How Many Mp For A Good Camera
Each year camera manufacturers are pushing the limits of sensor engineering and the latest tendency has been to increase sensor resolution to numbers that were considered unfathomable before. With full-frame cameras reaching 60 megapixels (MP) and medium format cameras pushing beyond 100 MP, we now know that the megapixel race won't stop at that place and we will most probable be seeing cameras with even more resolution in the hereafter. But the big question remains – how much resolution does one truly need today? Is 12 MP too petty? Is 50 MP too much? While it is a subject that tin exist open to countless debates, I have been working on a methodology to determine the ideal megapixel range for one's needs. In this commodity, I will share what I came up with and information technology volition hopefully serve every bit a good guide for our readers in deciding how to address the megapixel quench. I highly recommend you read our camera resolution explained commodity as a pre-requisite to sympathise the relationship of resolution to printing, cropping, display size and to understand such terms every bit downwardly-sampling in more item. You may also desire to read almost how to increase the resolution of an image.
Nearly of united states of america get caught in deciding over what resolution to cull in the early days of shopping for our commencement camera. There are so many options to choose from. And just like buying our offset car or the first dwelling, we want to get the best camera for our all the same undetermined and mostly unknown needs. We actually don't know if we are going to be serious photographers, or the camera will be sitting on a shelf and collecting dust until nosotros take it on a vacation. Considering of this, it usually makes little sense to purchase the most capable camera on the market as the first photographic camera, only like information technology makes little sense to buy a Ferrari as the first motorcar, or a million dollar home equally the first home. You want to offset out with something smaller, something less expensive and something you can grow with.
And when the demand arises to move up to something more capable, you will know exactly what to get. I always advise to go an entry-level camera showtime, and then eventually motion up to something more serious in a few years, if there is such a demand. And instead of taking a large leap later, information technology is always a good thought to motion upwardly gradually. You do not want to spring to a full-frame 60 MP photographic camera from a bespeak-and-shoot or an entry-level camera, unless you really know what you are doing.
1) Camera Resolution: Low, Medium or Loftier?
Before we become into the details, let's commencement go over pop camera resolutions to sympathize what represents depression, medium and high resolution by modernistic standards. I will get over Micro Iv Thirds, APS-C and full-frame, since they are the most popular formats available today:
Micro 4 Thirds
- Low Resolution: Upwards to 10 MP
- Medium Resolution: 11-16 MP
- High Resolution: 20+ MP
APS-C
- Low Resolution: Upward to 10 MP
- Medium Resolution: 11-20 MP
- Loftier Resolution: 24+ MP
35mm / Total-Frame
- Depression Resolution: Up to 16 MP
- Medium Resolution: sixteen-24 MP
- Loftier Resolution: 36+ MP
Please notation that the above categorization is done based on boilerplate pixel size, is subjective and can change with advancements in engineering. Sensors with low resolution usually have the largest pixels up to 8.5 µm, with medium resolution ranging between 5.0 µm and viii.0 µm (depending on sensor size) and modernistic loftier resolution sensors more often than not accept much smaller pixels between 3.0 µm to 5.0 µm. Information technology is important to notation that the smaller the pixel, the higher the resolution will exist on the aforementioned size sensor.
Based on the above information, you lot can approximately tell if you are using a low, medium or high resolution camera by today'southward standards.
two) Photographic camera Resolution for Hobbyists
As I take already mentioned in my article on resolution, camera resolution has a direct impact on how large you tin print, how much yous can crop, how big y'all tin can display your images and how much y'all tin down-sample. While all of these can be important, the truth is, very few of us actually print, display size is usually limited to ii-4 MP, cropping and down-sampling can be avoided with skilful technique.
Then if you lot are a hobbyist and just enjoy taking pictures for yourself and your family, a ten-16 MP camera is going to be sufficient to accommodate most of your needs. You lot can make decent size prints, display loftier resolution images on the spider web, have plenty of space for cropping and enough room to downwards-sample as well. 90% of photographers out there simply do not need more resolution – for the most function, more resolution is going to be pretty much a waste matter.
However, this does not mean that high resolution cameras are useless – in that location are situations when high resolution is needed. Allow'south talk about that at present.
3) Loftier Resolution is for Specialized Needs
Once you lot grow as a photographer, yous volition get to the point when you know what type of photography is virtually appealing for you, so you become more specialized. Although some photographers do end up doing a mix of things such as landscapes and wildlife, most choose one particular blazon of photography every bit the chief hobby or money-maker / career. Such photographers will know when they truly need a higher resolution camera and how they tin can accept advantage of such a specialized tool for their photography. If you are wondering whether a higher megapixel camera is something y'all should consider for your photography needs or non, then read on.
4) Types of Photography that tin can Do good from a High Resolution Camera
Some particular types of photography can do good from a high resolution photographic camera. If you find yourself doing whatsoever of the below listed types of photography seriously (equally a serious hobby or a profession), then moving upwards in resolution will almost probable benefit you lot:
- Landscape
- Compages
- Fashion / Studio
- Production / Macro
Mostly, all of the above photography types are in the low ISO range where dynamic range is the highest and there is a minimum corporeality of noise. Besides, such photography frequently requires very large prints and the extra resolution can make a large difference in bringing out equally much detail in prints as possible.
5) Determining Your Working ISO Range
To sympathise if moving up in resolution will truly benefit you lot or non, it is a good thought to come across what your working ISO range is. If you analyze images from your by year or ii, you tin discover out if you lot tend to shoot in low, mid or high ISO range. Finding out your working ISO range is important, because if y'all tend to exist above the low ISO range, then a loftier resolution camera might not be of benefit for you. Both dynamic range and ISO performance tend to autumn off quickly above ISO 400 at pixel level, then you might be putting unnecessary load on your reckoner and storage (meet below), since you are most likely constantly having to down-sample images.
How can you find out what your working ISO range is? There are many ways, merely if you are a Lightroom user, it is actually like shooting fish in a barrel. Merely become to your last year's itemize, or if you lot have a single itemize where y'all shop all of your images, you lot will exist able to utilise the Library Filter to only show images from a selected period. Beginning, we will find out how you shoot overall, then we volition find out your working ISO range for the best images in the catalog.
To bring up the Library Filter, either get to View -> Show Filter Bar, or printing the "\" button on your keyboard. Once the Library Filter shows upward, click on "Metadata" text. From at that place, make sure to select the desired "Date" – I picked 2014 to show me all images from 2014. Pick "All" under "Camera" and "All" under "Lens". The concluding window is unremarkably called "Label", but you tin can change it to a number of different filters. Simply click on the word "Characterization" and a window will popular up that you tin can cull different filters from. Select "ISO Speed" as shown below:
One time you lot practise that, yous will see that the final window will at present show a range of different ISO speeds:
From hither, what you will need to do is compile a table with different ISO ranges by summing up the numbers. Here is what my working range looks like in detail:
- ISO 50-100 : 12291 (38.76%)
- ISO 100-200 : 5746 (xviii.12%)
- ISO 200-400 : 4914 (15.50%)
- ISO 400-800 : 3883 (12.26%)
- ISO 800-1600 : 2402 (7.57%)
- ISO 1600-3200 : 1840 (5.80%)
- ISO 3200-6400 : 559 (1.76%)
- ISO 6400-12800 : 54 (0.17%)
- ISO 12800+ : xviii (0.06%)
- Total Images : 31707
At present this is swell data, because it clearly shows that I strongly prefer working with low ISO range much more mid or high ISO range. Looks like close to 40% of all of my images were captured between ISO 50 and 100 and if I sum upwards all the data from ISO fifty to 400, that'due south 72% of all the photos in the itemize!
Nevertheless, the to a higher place data is for all photographs and information technology does not mean that I used or planned to use all 31K of images. While it is interesting to know my overall shooting blueprint, the more important statistic is how many images I actually flagged with five stars to use. If you click the "Attribute" text, you can likewise pick a rating to filter by. Provided that y'all accept been rating your favorite images with stars, you can click on the stars and the Library Filter will only prove your rated images:
Then here is my updated data:
- ISO l-100 : 2984 (42.62%)
- ISO 100-200 : 1220 (17.42%)
- ISO 200-400 : 1119 (xv.98%)
- ISO 400-800 : 887 (12.66%)
- ISO 800-1600 : 447 (6.38%)
- ISO 1600-3200 : 271 (three.87%)
- ISO 3200-6400 : 58 (0.83%)
- ISO 6400-12800 : 16 (0.23%)
- ISO 12800+ : 1 (0.01%)
- Total Images : 7003
Once more, the in a higher place information shows that well-nigh of my images are captured in the ISO fifty-400 range, with 76% of photos being in low ISO. If information technology was not for indoor portraits and other experiments for camera reviews, the in a higher place stats would have been in a higher place 85% for low ISO.
6) Interpreting the Data
Now that I know what my working ISO range is, what does it mean for me? Since over 75% of my favorite photographs in 2014 were captured between ISO 50 and 400, I can conclude that I could definitely benefit from a loftier resolution sensor. Since such sensors perform best below ISO 800, I can certainly consider moving up to a college megapixel camera.
If I were to have almost of my shots in the mid range from ISO 400 to 1600, so a mid-range camera would be more beneficial for my work. And if I shot a lot in the ISO 1600 to 6400 and higher range, a low-resolution camera would obviously be the most advisable i for my needs.
When you compile your data, look at where yous shoot the most and if the college ISO range represents bigger numbers, you might want to keep shooting with a lower megapixel photographic camera and not worry about upgrading. I bet if I primarily photographed wildlife, my stats above would have looked completely dissimilar…
vii) Lens Re-evaluation
As I take previously stated in my Camera Resolution Explained commodity, lens sharpness and its resolving ability are extremely important in order to take advantage of high resolution sensor cameras. If y'all exercise determine to move upwards in resolution, it is a good idea to re-evaluate your lens stable and meet if your current lenses are good plenty for the task or not. Sometime 35mm lenses designed for movie cameras might be fairly practiced in the center, merely they surely volition endure in the mid-frame and corners, since picture is not flat like imaging sensor and there is no filter stack in front of it like on all digital cameras. Too, keep in heed that the college the resolution, the more stress there will be on your lens' resolving power. A lens might do adequately well on a 24 MP sensor, but might not resolve plenty details at higher resolutions.
To take a full reward of loftier resolution sensors, you lot will most likely need to invest in loftier-end professional person-level lenses that deliver outstanding center to corner performance and have a skillful command of chromatic aberration, field curvature and other lens aberrations. You might also want to await into your existing lenses and make certain that they are not severely decentered, every bit you probably do non want to see inconsistent performance throughout the frame.
I personally had to learn this the difficult way – sure lenses that I loved in the past, such as the Nikkor 24mm f/3.five PC-E did quite poorly on loftier resolution cameras like the Nikon D810, having pretty average sharpness in the center and quite poor performance in the corners, something I did non expect to see.
8) Figurer Hardware Needs
If most of your shots are in the low ISO range and yous are ready to motility up to a higher resolution camera, the side by side surface area to look into is your computer hardware. Is your hardware sufficient to process those huge RAW files? Are you lot running a 64-bit operating arrangement that can take full advantage of your estimator retentivity (RAM)? How fast is your processor?
Many photographers were quite surprised by the fact that their existing computers could no longer properly piece of work with loftier resolution RAW images from cameras like the Nikon D800 – the jump from 12-16 MP to 36 MP was a huge difference. Lightroom got slower than always and opening up and working with RAW files in Photoshop got noticeably slower, especially when working with many layers or when stitching panoramas. To avoid such issues, it is a practiced idea to keep up with your computer hardware and only movement upward to a higher resolution camera if your computer has enough horsepower.
Here is my current PC configuration that I built for myself in 2018:
- Operating System: Windows 10 64-bit
- Monitor: 2x Dell U2413 (old, merely very functional IPS monitors)
- Processor: Intel Core i9-9900K
- Memory / RAM: 64 GB (4x 16GB DDR4)
- Video Carte du jour: NVIDIA Quadro P2000
- Principal Storage (OS): Samsung 512 GB 970 Pro NVMe (SSD)
- Secondary Storage: Samsung 2 TB 860 Pro Serial (SSD)
If you prefer to use a Mac, then here is the configuration I would recommend for an iMac:
- Monitor: Retina 5K
- Processor: Intel Cadre i9
- Retentiveness / RAM: 64 GB
- Video Bill of fare: AMD Radeon Pro 575x
- Hard disk drive: 512 GB Flash Storage
You lot can discover a similarly-built iMac Retina at B&H Photograph Video.
Since Lightroom catalogs can be quite enervating on your difficult disks, it is best to put them on fast SSD or flash retentivity. Ideally, you lot desire to put photos on fast storage likewise, only if high-capacity SSD drives are out of your budget, employ 7200 RPM or faster difficult drives. Since traditional hard drives are more prone to failures than SSD, it might exist a good idea to use 2 hard drives in RAID 1 (Mirror) configuration. Please keep in mind that RAID ane volume should non be used as your backup – always back your information up separately to other external media or storage units like the ioSafe 214 that I have previously reviewed.
Adjacent, we volition talk well-nigh storage needs.
9) Storage Needs
Shooting with a high resolution camera is expensive not only in terms of equipment needs, but too storage. If y'all take older, low capacity hard drives, you might take to upgrade to newer, high chapters difficult drives to store your photos. Not merely does it mean that you might have to re-evaluate your electric current storage in your figurer, but you might also have to look into upgrading your external difficult drives, backup media and other online or offline storage. High resolution cameras similar Nikon D850 can create huge RAW files that are equally large every bit fourscore-120 MB each, depending on bit rate and compression you lot choose in your photographic camera. On average, your files will probably exist around 35-50 MB if you shoot lossless compressed. And if you use Photoshop or third political party software to process your RAW files, expect your resulting TIFF files to counterbalance over 250 MB depending on how many layers of information you are storing. In short, your storage needs will surely increase rather significantly.
The good news is, storage is cheaper than ever, and fast SSD and NVMe flash drives have gotten much more affordable, so information technology is non a major concern. However, if you take been relying on those spinning hard drives for a long time now, y'all might find them to be bereft for high resolution workflow.
Hither are the storage areas you might demand to address:
- Calculator Storage for Lightroom catalog and photos
- External Storage for Backups / Offline photos
- External Storage (NAS, SAN, etc) for Backups / Offline / shared photos
- Online Storage for cloud-based storage
x) Technical Know-How
Last, but not to the lowest degree, is your technical know-how and skill when it comes to shooting with high resolution cameras. You might be used to shooting at slow shutter speeds similar one/twenty-1/100th of a 2nd with your current photographic camera and lens, only in one case you move upward to a camera with a lot more resolution, you might take to bump up your everyman thresholds to much college values. If y'all want tack sharp images at 100% zoom, yous volition discover that loftier resolution cameras can be quite enervating when information technology comes to your paw-belongings and general camera performance/handling techniques. Camera shutter vibrations will be a lot more pronounced and the mirror slap on your DSLR might strength you to use features similar electronic front curtain shutter and exposure delay a lot more than than before. You might find yourself wanting to upgrade to a more stable tripod and tripod caput in order to reduce those slight vibrations.
You might also find your optical viewfinder to be somewhat inadequate for yielding perfectly focused images, forcing you lot to apply live view with zooming features a lot more than you might be comfy with. Unless you move to a mirrorless camera with focus peaking and other focus aid features, shooting with a high resolution camera might get quickly frustrating for this reason alone.
xi) Summary
As you lot can encounter, it is important to explore a number of different areas to find out if yous are ready to move up to a photographic camera with a college resolution. Information technology is also as important to look into your existing work and determine your current and future needs. Will your photography really benefit from a college resolution camera? Are you planning to brand large prints, mail or potentially sell your high resolution images online? Practice you have the noesis and the proper tools to work with high resolution images? These are some of the questions yous should challenge yourself with before considering that next super high resolution body camera manufacturers are luring you into buying…
