The Nikon D90, a landmark DSLR in its time, introduced many photographers to the convenience and versatility of Live View. This feature, activated primarily through a dedicated "LV" button (though also accessible via a switch on some models), fundamentally changed how users could compose and capture images. This article will delve into the intricacies of the Nikon D90's LV button, exploring its functionality, troubleshooting common issues, and offering a broader perspective on Live View within the context of the D90's overall design and legacy.
How to Use Live View on Your Nikon D90:
The Nikon D90's Live View functionality is relatively straightforward, but understanding its nuances is key to maximizing its potential. The primary method for activating Live View is by pressing the dedicated "LV" button located on the rear of the camera, typically near the shutter release button and other key controls. Once pressed, the camera's optical viewfinder will black out, and the image from the sensor will be displayed on the LCD screen.
This live feed allows you to compose your shot precisely on the screen, offering several advantages:
* Unusual Angles: Shooting from awkward positions, such as low to the ground or high overhead, becomes significantly easier. The LCD screen provides a clear view, eliminating the need to contort your body to use the optical viewfinder.
* Macro Photography: Live View is invaluable for macro photography. The ability to precisely focus on tiny subjects using the LCD screen's magnification feature makes achieving sharp focus significantly easier.
* Video Recording: While the D90's video capabilities are relatively basic by today's standards, the LV mode is essential for initiating video recording. The process typically involves activating Live View and then pressing the shutter button to begin recording.
* Manual Focusing: Live View facilitates precise manual focusing. The ability to magnify the image on the LCD screen allows for critical sharpness assessment, especially beneficial in low-light situations or when using older lenses lacking autofocus capabilities.
However, it's crucial to understand the limitations:
* Speed and Responsiveness: Live View on the D90, compared to modern cameras, is slower. The autofocus system may be less responsive, and there can be a noticeable lag between movements and the display updating.
* Battery Drain: Using Live View consumes more battery power than shooting through the optical viewfinder. It's advisable to keep a spare battery pack on hand, especially during extended shooting sessions using Live View.
* Heat Generation: Prolonged use of Live View can lead to increased heat generation within the camera body. This can, in rare cases, affect performance and potentially shorten the lifespan of components.
Nikon D90 Review and the Significance of Live View:
The Nikon D90, released in 2008, was a significant advancement in consumer-level DSLRs. Its inclusion of HD video recording, coupled with Live View, set it apart from its predecessors. Reviews at the time lauded its image quality, performance, and the innovative addition of these features. The LV button, while seemingly a small detail, played a crucial role in the D90's success, making it appealing to both seasoned photographers and those new to the DSLR world. Live View opened up creative possibilities that were previously limited by the constraints of the optical viewfinder.
The D90's Live View, however, wasn't without its flaws. The aforementioned speed and responsiveness issues, along with the increased battery drain, were frequently mentioned in reviews. Despite these shortcomings, the overall positive impact of Live View on the user experience was undeniable, solidifying its place as a significant feature in future Nikon models.
