 Resolution for really sharp prints
Introduction The generally accepted figure in the publishing and photographic industry is 300 PPI. It's like a mantra in the imaging world - hi res = 300PPI (usually mis-named as 'DPI'). However, this tells very little of the real story of resolution and image sharpness/quality. It says nothing ...
- Processing Imacon RAW files in 3F format in the FlexColor Virtual Scanner
FlexColor is the scanner software used with Imacon/Hasselblad scanners. One very very nice possibility with this scanner is that it gives you that chance to produce a proper RAW 3F file, and then 'develop' this raw file on a Virtual Scanner in the FlexColor software. This allows you to get t ...
- The Media We Burn Your Scans To
All media used by Image Science is Taiyo Yuden (JVC) media - the best quality CD and DVD archival media available (short of the truly specialist survive-a-nuclear-winter $20 a CD type stuff). If your order fills less than one CD we will burn a CD. There is no charge for this. If your order fi ...
- Why we can't upload your full size scan files
It's all about the 'A' in ADSL. It stands for 'asychronous' and what it means in practise is that we our internet connection offers very fast downloads (in practise we can get up to about 2 MB/s) but very slow uploads (at best about 150kb/s but more typically about 100 kb/s in practise). We're ...
- About Scanning Resolution
Fact Vs Fantasy! Even several years ago, you could buy a so-called 4800 PPI film scanner from various makers like Epson, Canon, Microtek etc, which could handle film sizes from 35mm through to large format. So why doesn't everyone scan on one of those? Because those 'resolution' numbers are she ...
- 8 bit versus 16 bit
One of the questions we most often receive results from confusion about the bit-depth of scans. (16 bit scans are also called 48 bit scans because 16 bits are used to describe each of the three colour channels). 8 bit versus 16 bit is a description of how much information the computer is using ...
- Negative Scanning
Very thin, very dense, and very contrasted negatives (i.e. over or under developed, or poorly exposed) can be particularly difficult to scan. We will try if requested but the risk of muddy/noisy scans in these cases is yours. Generally speaking, if you can print the neg reasonably, it can be sc ...
- File Naming
Your files will come back with default names like 'untitled12.tif' - these names are created automatically by the scanning software. We are often asked if we can name each scan individually - we're sorry but we can't. This might seem silly to you but the only way we can offer our extremely low p ...
- File Rotation
We don't rotate your images - they are scanned in the orientation that the holder fits into the scanner. The Flextight software can take several minutes to do a basic rotation, so this is about streamlining our processes and keeping costs down for everyone. It only takes a moment to rotate the i ...
- The difference between PPI and DPI
PPI - Pixels Per Inch DPI - Dots Per Inch Unfortunately, in the world of imaging, PPI and DPI are used almost interchangeably. They are two quite different things and the confusion of the two leads to more confusion than almost any other single thing in digital imaging. The first things to und ...
- About the Imacon Flextight 949 Film Scanner
The Imacon Flextight 949 is a superb scanner offering a dynamic range of 4.4 and excellent sharp results, for prints up to really large sizes. It really is optically sharp at each of its resolutions, has excellent shadow penetration, and in Fine Art print terms, scans made here on our Imacon ha ...
- Cleaning old and dirty film
PEC-12 is non damaging, archival, film cleaning product and the best option we've found. Used in conjunction with PEC pads (very soft lint free disposable wipes) we've found no better product for cleaning film. It's not cheap but a little goes a long way. If you're desperate for some, fast, Nu- ...
- About the Nikon 4000 ED Film Scanner
The Nikon 4000ED is a remarkably sharp, capable scanner with 35mm film. It's not quite as sharp (particularly around the edges), or quite as good at penetrating the shadows as the Imacon, but it offers far superior automatic dust and scratch removal, and is a very cost effective solution. We've ...
- Our Scanning Methodology
For Image Science, scanning is a core service, and we have invested considerable time developing processes to produce the best possible scans. On Colour and Detail (or the clipping of scans). We do not clip your scans in any way. We believe a truly fine print is always the ultimate goal of sc ...
- Colour Spaces For Scanned Images
We scan images by default into the Adobe 1998 RGB colour space as this is industry standard (as defined by the AIPP and ACMP digital guidelines). If you use another colour space, we're happy to directly scan into your preferred colour space. Just let us know when you make your order. We can also ...
- Print Sizes From Our Scans
300 PPI is the de facto industry standard for printing resolution. When we talk about how big you can print your scans, we simply divide the resolution by 300 to get the number of inches. Hence a 5400 by 3600 pixel scan can be printed to 5400/300 by 3600/300 or 18 by 12 inches. Easy. If your o ...
- Dust and Scratch Removal
On the Imacon Flextight 949 When we scan your negs or transparencies, they are first cleaned using compressed air. The compressed air removes major dust particles, but film often has a slight static charge and some times dust stubbornly sticks to the surface. We DO NOT wipe your photos as the r ...
- How to build your own lightbox!
Summary: Gives complete instructions on building your own light box, complete with a Bunnings shopping list! A bit Australia specific in terms of the names of all the bits and bobs, but it shouldn't be too hard to adapt it for other countries. Transparencies never look better than they do on a ...
- Cheap source of IT8 targets for scanner profiling
If you want to calibrate a film scanner, you need a reference transparency. The best are the Hutch colour targets, but they are VERY expensive: Hutch Colour Targets Otherwise, you will use the industry standard IT8 target. This will give you 98 percent of the results of using a Hutch colour tar ...
- Post Scan Workflow Tips
A basic workflow for your images after scanning would be: Check media to make sure there are no disc errors, and burn a second copy for your archives. (If there are any disc errors - let us know ASAP and we can reburn your scans - they are on our server for a month after your scanning job). Cr ...
