In this episode of our series on the Basics of Photography, we’re going to talk about a topic that isn’t very popular, but that almost every photographer has to deal with from time to time: noise. Or, more specifically, image noise of the kind that appears in digital photographs under certain circumstances. In this article, we’re going to look at the different kinds of digital image noise, the specific circumstances under which it appears, and how to get rid of it without compromising the overall quality of the final image.
Back around late last year, we took a very early look at the Zeiss 50mm f2.8 Macro Touit lens for Sony E mount and Fujifilm X mount cameras. We’re happy to say that the new 50mm f2.8 Touit lens is right now in the house and we’re currently underway with testing it. As the company’s third offering for the lens mounts and their first macro lens, it is also the company’s longest focal length. Rendering a 75mm field of view due to the APS-C sized sensors, the lens can double as a portrait optic as well as be used by anyone that just wants some glorious bokeh due to the way that the field of view and aperture work out.
With a full frame equivalent of f4.5 on a full frame camera, this lens is also by all means not small–but nor is it small on image quality.
Phase One’s IQ250 is a medium format back meant for the very high end shooter. At 50MP and not being a full frame 645 chip (it is cropped) you get the change over from CCD to CMOS with the smaller overall size as a tradeoff. Additionally, the back packs in Wifi transmission, a touch screen, great build quality, and some of the best RAW files that we’ve tested.
But interestingly enough, the Phase One IQ250′s biggest flaws have nothing to do with any of these or even the product itself.
When it comes to ultra wide angle lenses, Rokinon has always offered great image quality at an affordable price. They recently announced their 10mm f2.8 for APS-C DSLRs from our usage, we think that it is a pretty decent option for architectural and landscape shooters. The lens has a better build quality than previous offerings and can also deliver some spectacular images.
When the Phase One IQ250 was announced, it was expected to outdo every DSLR in terms of image quality out there because of the large CMOS sensor. But when you get to the medium format level, you’re only as good as the body and the lenses. The IQ250 can output great images; but it isn’t without its drawbacks.
Or at least that what we’re finding so far…
Often our photography has a lot going for it. Sometimes it lacks a clear identity. Before we display our images, we get them critiqued. The first person who critiques your work should be you yourself. As photographers, we spend a lot of time and money wondering if our images are good. We spend time creating and editing the images. We spend money making sure we store the images correctly. We are all susceptible to flattery and we accept when people tell us our images are nice. With our own image though, we must be brutal and unforgiving.
The question is, just how do you do this? Here some tips to help.
