Hi, new but been with you forever, & am sure this has been answered before... I'll be teaching an IPhone Camera Course soon, so I shd know this! Need your help - I'm from the film days, made the trans to digital, trying to come to terms with phone photo. Need to know how to explain/understand the difference of quality. I am a purist by heart but sometimes you have to go with technology, I'm trying,. Some say they are very close & that it's not the "tool" it's the user. I have taken several courses on iPhone Photography & am amazed at the controls that are available. I'll stop now and ask for any advice or views. thx in advance

Hi Gail
Welcome to the land of people with nothing better to do than harass others asking questions. I see you've met the crew and have gone through the hazing.

I would say that using the word quality is probably not the correct one.
IMO it would be the difference in application.
The modern day phone camera and associated software has come a long way and can produce some impressive results, as long as the photo taken falls within the optimum parameters of the equipment.

The sensors in phones have improved significantly. They have also improved significantly in DSLR's
We can assume that the sensor quality of the cell phone is on par with most consumer DSLR's. They're just smaller. As you know the size of the sensor will determine the amount of photocells available and the sensitivity of them. The larger the sensor, the more light available. The result is that the DSLR will be able to use the extra light available in darker situations and also allow for faster, action stopping shutter speeds when brighter.

With the format difference comes a variety of lens options.
Yes, there are add on lenses for cell phones that work quite well and provide additional options. There are even more options available to DSLR's, because they don't have to fit in a pocket.
Most will probably agree that the lens is the most significant piece of any setup.
You can capture the highest details of any subject from a fly eye to some planets with the right lens. Those scenario's simply are not available nor were they intended on the phone.

During a recent sunset in a tourist area, I had my tripod with Mirrorless/Dslr camera. A few others had their dedicated cameras, and dozens of others were taking pics with their cell phones. I think I can confidently say that the area below the sunset including the horizon was dark for most. Using the DSLR allows for bracketed photos with spot metering. The resulting HDR photo showing all details would not be matched with the cell. Long exposure night shots repeat the story.

These are examples of application.
Do modern cell phones take great pics? The answer is yes during the right scenarios. Sometimes even competing with DSLR results under print with a good user.

Many other times, not even close.
Good Luck with your class. I hope it results in making more people interested in photography.

Gail, I am shocked & very disappointed by the haughty & disrespectful manner in which you and your perfectly reasonable questions have been greeted here.

Your service to our country, your credentials, and the fact you are a lady entitle you to better than you have received here.

This 69 yo white male with 34 years of service to the same country you have served is ashamed at the way you've been treated.


Yes, the thread got off to a negative start, but there have been some outstanding comments I hope will be of use.

Sorry that some are so “ruffled”.. Anyway, my wife does the scrapbook for a women club and they all submit photos (cell phone pix). Beyond a 4x6, 98% are terrible. Besides shaky, the quality just isn’t there. There ain’t enuff shop in photoshop to fix blurry images and quickie group shots. I keep a canon S100 in each car and manage to smuggle a few pix from it into the pile from every important event she/we attend. With no photo credits, nobody is wiser. And nobody gets hurt feelings.

Hi, Gail! Welcome to the forum.

You did not mention the length or content of your course or anything about the level of knowledge of your students. For the purpose of your question and this post, I'll assume the students are not advanced photographers and will expect a basic course in maximizing the use and results with their cell phone cameras.

I'll preface my suggestions with a brief overview of this and many other photo forums. There are many talented, knowledgeable, helpful, and enthusiastic photographers that contribute to these forums and much of there participation is helpful and well-meaning.Some, however, are so busy and preoccupied with expensive, equipment, "big" lenses, and trying to define their "art" , . their philosophy as to whether the are purists or whatever, or their pining for the "good old film days", that seems that they have no energy left just go out and have fun TAKING PICTURES! Sometimes the snobbery and accompanying worry and arguments take the fun out of the hobby, and even for advanced workers and professionals. You might start off your course by explaining this attitude to your students so they don't begin their adventures into photography with an inferiority complex about their equipment and feel defeated before they start for lack of more sophisticated gear.

Don't dwell on the olden days of film- we are in the digital age of image-making and the iPhones, Smartphones or cell phones are wonderful devices to get folks interested in better picture-making. Folks who did film photography or more advanced work in the past can certainly apply what the already know and any artistic principles to modern digital photography. The thing I love about cellphone cameras is they are accessible and turns a lot of folks onto photography that perhaps have never experienced the fun, joy, and satisfaction of image-making.

Alright, so an iPhone is NOT a complex system camera with all kinds of interchangeable lenses and accessories but let's see what it can do. This should be part of your teaching approach.

The first segment of your course should be to simply familiarize everyone with the BASIC operation of their device as to using it in both automatic and manual modes. Each person should examine the features of their individual device and know how to access them. If the phone has any built-in special effects, filters, zoom, feature or can simulate the effects of a telephoto, fisheye lens, shoot in monochrome or sepia, selective focus, video options, etc. each student should be aware of these options if they are built-in to there devices. Some devices can do selective focus, high-speed action capture, and other effects.

A basic primer in manual mode can follow, if there is enough time, especially if the course is spread over several sessions. The principles and functions of aperture, shutter speed ISO settings, white balance, focus, and focal length change should be explained.

Emphases should be placed on the aesthetic and artistic possibilities as to composition, and the use of light. Even with the device in point-and-shoot mode, exceptionally and surprisingly nice images can be derived when the photographer employees good aesthetics. Many of these devices have a "grid" that assists in teaching and learning the rule of thirds and other basic elements of composition. Each stude shod SET UP their camera for convenient operation as to things like using some of the control buttons as a shutter release, enabling auto-rotate. etc.

Suggest projects such as making portraits of families, children loved ones, pets, etc. Talks about landscapes, vacation shots, photograhy their other hobbies, cars, visits to museums and points of interest when touring, etc. Most of this device can focus in surprisingly close and great images of flowers and other detailed small subjects are possible. Interesting still life images can be made with simple window light.

Folks keep their devices in there pockets so talk about keeping the lens and screen clean and adjusting the screen brightness to accommodate ambient light.

Next! Introduce them to POST-PROCESSING. There are a plethora of incredible apps whereby they can crop. sharpen, adjust, and add special effects to any of their images. I will recommend Snapseed, Tool-Wiz Photo, and Prisma. Theses are like carrying a "darkroom" in your pocket. You can dodge, burn, color correct, sharpen, diffuse, retouch, add textures and all kinds of fun special effects. Theses apps offer free downloads. There are also lite versions of PhotoShop and Lightroom!

Don't ddwell on the limitations or what a cellphone camera CAN"T do but emphasize what it CAN do!

This is a great introduction to digital imaging. Some folks will just become better snapshooters and others may venture into more advanced gear and techniques if the so-called bug bites them.

Start off with "nuts and bolts" instruction- simply how to operate the device. once the know wah they are doing, the artistic, creative and fun aspects can be introduced.

I am a full-time commercial photographer wit over 50 years in the business. I have all kinds of heavy gear- the operative word being "heavy" and I can't take it wherever I go a just want to have fun and so some casual spontaneous shooting. I even take my device assignments to record setups for teaching and training, scouting locations, and transmitting rough ideas and concepts to clients and art directors while I am out on location.

A few weeks ago, we took a day off to make a family visit to the countryside and stopped at a picturesque village and a museum site. The attached images were made with my Samsung Galaxy.

Teach by example. Thats where the truth lives. Actual real world examples. Examples of all kinds of lighting, color and dynamic range. Make prints, enlarge, display on various displays. Push some processing lattitudes. A picture is worth a thousand words, easily. The students themselves will see, as you do. What ya see is what ya get. How ya get what ya see follows. Otherwise, what are you really "teaching"?

Do you know WHY those images won’t go up to larger sizes?

It’s because email programs, social media sites, and text messaging software all tend to downsample the phone images to smaller pixel dimensions, and then compress them heavily, by default.

If you know what you’re doing, you can override default settings and send original images.

I do, but the ladies sending probably don’t. Am at the mercy of the sources. My only point was- regarding the original question - was: essentially camera beats cell phone every time.

I shoot with both. But use my DSLR for most photography. Way more options, control,lenses. Love my phone for when there's a picture I want and that's all I have.

In any smartphone the dimensions of the phone real estate places limits on lens and sensor dimensions and their spacing. How thick is the phone. After deducting the thickness of tbe screen and circuit board, how far apart can the lens and sensor can be. For the lens, how big is the hole for it - that places a lower limit on the radius of curvature and defines one end of the focal length achievable. All of this will define an angular cone of some base radius which defines the sensor size. I have looked around for iPhone 8+ design specs without success so can’t get specific.

Burk, what do you suggest to get the native smartphone image out into a computer. My iPhone 8+ does not have a SSD chip. Also, Photoshop alternatives.

I don't have an iPhone but do have a Samsung Galaxy S5 (rather old by today's standards). I never printed any of the photos on my phone because I just assumed anything above 4 x 6 or 5 x 7 would not look good. Recently, I had a need to print an 8 x 12 picture I had on my phone. Again, I assumed it would not look very good. I was surprised. It looked as about as good as 8 x 12s from my Canon 60D (also old by today's standards). I assume that the cameras on today's iPhone or Galaxy are lots better than mine and should produce better pictures. I liked the suggestion to take the best picture you can with your phone and make several prints of various sizes to see how big the phone camera can take you and still look good. If I were teaching a course, I would have my students use their phones to take a variety of pictures under different conditions, make prints of various sizes and see what, if any, limitations there are on phone photography. Do the same with a point and shoot and a DSLR camera and compare the results.
