One of the main reasons for buying the Nikon D7000 and semi-retiring the D200 was the massive advances made in noise control at high ISO settings. Whilst this camera is not in the same league as the FX (Full Frame) Nikons (D700, D3x etc), the D7000 does a pretty damn spiffing job. I wanted to see if ISO 25,600 on the Nikon D7000 could produce a useable image, or whether it was just there for show. I can confirm that, with a little work this photographer is pleased. This test is only concerned with producing images for web use – your mileage may well differ if you need to make some large prints.
The first shot is straight off the camera – just re-sized and cropped. The noise is clearly noticeable but at such a high ISO on a cropped sensor I still find this remarkable. The D200 doesn’t look this clean at ISO 1,600.
Whilst the results are already pretty spectacular in my opinion, I wanted to see how well Topaz DeNoise would cope with the image. The image below is the result of applying the standard preset ‘JPG Large Grain Severe Noise’ and telling the software to recover details. I then made a couple of colour tweaks in Photoshop CS3.
Whilst you will always lose some details with this aggressive level of noise reduction, I still think Domino looks pretty good. Good enough to make my blog anyway.
The Common Field Grasshopper is one of the most frequently seen grasshoppers in England, along side the Mottled, the Common Green and the Meadow Grasshopper. It is sometimes mistaken for a cricket although a cricket has quite long antennae and the Common Field Grasshopper has relatively short antennae.
Sehirus bicolor. This distinctive little 7mm long shield bug feeds on White dead nettle. The female lays her eggs in the ground and tends to them and the hatched nymphs until they are feeding for themselves. This caring behaviour is not all that common among insects.
Shieldbugs are named after their heraldic shield-like shape and belong to the order Hemiptera. They frequent most types of vegetation and whilst some species are carnivorous, most feed on foliage and berries etc. Shieldbugs go through several stages of growth called nymphs, which are as frequently found as the adults.
Chuffed to bits to find this in the garden
Not a great deal to say on this one… A spider on its web.
Twenty six fisheye images stuck together for this one… Otham Church, just up the road from me. The tower of Otham church is in an unusual position – in the south-east corner of the nave. In fact the church is altogether an unusual shape with a nave and chancel of equal length, both cells having a north chapel. Pretty little church.
