The reason for the change is that Adox purchased the name &#8220;HC-110&#8221; in 2022 after Sino Promise dropped making chemistry for Kodak, and rather than let the name go, they snapped it up and used it to release a modern version of the original thick syrup HC-110. Also, for transparency, this is the second generation of the new formulation, made by Photo Systems Inc., not Sino Promise. <\/p>\n<figure style=\"width: 1024px\" class=\"wp-caption aligncenter\"><a data-flickr-embed=\"true\" href=\"https:\/\/www.flickr.com\/photos\/axle81401\/54956090977\/in\/dateposted\/\" title=\"Developer Review Neo HC-110\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/live.staticflickr.com\/65535\/54956090977_5835e9d724_b.jpg\" width=\"1024\" height=\"684\" alt=\"Developer Review Neo HC-110\"\/><\/a><figcaption class=\"wp-caption-text\"><script async src=\"\/\/embedr.flickr.com\/assets\/client-code.js\" charset=\"utf-8\"><\/script>Yes, it&#8217;s already starting to go a bit yellow, but no sign of sediment or crystals.<br \/>\nNikon D750 &#8211; AF Micro-Nikkor 60mm 1:2.8<\/figcaption><\/figure>\n<p><strong>Technical Details<\/strong><br \/>\nManufacturer: Photo Systems Inc (for Kodak)<br \/>\nName: High Concentrate<br \/>\nPrimary Developer: Phenindione-Hydroquinone<br \/>\nType: One-Shot<br \/>\nMix From: Liquid<\/p>\n<p><figure style=\"width: 1024px\" class=\"wp-caption aligncenter\"><a data-flickr-embed=\"true\" href=\"https:\/\/www.flickr.com\/photos\/axle81401\/54824618076\/in\/album-72177720329401904\" title=\"Carnegie\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/live.staticflickr.com\/65535\/54824618076_7d99be8922_b.jpg\" width=\"1024\" height=\"678\" alt=\"Carnegie\"\/><\/a><figcaption class=\"wp-caption-text\"><script async src=\"\/\/embedr.flickr.com\/assets\/client-code.js\" charset=\"utf-8\"><\/script>Minolta Maxxum 9 &#8211; Minolta Zoom AF 24-105mm 1:3.5-4.5 D &#8211; Kentmere 400 @ ASA-200 &#8211; Kodak HC-110 Dil.

While not as thick as <a href=\"http:\/\/www.alexluyckx.com\/blog\/2022\/10\/24\/developer-review-blog-no-34-510-pyro\/\" rel=\"noopener\" target=\"_blank\">510-Pyro<\/a> or <a href=\"http:\/\/www.alexluyckx.com\/blog\/2022\/03\/28\/developer-review-blog-no-27-flic-film-black-white-green\/\" rel=\"noopener\" target=\"_blank\">Black\/White &#038; Green<\/a>, it was harder to pour than most other liquid concentrate developers. Only <a href=\"http:\/\/www.alexluyckx.com\/blog\/2021\/04\/26\/developer-review-blog-no-16-ilford-ilfotec-hc\/\" rel=\"noopener\" target=\"_blank\">Ilford Ilfotec HC<\/a> was slightly less viscous than the original HC-110. Even after Kodak abandoned the older pint bottle and went to the 1L bottle, the viscosity didn&#8217;t change. After 2019, a specific chemical became harder to obtain, and Kodak was forced to reformulate the classic developer into a thinner version, similar to LegacyPro L110. Now this allowed for the developer to be more easily poured and mixed with water. You don&#8217;t need a syringe to draw out the concentrate, and it mixes instantly with water. The one thing that Kodak did not change was the dilution scheme. You can use all your standard HC-110 dilutions without switching to the Euro HC dilutions. And yes, even the alphabetical dilution designations are still valid. You have your official dilutions A (1+15), B (1+31), C (1+19), D (1+39), E (1+47), and F (1+79). You&#8217;re two unofficial dilutions in H (1+63) and G (1+119): your stand development dilution J (1+150), and a universal mix dilution U (1+90). One thing you do need to watch out for is that HC-110 requires a minimum volume of 6mL of concentrate to work so for more dilute mixes you might have to increase the final volume of your working solution, but you don&#8217;t have to use the entire amount in your tank. The biggest concern people have about the new mix is its longevity. Now I&#8217;ve had my bottle open for a year and a half, and it&#8217;s turned slightly yellow, but it&#8217;s still going strong and showing no sign of failure. And I don&#8217;t go through this stuff quickly, mostly sticking to Dilutions H and F. If you are concerned about this, you can always decant the 1L volume down into smaller amber-coloured glass bottles (say 250mL each), and then top off with canned air to displace any oxygen. It was also noted that the earlier versions of the new developer did develop a crystal sediment after only a short time, but I don&#8217;t know if that affected the overall functionality of the developer. This has not been the case with the second-generation Photo System Inc produced version, both the HC-110 and High Concentrate branding. Being a Phenindione-Hydroquinone developer, there are some environmental hazards. In undiluted form, the concentrate can, in large enough quantities, pose dangers to water sources and animals, and should be disposed of through your local hazardous waste unit. Once diluted and used in the development process, because of the small volumes of concentrate used, it is safe to dispose of through a municipal water system. Of course, don&#8217;t dispose of any film development chemicals into a natural water source or a septic system. And as always, if you&#8217;re uncomfortable, you can always store the used developer and dispose of it through your hazardous waste unit.<\/p>\n<p><figure style=\"width: 1024px\" class=\"wp-caption aligncenter\"><a data-flickr-embed=\"true\" href=\"https:\/\/www.flickr.com\/photos\/axle81401\/54793260451\/\" title=\"Classic Film Review - Efke 50 - Roll No. 2 - Kodak HC-110\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/live.staticflickr.com\/65535\/54793260451_00c2f1cd15_b.jpg\" width=\"1024\" height=\"657\" alt=\"Classic Film Review - Efke 50 - Roll No. 2 - Kodak HC-110\"\/><\/a><figcaption class=\"wp-caption-text\"><script async src=\"\/\/embedr.flickr.com\/assets\/client-code.js\" charset=\"utf-8\"><\/script>Nikon F5 &#8211; AF Nikkor 24mm 1:2.8 (Yellow-12) &#8211; Efke KB50 @ ASA-50 &#8211; Kodak HC-110 Dil.

H 12:45 @ 20C (Constant Rotation)<\/figcaption><\/figure><\/p>\n<p><strong>Applications<\/strong><br \/>\nThe bigger question is what can&#8217;t HC-110 do? HC-110 is a developer that is a jack-of-all-trades and, in the right hands, can do almost anything you want with your black-and-white film. If you&#8217;re looking at film types, HC-110 works well on both traditional and modern-grain film, as well as on films of every speed from slow to fast. And that&#8217;s only the tip of the versatility iceberg. If all you need is general-purpose development, stick with dilution B (1+31); it will give you a similar look to what you get with stock D-76. If you need high-contrast images, similar to what you get from scientific applications, then dilution A (1+15) will give you those results. If you aren&#8217;t a fan of short development times, you can always go with dilution H (1+63) and double the dilution B times, or take it even further and use dilution F (1+79) and multiply by 2.5 from the dilution B times. For those who want to increase further the compensating nature of the developer, dilution G (1+119) is the best bet. The one thing is that there are only a few combinations that call for dilution G, so some experimentation is required. HC-110 also makes a great developer for push and pull processing and has some anti-fogging capacity for expired films. Dilutions C, D, and E all line up with development times for DK-50 (Stock, 1+1, and 1+2, respectively). I&#8217;ve only worked with dilutions D (add 25% to dilution B times) and E (add 50% to dilution B times), but rarely C. You can also do stand development with HC-110 using what I call dilution J (1+150) and a 45-minute semi-stand development. And finally, there&#8217;s what I call dilution U (1+90), which, like dilution G, comes from Ansel Adams, who stated that if you expose a film at an ideal speed, you can use a 1+90 dilution and 18 minutes in the tank, and it will develop any film. I have used dilution J once, and the results were okay. I have yet to try dilution U, but I have seen results, and they look excellent. I have also found that HC-110 does respond well to both manual and automatic processing methods.<\/p>\n<p><figure style=\"width: 1024px\" class=\"wp-caption aligncenter\"><a data-flickr-embed=\"true\" href=\"https:\/\/www.flickr.com\/photos\/axle81401\/55086327041\/in\/dateposted\/\" title=\"Kerr Village | January 2026\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/live.staticflickr.com\/65535\/55086327041_15822e2251_b.jpg\" width=\"1024\" height=\"643\" alt=\"Kerr Village | January 2026\"\/><\/a><figcaption class=\"wp-caption-text\"><script async src=\"\/\/embedr.flickr.com\/assets\/client-code.js\" charset=\"utf-8\"><\/script>Canon EOS 3000 &#8211; Canon Lens EF 40mm 1:2.8 STM (CPOL) &#8211; Ilford HP5+ @ ASA-1000 &#8211; Kodak HC-110 (Dil.

As I mentioned in the previous paragraph, running HC-110 at dilution B will yield similar results to D-76 at stock dilution. But there are some noted differences: you do lose a bit of acutance (edge sharpness), there&#8217;s a loss of shadow detail, and slightly finer grain. The note about the grain is debated, as some folks report a coarser grain, so your mileage may vary. All this indicated that HC-110 dilution B makes a decent general-purpose developer. The one thing I have noticed is that HC-110 does increase contrast at dilution B, with a significantly greater increase at dilution A. Once you get into the more dilute mixes (dilutions E, F, H, and G), you do get a slightly smoother contrast. On low-contrast films, add a yellow filter to bring it back up. I have also found that you get back that shadow detail and increase your edge sharpness at these dilute mixes. I have also observed only a slight loss of sharpness during rotary processing. My favourite dilutions are B, F, and H, with H coming out on top, but if I have enough time, I&#8217;ll go with F. I have yet to try dilution G, but I do plan to test it.<\/p>\n<p><figure style=\"width: 1024px\" class=\"wp-caption aligncenter\"><a data-flickr-embed=\"true\" href=\"https:\/\/www.flickr.com\/photos\/axle81401\/55024864041\/in\/dateposted\/\" title=\"Winter Days | December 2025\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/live.staticflickr.com\/65535\/55024864041_45c90b5875_b.jpg\" width=\"1024\" height=\"665\" alt=\"Winter Days | December 2025\"\/><\/a><figcaption class=\"wp-caption-text\"><script async src=\"\/\/embedr.flickr.com\/assets\/client-code.js\" charset=\"utf-8\"><\/script>Minolta Maxxum 7 &#8211; Minolta Maxxum AF 24mm 1:2.8 (Yellow-12) &#8211; Kentmere 200 @ ASA-200 &#8211; Kodak HC-110 Dil.

Having used three of them (Ilfotec HC, original HC-110, and LegacyPro L-110), Kodak High Concentrate (Neo HC-110) works the same as all of these. The one thing Neo HC-110 has is ease of pouring and mixing; you don&#8217;t need to worry about syringes or pouring out that thick syrup. The one note of caution is that you get this stuff in its second generation, the bottles manufactured by Photo Systems Inc., as it is newer and doesn&#8217;t have the same quality issues as the first versions made by Sino Promise. While I always suggest a developer like D-76 as your entry into home development, the second developer would be an HC-110 style developer. And if space is an issue, a bottle of HC-110 won&#8217;t take up too much extra space, and you can extend the developer&#8217;s life by decanting it into smaller bottles and displacing the air. HC-110 is available at most photography stores, and you will pay a bit more than D-76, but it&#8217;s worth the money because it lasts a long time.<\/p>\n<p><figure style=\"width: 1024px\" class=\"wp-caption aligncenter\"><a data-flickr-embed=\"true\" href=\"https:\/\/www.flickr.com\/photos\/axle81401\/55171101026\/in\/dateposted\/\" title=\"Ricoh XR10 | The First Roll\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/live.staticflickr.com\/65535\/55171101026_317404c8b0_b.jpg\" width=\"1024\" height=\"673\" alt=\"Ricoh XR10 | The First Roll\"\/><\/a><figcaption class=\"wp-caption-text\"><script async src=\"\/\/embedr.flickr.com\/assets\/client-code.js\" charset=\"utf-8\"><\/script>Ricoh XR10 &#8211; SMC Pentax-M 1:2.8 40mm &#8211; Fujifilm Neopan Acros 100 II @ ASA-100 &#8211; Kodak HC-110 (Dil.

The reason for the change is that Adox purchased the name &#8220;HC-110&#8221; in 2022 after Sino Promise dropped making chemistry for Kodak, and rather than let the name go, they snapped it up and used it to release a modern version of the original thick syrup HC-110.
