptail.io/app/keylight-pro-Apzb/mexico) - [Malaysia](https://apptail.io/app/keylight-pro-Apzb/malaysia) - [Nigeria](https://apptail.io/app/keylight-pro-Apzb/nigeria) - [Norway](https://apptail.io/app/keylight-pro-Apzb/norway) - [New Zealand](https://apptail.io/app/keylight-pro-Apzb/new-zealand) - [Peru](https://apptail.io/app/keylight-pro-Apzb/peru) - [Philippines](https://apptail.io/app/keylight-pro-Apzb/philippines) - [Pakistan](https://apptail.io/app/keylight-pro-Apzb/pakistan) - [Russia](https://apptail.io/app/keylight-pro-Apzb/russia) - [Saudi Arabia](https://apptail.io/app/keylight-pro-Apzb/saudi-arabia) - [Thailand](https://apptail.io/app/keylight-pro-Apzb/thailand) - [Türkiye](https://apptail.io/app/keylight-pro-Apzb/turkey) - [Taiwan](https://apptail.io/app/keylight-pro-Apzb/taiwan) - [Ukraine](https://apptail.io/app/keylight-pro-Apzb/ukraine) - [Vietnam](https://apptail.io/app/keylight-pro-Apzb/vietnam) - [United Arab Emirates](https://apptail.io/app/keylight-pro-Apzb/united-arab-emirates) - [South Africa](https://apptail.io/app/keylight-pro-Apzb/south-africa) - [Argentina](https://apptail.io/app/keylight-pro-Apzb/argentina) - [Australia](https://apptail.io/app/keylight-pro-Apzb/australia) - [Azerbaijan](https://apptail.io/app/keylight-pro-Apzb/azerbaijan) - [Belarus](https://apptail.io/app/keylight-pro-Apzb/belarus) - [Canada](https://apptail.io/app/keylight-pro-Apzb/canada) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
