Nikon D610 vs D7100: which camera should you buy? Oct 8th 2013, 23:01, by jmeyer Nikon has announced the Nikon D610, an upgrade to the ‘entry-level full frame’ D600, with improved continuous shooting speeds and other enhancements. This makes it an even stronger rival to the cheaper, DX-format D7100, so how do you choose between them? Our D610 vs D7100 comparison will help! The D600 was Nikon’s cheapest full-frame D-SLR, which made it a strong rival to the company’s top DX-format cameras, particularly the D7100. But reports of sensor dust and oil issues have dented the D600′s appeal for many, so the announcement of the D610 is timely. It also re-opens the FX versus DX debate. The D610 offers full-frame images, but the D7100 offers the same resolution, it's cheaper and it means DX owners can keep using their existing lenses. Nikon D610 vs D7100: 1) Resolution Both cameras have 24-megapixel sensors. The D610 has a full-frame sensor, and the larger size (roughly twice that of the D7100) should give it an inherent quality advantage. But the D7100 dispenses with the usual anti-aliasing filter (just like the ground-breaking Nikon D800E) to provide super-fine sharp detail. Our lab tests reveal that in a Nikon D7100 vs D600 comparison the were neck and neck for JPEGs, both resolving 2800 line widths/picture height, but the D600 edged ahead with RAW files converted into TIFFs, going up to 3000 line widths/picture height. We haven’t been able to test the new D610 yet, but the sensor is unchanged so we’d expect the same result. Nikon D610 vs D7100: 2) Sensor size It's not just about megapixels and resolution. The larger sensor in the D610 will produce images with less overall depth of field and, often, a greater feeling of depth and space. It's easier to get shallow depth of field effects with a full-frame DSLR, though this can backfire if you want to shoot landscapes or still life shots where everything in the frame is sharp, from near to far. A full-frame camera gives you a reduction in depth of field roughly equivalent to 1 f-stop – it's neither good nor bad, but something to be aware of. Nikon D610 vs D7100: 3) Lenses part 1 If you have a selection of DX lenses, you'll have to ditch them when you move up to the D610. You can use them in 'crop' mode, but then you'll be wasting most of the D610's potential. This means buying the Nikon D610 itself will only be the start – there will be plenty more expense to come. With the Nikon D7100, of course, your existing lenses will be just fine. Nikon D610 vs D7100: 4) Lenses part 2 The 1.5x crop factor of the Nikon D7100 means that your telephoto lenses will have a longer reach. This could be especially important for sports and wildlife photographers. Fast, professional-quality telephotos become exponentially more expensive as the focal length increases, and here's a comparison that makes the point plainly. On the D7100, Nikon's 70-200mm f/2.8 telephoto zoom offers an effective focal range of 105-300mm, and it costs £1600. To get the same focal length and maximum aperture on the Nikon D610, you'd need the Nikon 300mm f/2.8 prime lens, which is a whopping £4000. That's not all. The Nikon D7100's new 1.3 'crop' mode, which still delivers 16-megapixel images (the same as the older D7000), gives your telephotos more reach still. The 70-200mm f/2.8 we used as an example earlier now effectively becomes a 136.5-390mm f/2.8! The Nikon 400mm f/2.8 lens, the nearest equivalent for the Nikon D610, costs £6600.

Photoshop depth of field effects: how to make an f/22 exposure look like f/1.2 Oct 8th 2013, 10:30, by jmeyer In this tutorial we’ll show you a really easy way to use simple Photoshop effects to create a sense of shallow depth of field in any image. Shooting with an open aperture creates that lovely shallow depth of field focusing the eye on a subject while blurring out its contextual setting. But while automated modes or simpler cameras, such as mobile phones, may not provide the luxury of aperture control, a little understanding of Photoshop's Layer Masks allows even the longest f/22 exposure to look like it was taken at f/1.2. Masks provide a non-destructive method allowing selective layer visibility depending on the mask content. Create a mask using the Add Layer Mask icon at the foot of the Layers Panel. This becomes visible in the Layers Panel, linked and filled with white by default. Click to select it and paint or fill any areas with black to hide, or mask, areas from view. This simple method allows us to duplicate and blur our image and simply paint into the scene the focused areas to complete our finished effect. How to create shallow depth of field in Photoshop 01 Duplicate and blur Duplicate your original image layer and blur the copy using the Filter>Gaussian Blur. The amount of blur you apply will depend on the content and composition of your image.   02 Create the mask With your blurred layer selected, click the Add a Mask button at the base of the Layers Panel. Your mask appears as a white box next to your layer thumbnail. Click to select it.   03 Reveal sharp areas Make use of the Brush tool as well as Photoshop's various other selection and fill tools to paint black onto the mask to reveal sharp areas from the lower Background layer.

A successor to the popular ‘entry-level full frame’ Nikon D600, the Nikon D610 release date is set for 18 October 2013. The 24.3-megapixel Nikon D610 boasts several key improvements over the Nikon D600. Firstly, continuous shooting speeds have increased to 6 frames per second on the Nikon D610 in both FX and DX formats – up from 5.5fps on the D600. A new Quiet Release burst mode on the Nikon D610 reduces the sound of the camera’s mirror return mechanism, allowing photographers to shoot in ‘near-silence’ at up to 3fps. The new Nikon D610 also inherits the Nikon D4′s Multi-CAM 4800 39-point autofocus system. Compatible with lenses up to f/8 combined open aperture, and sensitive down to -2 EV (ISO 100, 20 °C/68 °F), Nikon says the D610′s AF system achieves sharp images even ‘under moonlight’. Coverage is individually selectable or configurable 9-, 21-, and 39-point settings, and AF modes such as dynamic-area AF and 3D-tracking maintain focus on small subjects, Nikon says. The Nikon D610 also uses the same EXPEED 3 image processor as the D4. Other features on the Nikon D610 spec sheet include Nikon’s Advanced Scene Recognition, which incorporates a 2,016-pixel RGB metering sensor that analyses each scene to detect human faces and colours to support more accurate autofocus and exposure results. Other features include full HD movies in 30p, 25p and 24p, with 60p, 50p and 25p options at 720p; Nikon’s Creative Lighting System to support i-TTL Speedlight flash units and a range of in-camera creative tools. The Nikon D610 price tag will be £1799.99/US$1999.95 body-only or £2299.99/US$2599.99 with the 24-85mm lens.
