NOISE – ISO PERFORMANCE
Brian Tobey
So where does diffraction begin to impact the D800? Well first we need to know the pixel size. This can be approximated by dividing the sensor size by the number of pixels on a per axis basis.
THE MATH
According to these theoretical approximations, we conclude that ideally we would want to shoot the D800 at f/8 or below in order to prevent diffraction from softening pictures. However, the calculation is flawed in that in accounts for only a single frequency. In our case, we selected 500nm wavelength, which is the color green, the most sensitive to our eyes, to replicate daylight. However, daylight has many colors or frequencies and therefore we must consider the entire bandwidth. This calculation becomes more complicated, but when analyzed across a bandwidth, diffraction becomes more forgiving, which means we can shoot the D800 up to f/11 and be perfectly satisfied with the results!
Note that recently announced Nikon D3200 has an even denser sensor, with 24.2 MP on a DX size sensor. It becomes diffraction limited around f/6.3. This is of more concern than the D800, as most DX lenses are not optimal until f/8. To maximize the quality of the D3200, I’d shoot at f/5.6 and stick with the Nikon 35mm f/1.8G or 50mm f/1.8G. I have always been a fan of those lenses. And if you notice, Nikon shot a lot of the sample images at f/5.6 using some expensive glass.

Ostrost fotografie
Ostrost
Ostrost, to je oč tu běží
U fotografií rozlišujeme dva typy ostrosti. Je jím obrysová ostrost v zásadě jako aplikace neostré masky. Ta vytváří dojem ostrosti tím, že tmavší část v okolí hrany více ztmaví a světlejší část v okolí hrany více zesvětlí. U barevné hrany totéž platí o sytosti hraničních barev. To způsobuje efekt, kdy jsou obrysy ostré a prostor mezi nimi neostrý, často bez kresby.
Druhý typ ostrosti, ten důležitý, je kontrast detailů. Vytváří ostrost fotografie jako celku a zásadně ji ovlivňuje právě objektiv, který musí přenést detaily a senzor a ten je musí zaznamenat. Bodový zdroj světla se zobrazí vždy jako ploška. Když je dostatečně malá, naše oko ji nevnímá a je vše ostré. Čím menší je senzor, respektive obraz na senzoru, tím více se musí zvětšit a plošku už vnímáte jako neostrost. Detaily jsou pak méně patrné.
Pokud přejdete z kompaktu k pokročilejšímu přístroji, nastavte si vyhovující parametry záznamu JPEG snímků ve fotoaparátu nebo při následném převodu z RAW souborů v konvertoru. Výchozí nastavení bývá spíš konzervativní s nižšími hodnotami ostrosti, kontrastu a saturace. Camera RAW, kterou používám, obsahuje původní implicitní nastavení parametrů převodu pro každý podporovaný model fotoaparátu. To ovšem neznamená, že to jsou „správné“ hodnoty, ale pouze jedny z možných pro interpretaci RAW dat.

Jak na zaostření neostrých a rozmazaných fotografií
Každému fotografovi se už jistě podařilo zkazit fotografii rozmazáním – ať už pohybem fotoaparátu při expozici, nebo nesprávným zaostřením. V takové situaci ani programy jako Photoshop nepomohou a při sledování různých kriminálek si většina z nás ťuká na čelo. Naštěstí najdete na internetu pár užitečných prográmků, často děl nadšenců, které opravdu pomohou takové chyby zkorigovat... více

Lightroom 5 or older do not have built-in merge HDR. But you can merge to 32-bit HDR in Photoshop, save it as TIFF and open it in Lightroom. The rest are exactly the same as using Lightroom 6 or above.
Once you have opened Photoshop, go to File > Automate > Merge to HDR Pro. Browse and select the images you want to merge and click ok.
Remember to check the box for Remove Ghosts and select the Mode to 32-bit.
Click OK and don’t make any adjustments. Go to File > Save As and make sure the format is TIFF. Import the TIFF file into Lightroom and continue editing as before.
