Hey orris
Can u help me in edit a photo
- Crop or resize
- Adjust brightness, contrast, or colors
- Add text or watermark
- Remove background
- Filters or effects
So I want you to give the effect of the first pic in the 2nd pic without distrubing the car

- Used GrabCut AI segmentation to isolate the white Hyundai Creta from the parking lot background
- Applied a 200px horizontal motion blur to the background (ceiling, pillars, background cars) - mimicking the panning/tracking shot effect from Pic 1
- The white car stays sharp and untouched
- Subtle edge feathering makes the transition between sharp car and blurred background look natural
- A mild brightness boost on the car makes it pop against the blurred background

Note: For an even cleaner edge around the car (especially the wheels and mirrors), a professional tool like Adobe Photoshop or Lightroom with AI-powered subject selection would give pixel-perfect masking. But this result gives a solid motion-blur panning effect with the car preserved. Let me know if you'd like any adjustments - like stronger/weaker blur, or a different blur direction!
