UNDEREXPOSED FILM
THE Trouble: Your negative was exposed to light for likewise brusque a time to tape a well-defined image on the motion-picture show.
HOW TO RECOGNIZE IT: Your scans volition expect dark/faded, grainy, and have very depression contrast. Your negative film will be very faint/run into-through.
HOW TO Prepare IT: Get yourself a light meter and then you lot tin adjust your camera settings correctly for dissimilar lighting scenarios. You might too want to shoot a test roll to become a meliorate handle on exposure in general. If the underexposure is non too intense, you tin arrange affected frames in a photo editor such equally Lightroom or Photoshop to become "passable" images.
OVEREXPOSED FILM
THE Problem: Your negative was exposed to light for also long, making your negatives too dense.
HOW TO RECOGNIZE IT: The highlights in your scanned images will be slow and grayness—this is considering, in an endeavour to preserve definition throughout the mid-tones, our scanners must reduce the overall lightness of your epitome. Your negatives volition exist very high contrast between the darkest dark and the lightest light, only the dark, dumbo areas dominate throughout.
HOW TO Set It: Grab a low-cal meter to properly estimate lighting, and consider shooting some test rolls. Overexposing color film a couple of stops tin actually be a powerful shooting tool in film photography, simply only if you can understand when and why. If film is non also severely overexposed, some moderate post-production piece of work can be done. It won't exist corking, merely information technology will be tolerable.
Obstruction IN YOUR CAMERA
THE Trouble: Something yucky has wormed its manner into your camera. Mayhap it'due south pilus, maybe it'southward dust, peradventure information technology's an unidentifiable gunk. It can fifty-fifty be the protective paper bankroll on your 120 flick.
HOW TO RECOGNIZE IT: Obstructions in your camera will appear on your picture scans as dark marks, oftentimes actualization on multiple frames in a row.
HOW TO Ready It: Keep your camera as clean as a whistle with regular maintenance at home—clean your camera dorsum and insert with canned air before every shoot. Reoccurring obstructions tin sometimes exist a piece of your camera itself, and should be repaired at a camera store.
Obstruction IN THE FILM SCANNER
THE Problem: Dust and other small particles are clinging to your moving-picture show or the scanning bed.
HOW TO RECOGNIZE It: Obstructions in the scanner will appear on your films scans as tiny white marks or lines.
HOW TO FIX IT: Richard always takes care to prevent this from happening when scanning your film, including brushing & vacuuming your negs and digitally removing noticeable dust and scratches (either with a special automated software or manually). We clean dust, etc. that is visible at an image size of 25-xxx%. If you lot still encounter dust on your scans, please get in impact with the Richard coiffure!
LIGHT LEAKS
THE PROBLEM: Light is getting into your camera. This is commonly due to a faulty back, in which calorie-free-tight seals are damaged or worn.
HOW TO RECOGNIZE IT: Light leaks announced every bit faded or discolored streaks or bursts in a browse—they will extend outside the frame to the rebate edge.
HOW TO Fix IT: Double cheque that the seals on your photographic camera are light tight by shooting another roll of film. If it comes dorsum clean, then it was probably merely a simple user error—if not, have your camera to get checked out past a pro.
FOGGING
THE PROBLEM: Fogging can exist caused by a number of things, including heat harm to your film, aging of film, or accidental exposure to light (like opening your photographic camera mid-roll).
HOW TO RECOGNIZE IT: Fogging is like to a light leak, causing fading & discoloration. All the same, it affects the film surface more evenly overall, whereas a light leak typically emanates from a concentrated spot.
HOW TO FIX IT: Eliminate the variables to detect the root of the problem. Shoot a exam roll with a make spankin' new roll of film—if the curl comes dorsum clear, and so the issue was caused by your original motion picture. If non, head to a camera repair shop.
FLARES
THE Problem: Low-cal is refracting and reflecting within your lens. This happens when your field of study is backlit and you are pointing your camera directly at the sun.
HOW TO RECOGNIZE IT: Flares appear as bright, low contrast, muddy or discolored patches that oftentimes (but not exclusively) develop in the corners of an paradigm.
HOW TO Set up IT: Always exist mindful of your light source to avoid flare, and consider using a lens hood (or your hands!) to block whatever stray low-cal. Sometimes flares tin exist dulled in postal service-production by adjusting the colour balance over the flare—though, some artists love the look of flares in their images!
LOOSE FILM Curl
THE PROBLEM: When shooting medium format 120 or 220 picture show, your film is not tightly rolled after exposure. This tin can happen considering the motion picture was non secured properly (with record or film strip adhesive) and it unraveled, or your camera never rolled the moving-picture show tightly enough to begin with (mutual in disposable cameras).
HOW TO RECOGNIZE Information technology: There is a soft ruby or white line across an entire edge of your scanned frame—also known as "edge fog".
HOW TO FIX Information technology: Make sure your film is tightly sealed after removing it from your camera. If you suspect your photographic camera could be at fault, yous'll need to head to a repair shop to confirm that information technology's winding film correctly. Because damage from a loose gyre typically stays at the border of a frame, some scans with this issue can be saved by doing a little cropping.
CAMERA OPENED MID FILM Whorl
THE PROBLEM: This one is pretty obvious—your photographic camera opened in the heart of shooting your coil. Nosotros're all human being, it happens!
HOW TO RECOGNIZE Information technology: Large blocks of your scan are discolored. This can range from an orange-crimson tint on parts of your prototype to completely bleaching it out. The impairment will cover the frame line and rebate border, but it'south much larger than a regular ol' light leak.
HOW TO Set It: There's not a whole lot y'all can exercise to save an epitome when this happens, typically because the harm covers so much of the frame. On the bright side, later on seeing the results yous'll be actress conscientious information technology doesn't happen again!
CAMERA ADVANCEMENT MALFUNCTION
THE Trouble: Your camera is not moving moving picture through the camera body uniformly (similar it should).
HOW TO RECOGNIZE It: When you look at your negatives, your frames volition either be too far apart (giving y'all less frames on the roll) or they will overlap (resulting in double exposures over a portion of the scan).
HOW TO Fix It: Your photographic camera may demand a checkup from a pro. However, this event tin also occur if your moving picture is loaded or manually avant-garde incorrectly.
TWIN CHECK STICKER
THE PROBLEM: Twin check stickers are applied to your negatives in the dark earlier film processing in lodge to help united states of america track it through the lab; ordinarily, there is non an image frame on this portion of the film. If there is, this is some other sign that at that place is a camera advancement malfunction or film-loading mistake.
HOW TO RECOGNIZE IT: There is a sticker on the terminal frame of your scroll, and a big white rectangle on the corresponding browse.
HOW TO FIX IT: First, double-bank check that you are loading your flick correctly and starting your exposures at the correct place on the scroll. If you are withal seeing issues with advocacy, your camera may need a tune up! Some image frames can be saved with a little post-production magic, depending on the image and how far the sticker imposes on the frame.
SHUTTER SYNC MALFUNCTION
THE Trouble: When yous are using a flash and a camera with a curtain shutter, the "sync speed" is the fastest shutter speed you should apply. If you set a faster shutter speed, the shutter starts closing before your flash has gone off, literally blocking a portion of your frame from existence exposed.
HOW TO RECOGNIZE IT: In that location is a thick, black, uniform line on your prototype that reaches the edge of the frame.
HOW TO Gear up It: Deadening down the shutter, speed demon! Exist wary of sync speed, because at that place is no saving these frames in one case they are exposed.
Photographic camera SCRATCH
THE PROBLEM: Typically, either dust, dirt, or sand accept gotten into the camera insert or photographic camera dorsum, scratching the base side of your movie. This can also occur on the emulsion side of your film due to dirt, nicks, or viscous rollers.
HOW TO RECOGNIZE Information technology: There is a very abrupt, directly line across your scan—it tin can be light or dark. These lines sometimes start and stop in sequence with the exposures. Photographic camera scratches are always the aforementioned direction across your movie frames because of the management that the film travels through your camera. Sometimes, light scratches volition be removed by the automated software Richard uses to remove dust from film scans—in this case, you lot will merely run across the scratch on your negatives.
HOW TO Gear up Information technology: Information technology's time for a DEEEEEEP clean from a professional. The rollers, the insert, everything needs a skillful scrub-a-dub-dub! And be sure you lot're doing basic maintenance on the regular, cleaning your camera with canned air before each shoot. Scratches tin often be removed from scans by doing some post-production work in Photoshop.
HANDLING Damage
THE PROBLEM: Your film negative was damaged when someone at the lab was treatment your motion-picture show or your negatives were stored improperly—this scratching or denting can and so show up in your scans.
HOW TO RECOGNIZE IT: Light colored lines (scratches) or crescents (dents) appear on your scan. They are not geometric or uniform, and they practise not appear the same across multiple frames.
HOW TO FIX IT: At Richard, we take every precaution to prevent harm to your negatives: hiring experienced technicians, using protective gloves and well-maintained equipment, and always sleeving your negatives. When damage does occur, Richard will retouch the damage out of your image files. If you always see handling scratches and crescents on your scans, please contact the lab!
SCAN LINES
THE PROBLEM: At that place is dust or dirt interfering with the film scanning equipment.
HOW TO RECOGNIZE IT: There is a thin, straight line across your scanned image. It can be differentiated from pressure plate scratches past the visible digital noise effectually the line.
HOW TO FIX IT: At Richard, nosotros routinely clean and recalibrate our equipment to foreclose this issue. If y'all call back you see browse lines in your order, please attain out to united states immediately!
THE STAIRCASE EFFECT
THE Problem: Honestly, we aren't exactly sure what causes this issue to occur (though there is speculation that reflections from the film itself during standard operation of the auto could exist the culprit). What we DO know for sure is that scans displaying the staircase upshot come from very overexposed negatives.
HOW TO RECOGNIZE IT: There are soft, evenly-spaced, dark bands overlaying your pic photo image from edge to border.
HOW TO Set up IT: Brand certain you aren't overexposing your negatives! Apply a loftier-quality light meter every time you lot shoot. Some images tin can be altered in post-production to minimize the appearance of banding.
H2o Impairment
THE PROBLEM: Your moving picture got wet from condensation, a spill in your camera pocketbook, an adventitious dip in the pool, etc.
HOW TO RECOGNIZE It: The results can range—we've seen irregular waves through the image, a speckled design, large black splotches, and extreme discoloration. Only the one affair this type of harm e'er has is a distinctly "liquid" wait.
HOW TO FIX It: If yous know you accept gotten your film wet, ship that roll to the lab immediately! Be sure to include a notation about the damage in the "SPECIAL INSTRUCTIONS" portion of the online ordering course. Seal your film in an air-tight bag/container, besides, so it does not dry! This can help lessen the harm. Scans showing water damage are typically beyond saving—simply who knows, maybe you'll end up loving the organically abstruse effects displayed in each unique photo!
X-RAY DAMAGE
THE Trouble: Your moving-picture show has been exposed to a form of electromagnetic radiation. This usually happens when yous travel via plane with your film.
HOW TO RECOGNIZE It: In that location is a big, wavy pattern across your entire roll of negatives.
HOW TO FIX It: Richard wrote an extensive blog mail service on ten-ray damage you will want to read, simply here'south the short & sweet version—never put film in luggage going in the cargo concur of a plane. Opt for a mitt check of your carry-ons instead of using atomic number 82-lined bags, and clearly label packages existence shipped internationally.
