تصوير بلا حدود…كيف غيّرت الهواتف الذكية مفهوم الكاميرا؟

كتبت ميرنا أشرف

 التكنولوجيا اصبحت تتسارع عبر الزمن وتسبقه بخطوة حيث انها أصبحت تلعب دورًا مهماً في إعادة تشكيل عالم التصوير، فلم تعد الهواتف الذكية مجرد أدوات للتواصل الاجتماعي فقط يل تحولت إلى منصات تصوير متطورة تنافس الكاميرات الاحترافية في العديد من الجوانب.

 أكد الأستاذ مجدي إبراهيم، رئيس قسم التصوير وشعبة المصورين الصحفيين، أن دخول التكنولوجيا الحديثة في الهواتف الذكية له تأثير كبيرا جدا ومهم وشكل عامل ضغط كبير على الكاميرات لكن التكنولوجيا اثرت ايضا وطورت الكاميرات الاحترافية بشكل متسارع.

 أوضح إبراهيم، أن إدخال الذكاء الاصطناعي (AI) في الكاميرات الاحترافية، فإننا نشهد تحولات كبيرة في جودة التصوير. لكنه أضاف أيضًا أن الهواتف الذكية تتقدم بخطى سريعة جدًا، حيث اصبح بإمكانها تقديم صور ومقاطع فيديو بجودة فائقة، مدعومة بتقنيات الذكاء الاصطناعي، ومعالجة الصور المتقدمة، ومستشعرات أكثر تطورًا

 هواتف بكاميرات احترافية

 بينما يري الأستاذ أمير أيمن، مصور محترف، الي أن الهواتف الذكية في وقتنا هذا تأتي بكاميرات قوية يوجد بها مستشعرات كبيرة وعدسات متنوعة (واسعة، تيليفوتو، ماكرو)، فأصبح من السهل تصوير أي شيء بجودة عالية بدون الاحتياج لكاميرا احترافية.

 أضاف أيمن، أن الذكاء الاصطناعي أصبح يفعل كل شيء بسهولة مثلاً : الهاتف يحلل الصورة ويعدل الألوان والإضاءة تلقائيًا لكي تصبح بأفضل شكل، حتى في الليل أو الإضاءة الضعيفة، ميزة العزل في صور البورتريه وتحسين الصور تلقائيًا اصبحت تنافس الكاميرات الاحترافية.

 اتفقا الطرفان علي، أن المستقبل قد يشهد استخدام الهواتف الذكية في تصوير البرامج لتلفزيونية والمسلسلات والأفلام السينمائية، حيث أصبح التطور الكبير لهذه الأجهزة يمكنها من التنافس مع الكاميرات الاحترافية، خاصة مع تحسينات البرمجيات وتقنيات التصوير التي تعالج الصور بشكل فوري وتعزز الجودة بطريقة لا يمكن للكاميرات التقليدية مجاراتها بسهولة .

 يري الطرفان، أن الهواتف الذكية لن تحل محل الكاميرات الاحترافية بشكل كامل، ولكن يمكن أن تتوسع مجالات استخدامها لتشمل مجالات كانت في السابق مقتصره على المعدات لسينمائية المتخصصة. فمن خلال تحسينات مثل التصوير بتقنية HDR ، ومستشعرات الليزر للتركيز التلقائي، والقدرة على التصوير في ظروف إضاءة منخفضة، أصبحت الهواتف تقدم حلولًا عملية وسريعة يمكن الاعتماد عليها في العديد من الاستخدامات الاحترافية، مما قد جعلها الخيار الأول للعديد من المصورين وصناع المحتوى في المستقبل القريب .

 كل هذه العوامل جعلت التصوير بالهواتف الذكية يتفوق في كثير من الجوانب، حيث أصبح جمع بين الجودة والسرعة في الإنتاج، وسهولة التعديل، والإمكانيات المتطورة، مما يفتح لمجال أمام المزيد من الابتكار والإبداع في عالم التصوير.

 امثلة عن افلام وجمل اعلانية تم تصويرها بالموبايل :   

 Apple – “Shot on iPhone” Campaign .1

حملة إعلانية ضخمة أطلقتها آبل، تضمنت مقاطع فيديو وصور مذهلة تم تصويرها بالكامل باستخدام آيفون، وأثبتت أن الهاتف قادر على إنتاج محتوى احترافي.

 Samsung Galaxy S21 Ultra – “Filmed #withGalaxy” .2

حملة إعلانية عالمية استخدمت هواتف سامسونج لإبراز إمكانيات الكاميرا، خاصة في لتصوير الليلي واللقطات البطيئة .
